How a Soundproof Wall Can Benefit You

At those times you'd like nothing more than to turn down the volume on the horseplay and screaming from the younger kids, or the boom boxes or TVs blaring from the rooms of the teenagers. You'd love to be able to hold an adult conversation with your spouse or guests without having to raise your voices to uncomfortable levels, but the reality is that your home was not constructed with noise control as a priority. Keeping you interior doors closed doesn't help much when you are surrounded by paper-thin walls. What can you do?

Where To Use A Soundproof Wall

You can explore the possibilities of adding a soundproof wall to the rooms of your choice. Your bedroom, home office, or family room are all great candidates for a soundproof wall or walls, but every home has its hubs of activity, and you can choose the rooms which will benefit most from noise control. Having soundproof wall systems installed in those rooms can make the difference between having a family chronically short on sleep and one which is rested enough to arrive at the breakfast table in good spirits and ready to take on the day.

Why To Use A Soundproof Wall

You'll also feel much more secure when sharing close moments with your spouse if you are protected with a soundproof wall, and if you aren't constantly pleading with your kids to turn down the music or tone down their games, they'll be much more likely to stay home where they are safe.

If you do any kind of work from home, having a soundproof wall in your home office will make it much easier for you to stay focused in spite of the distractions of active kids, a barking dog, or a noisy vacuum cleaner. If your business is one which requires you to see clients in your office, a soundproof wall will keep your interactions with those clients private. It may also leave your clients thinking that your home life is much more organized that it really is.

A soundproof wall will let you work uninterrupted, and if you spend much time struggling with numbers or writing correspondence, it may be a necessity. But if having a soundproof wall makes you a more productive earner, the extra income you earn will eventually cover the cost of installing the wall!

Soundproof Wall Installation

The cost of installing a Soundproofing wall, by the way, need not be exorbitant if you have s some basic DIY skills. You can simply glue some cork cushioning to the back of a sheet 1/2" drywall, and then glue the drywall to your existing wall. The glue should be used instead of either nails or screws simply because nails or screws will transmit sound vibrations. You can learn more methods of installing a soundproof wall by talking to a building contractor or you local homebuilder's association.

How to Get the Most From Your Home Projector Without Spending a Fortune

There are many things to consider about the home projector in order to get the best possible experience. While some people believe that throwing more money at the problem will fix it, optimizing the home theater experience can be done without spending a fortune.

There has been extensive coverage about buying cheap projectors, DIY projectors, and many other means by which you can save money on a home theater system and still enjoy a quality experience. How to get the most out of your projector without spending a lot of money is an important thing to think about.

Mounting

Not enough can be said about mounting. Proper mounting is very important. But how can that save money? Mounting on a shelf unit often results in dust build up. Keeping the filters clean and making sure that there is plenty of airflow will help you to avoid over heating the projector causing damage which is costly to repair.

Screen Selection

Selecting the proper screen is very important. Not only do you want to get the right screen to fit your home projector needs the first time (Rather than having to purchase another one for more money) but you need to get a screen that is suitable for the location where it will be mounted. Is the screen easily cleaned? If it is soft fabric, will it rip or tear? If it is something that will be easily damaged, can it be stored while not in use?

Screens can be built with protection as well. Using an "artsy" type cabinet covering with pictures, or even a painting of some sort will prevent the dust buildup on the screen, lessening the need to clean it with the potential of damaging it. It will also prevent any ripping, tearing or other damage that may occur to the projection screen due to unforeseen circumstances.

Lamp Care

Make sure that the mounting is such that the projection unit does not get bumped or jarred a lot. Constantly bumping or moving the projector can cause many problems that are costly to repair. The filaments in the head lamps are very fragile, much the same as a mantle in a lantern is. Constantly jostling or bumping the projector will severely shorten the lifespan of the bulb. This will result in costly replacements that should not be needed so frequently. Frequent bumping also causes electronic and circuit boards to lose connection or come loose. This can create the need for costly repairs as well.

Lens Care

Are the optic lenses being adequately protected when they are not in use? The projector optics can be a very expensive replacement part. Lens covers are important. Even if they do not come with the projector when it is purchased, they are well worth the price. Quite frequently, spending a little money up-front can save a great deal of money in unnecessary expenses later on.

Projector Covering

Building a small container, especially for shelf mounted units can offer a unique custom-design and look for the user, and perform vital functions as well. Inclusion of computer fans and a power supply at a very nominal cost will insure sufficient airflow to prevent overheating and prevent much of the dust and dirt from getting into the projection unit where it could harm the optics as well.

An ounce of prevention really is worth a pound of cure if the desired effect is to get the most out of a home projector system without spending a fortune.

Living Room Surround Sound Sans Wires

In the age of Wi-Fi, it's surprising wires still have to be draped across living rooms, tucked under carpets or run along walls for a quality home surround-sound setup. While wireless speaker systems exist, they haven't spread as quickly or as widely as they should have by now - largely due to high costs. But a new technology is a taking an innovative approach to eliminating excess wires.

Two new Mitsubishi television sets - the 46-inch LT-46149 and the 52-inch LT-52149 - incorporate the company's new Integrated Sound Projector (iSP) technology. The new technology builds home theater surround sound into the actual television set. In theory, this seems nearly impossible. How could a TV set sitting in front of a person replicate the experience of speakers positioned all around (even behind) the individual? iSP accomplishes this through a sixteen-speaker array that recreates true 5.1 surround sound from a cabinet below the screen. When a person takes the TV out of the box, he or she enters specific room dimensions into the set. The iSP then determines how to provide the best sound for that particular room. Through the use of an advanced algorithm, the iSP delays the sound in varying intervals to each of the 16 speakers. As a result, the speakers generate distinct sound beams that are focused both directly and indirectly to the listener. Supposedly, this practice recreates the experience of an actual surround-sound system.

With iSP technology being so new (sets just hit retailers in mid-July), there's not much feedback yet on how well the sets reproduce the surround-sound experience. But the idea behind the technology certainly is a good one. Of course, the major benefit of iSP is the elimination of all those pesky wires associated with traditional surround-sound systems. Running wires either requires some diligent cover-up work or accepting a living-room eyesore in exchange for theater-quality audio. But, should it work effectively, iSP could eliminate the need to have a receiver and speakers altogether. That, in turn, also eliminates an extra remote - a great benefit at a time when TV-viewing rooms seem to be jam-packed with more remotes than most users can actually keep track of. The sets also could be ideal for use in smaller or oddly shaped rooms like bedrooms, basements or attics, where surround-sound setups aren't entirely practical.

Though the Mitsubishi sets come with a hefty price tag, the eradication of wires and other benefits should immediately put this set in consideration for any serious videophile purchasing a new TV. Additionally, the LCD flat-panel sets with iSP also are equipped with a number of advanced video features. Mitsubishi boasts that 120Hz film motion allows for smooth, crisp, fast and slow action content. And Mitsubishi's Tru1080p delivers over two million pixels to a screen for a full and true 1920 x 1080 resolution. Meanwhile, Mitsubishi Plush1080p technology reformats 720p and 1080i signals for a sharper, clearer picture. And, when not watching TV, consumers also can turn the Mitsubishi sets into a works of art with GalleryPlayer - software that enables display of stunning high-definition art and photography. But even a Picasso pales in comparison to the notion of wireless surround sound.

Mitsubishi LT-46149 and LT-52149 TVs are available at electronics retailers with suggested prices of $3,299 and $3,699.

Home Theater Televisions - Recycling Your CRT

If you watch television and have an older CRT (cathode ray tube) or analog TV set, you have undoubtedly heard that by February 2009, you will need to have purchased a converter box in order to view basic television programming. Most of us already enjoy digital television programming with satellite or cable and won't need to do much to prepare for the change. However, if you are one of the estimated 20 million households that do not take advantage of these services but rather watches TV using an antenna, you will not be able to receive any programming after midnight on the February 17, 2009.

CRT television owners can choose to purchase a converter box using a government subsidized coupon for the purchase or they can buy a newer model television that can accommodate the change to digital, like an LCD or plasma screen.

The change made by Congress to transition to all-digital television has been put in place for several reasons:
1. Better picture and sound quality is available with digital television
2. More free channel options are available with digital television
3. Transitioning frees up more frequencies that can then be used by emergency services.

What's The Big Deal?
Because many homes may in fact be getting rid of their older television, there is a growing concern as to what to do with those older TV models. An estimated 75 percent of unused and broken televisions get stored away rather than recycled or disposed of. Keeping an old set around is really not a good idea. Older CRT sets contain anywhere from four to eight pounds of toxic lead, a fairly unhealthy thing to keep lying around your garage. Additionally, throwing these TVs into a landfill is not too environmentally savvy either because the lead can leech into the soil and groundwater if broken. Recycling can help prevent the release of this hazardous lead.

Additionally, television sets are big, clumsy, non-biodegradable objects that take up large amounts of space in our nation's landfills. Many states have already started prohibiting or limiting the ability to dispose of electronic devices in landfills. California, for instance, was one of the first states to pass a law prohibiting the throwing away of old TV sets, followed by several other states. The Environmental Protection Agency website can give you more information on limitations in your area.

How Can You Recycle Your TV?
There are a number of different options available to CRT and analog TV owners wishing to dispose of their sets in the most socially and environmentally responsible way. Before handing over your TV to any of these organizations or companies, however, ask some simple questions to verify that they comply with state or local electronics disposal laws and that they send any hazardous waste to a facility that specializes in the safe and legal disposal of such things.

Donate It To Charity: Consider giving your TV to a local charity, church or hospital. They may be willing to take it off your hands as well as pick it up from your home. You can contact the Electronic Industries Alliance for a list of local and national organizations that accept used electronic items.

Local Goodwill, Thrift Stores: Thrift stores will generally take an older TV set as long as it is in working condition. If you don't know where to start, simply make a few calls and see who might be interested.

Electronics Retailers: Some retailers, such as Best Buy, Circuit City and Office Depot will work with television manufacturers to sponsor in-store collection of televisions, computers and other electronics devices. This service is usually free or there may be a small charge. This is an incredible convenient option for people that want to dispose of a TV and get a new one all in one shop. Some retailers may even pick up the old TV set when they deliver your new one.

How to Turn Your TV Room Into a Home Theater

If you bought a 50" plasma and receiver with surround sound a few years ago and you want to kick it up a notch for the upcoming football season here's an idea...

Thanks to the fact that HDTV projectors are far less expensive than they used to be, you can turn your TV room into a full blown Home Theater for as little as $3,000.00. Here's the concept....use your plasma for most TV shows and when it's time to watch the big game or movie, turn your room into a home theater by sending your HDTV signal to a projector that shoots an image 120" diagonal on to a screen mounted in front of your plasma.

How to Do It

Screen: You are going to mount a retractable HDTV screen above and just in front of your plasma and mount a HDTV projector in the back of the room. The most common size screen is 120" diagonal. Determine what screen size you should purchase, go to mountsandmore.com

Projector: Sony is the biggest player in the front projector market. Two favorites are:

Sony VPL-VW60: Home Theater magazine says the "SonyVPL-VW60 is a" great projector at a great price". It projects a beautiful1080P image and sells for about $5,000.00.

If you're tight on money, the Sony VPL- AW15 is an incredible deal at about $1,100. No kidding, no typo! Although this model is only capable of projecting an image in 720P format, (1080 is best) Home Theater Magazine says "No rear projector or flat panel at anywhere near the cost can offer a big screen experience like this!"

Projector Mount: Due to variables like ceiling height, you're going to need a little help here. I suggest contacting projectorpeople.com and have them help you determine the correct projector mount.

Connections: Your HDTV projector only needs two connections, power and HDMI (high definition multi media interface).

Power: If you can afford it, have an electrician install a power outlet near the location you will be installing your projector. If you don't have the budget, just buy an extension cord that closely matches the color of your wall and run the wires as cleanly as possible to the nearest outlet.

HDMI: You will need to run a HDMI cable from your receiver to your projector. It looks best if you run your wires in the wall or under the carpet. You may want to have a home theater installer handle this for you.

You will need to purchase a HDMI switch as most receivers have only 1 HDMI out connection.

Black Out Curtains: The black in a projected image comes from the black in the room so you need to keep your room as dark as possible when you are in Home Theater mode. I suggest logging on totarget.com/ where you can purchase black out curtains and rods for as little as $29.99 each and install yourself.

If you're a do-it-yourself person, you can save some money installing yourself. If not, I recommend contacting finding pre screened contractors through the use of an online service called servicemagic.com/ Service magic is an on line contractor referral service that will get you three bids on anything you need to get done.

How You Can Increase the Lifespan of Your Projector Bulb Or Lamp

The replacement of projector bulbs is an all-too-frequent occurrence for anybody that has owned a home theater projector for any length of time. While a two thousand hour lifespan may sound like a lifetime to some people, rest assured it is not long before the projector lamp will need replacing. There are however, some general tips that can help to expand the life of a headlamp for the projection unit.

Do not touch the lamp with bare hands

One of the most frequent problems encountered is people replacing the bulbs with their bare hands. While this is fine for an ordinary light bulb, it is not a good practice for a projector lamp. The lamp in a projection unit burns much hotter than any regular light bulbs. The effects of touching it with bare skin are equally magnified and problematic.

Touching a projector bulb with the bare skin leaves traces of oil on the lamp surface. While this may seem a very minor detail, it is detrimental both to the bulb and the quality of the resulting multimedia display. The oils will get burnt onto the lamp and drastically reduce the lifespan. As the oil is baked into the surface, it actually diffuses the light being projected, reducing the lumens actually being sent to the refractive surfaces. The light will not be enough to project the image that has come to be expected from the home theater projection system. While the problem may not be noticeable at first, over the course of a little time, the quality will degrade to the point of not being viewable.

Turn off the projector power after turning off the lamp

It is highly recommended to turn the power on the projector to the "off" position only after having turned off the lamp and allowing it to cool. This will allow the cooling fans to do the job they were designed to do. While rapid cooling and heating result in repeated contractions and expansions of the bulb filament, it is much better that it be done more quickly with the cooling fans. Likewise, turning the projector on and allowing the cooling fans to run for a moment before turning on the lamp will help as well. This will add hours to bulb life expectancy and allow for longer hours of viewing pleasure on the home theater projection system.

Constant Movements

Constantly bumping or moving the projector, especially while it is hot can be very detrimental to the projector lamp. The filament in the bulb loses almost all tensile strength when it is heated during normal usage. It is much the same as the filament in a camp lantern. The principle is the same; the filament effectively becomes almost the same consistency as ash, making it extremely vulnerable to damage when it is hot. Even after proper cooling, the lamp filament is very sensitive. Care should be taken when moving the projector for whatever reason. While it is always a good idea to be careful with electronic equipment, some aspects of the home projector are actually a bit more sensitive.

It will usually be necessary to move the projector when cleaning the filters. As always, it is a good idea to move it carefully without jerking it around or bumping it any more than needed. Taking an extra moment or two to check the projector mount and make sure it is still securely fastened can also be beneficial and prevent slips and movement which may otherwise be harmful.

With a little care and a little preventative maintenance, the projector lamps will still need to be changed, but not nearly as often.

Bose Brings the Future of Home Entertainment to the Present With the Bose Lifestyle System Series

Creating a complete centralize home entertainment systems has always been a challenge for most of us due to factors like the number of rooms in the house, the massive amounts of equipment and wiring required, and not to mentioned the cost involved. Being able to create a network of audio and video equipment where all the components interact well with each other has for the most part been within reach of only a very privileged few.

Bose, the audio and video company known for cutting edge innovations, has created a solution with their Bose Lifestyle DVD Series, so advanced that it seems like it was ripped right out of a movie.

To start with, the Lifestyle DVD System delivers excellent home theater sound using their arrays of patented Jewel Cube speakers, a nice looking horizontal center channel speaker and a set of high-performance acoustimass modules, all included in the package.

This system in a nutshell, allows you to create a complete home entertainment network with top of the line components and smart technologies built right in to it. To get a better view of this advanced entertainment system, let 's begin with the brain of the network which, is the audio processor and DVD player . This component on the surface has the usual capabilities like the ability to play DVDs, VCDs, CD, MP3's, AM/FM tuner. It also allows you to record MP3s and comes with a connection to a your TV set through an HDMI port.

Underneath, however this system comes equipped with a unique Bose patented technology called ADAPTiQ and what this does is, it monitors the dimensions of your room and the placement of your speakers, and automatically calibrates the sound quality based on the acoustics of the room to achieve the best possible sound. So no matter what the shape and dimensions of your room are and where you place the speakers, ADAPTiQ will automatically calibrate the sound for you to achieve the best possible sound quality.

The second feature in this system is something called Bose Link Technology, and this is what allows you to establish the audio and video network throughout the house. BoseLink allows you to wirelessly link the main system to as many as 14 different rooms , so you can play a CD in the living room and deliver the sound to any of the other rooms, with each area having the ability to independently control the volume. What's more you can have a second audio stream, let's say an IPOD, and deliver that stream to any of the desired locations, so you can watch your TV in one room, while someone else listens to an MP3 somewhere in another room, all coming from the main hub.

As you can see the Bose Lifestyle system comes as close to completing a home audio and video network as you can get. The basic system comes with the main components and enough equipment to set up the main room, and speakers for any additional room would need to be purchased separately. However with the main system set up, you can expand the entertainment network to accommodate up to 14 other rooms.

How to Get a Home Projection System For Under $1000

While looking for home theater projection systems, many people are astounded at the high price of most units. However, there are many avenues available for people to find projection units, often at well under one thousand dollars.

While some of the manufacturers offer brand new units for less than one thousand dollars, is this always the best way to look at projector units? It depends on what the individual users needs are. Some people feel more comfortable having a brand new projection unit with a warranty and service readily available for their purchase. While most of the projectors available for this price are smaller units, designed mostly for media displays such as presentations, some home theater projection units are actually for the same low prices. This is definitely an option to explore. What if that projector does not meet the requirements of the user though? What are some of the other options available?

One of the easiest and most popular ways to get an affordable, high quality home theater projection system for under $1000 is through the use of online auctions. While there are specific concerns directly related to online auctions, with some care and consideration by the buyer some very good deals are available here. If the prospective buyer is adequately armed with the proper information, this can be a very good route to explore in depth.

Another viable alternative to otherwise high priced projection units is the Do It Yourself or DIY projector. With a little bit of know how, and some time and effort to put forth towards a worthy goal, it is possible to build a home made projection unit for the home theater system. Parts are readily available from an ever widening pool of resources and the actual technical know-how is not as intensive as it may seem. For many self-proclaimed handy men, this can be an ideal option. It will give the builder a productive outlet for their skills and a unique and distinct sense of pride when their friends come over to view the large screen home theater system that has been custom built by the user.

A variation of the Do It Yourself projector is the pre-made projector. While the concept is relatively new, it has become increasingly popular and an affordable alternative to the high priced new systems. Most of the companies that sell projector parts, whether new or used, get discount prices by purchasing the products at a wholesale rate.

While it is not feasible for most people to even think about going out and purchasing parts by the truckload, they can still benefit from the pre-made projectors. These same companies also realized very quickly that not everybody is capable of putting together a home made theater projection system. They had the technology, the manpower and the parts to alleviate this problem. While the specifications may vary, pre-made projectors are put together in a factory setting by qualified technicians. More often than not these will even come with some form of limited warranty. This can be a very popular option for those individuals not as singularly qualified for the more technical aspects of projector construction.

Whatever path is chosen, there are many ways to get a good quality home theater projection system for less than one thousand dollars.

HDTV Formats and Your Home Theater Projector

Projector owners take note. Using your projector and screen as a primary source for watching sports on television, as well as movies for the HDTV experience is possible without breaking the bank on a new HDTV projector. Now it sounds complicated, but consider these facts and gain a clearer understanding of HDTV and projectors.

All projectors in use today have what is known as a native ratio. This means that it has a standard format in which it produces images. Standard HDTV broadcast formats are 1080i (1920 x 1080), or 720p (1280 x 720). If the projector has a native ratio less than either of these two formats, the projector must re-format or scale (compress) the signal before producing the image, which results in the loss of some of the intended picture clarity from HDTV.

The bottom line is that all projectors are built to scale a wide variety of incoming signal formats into their one native display. They will all do standard television, they will all do DVD, and almost all of them will do HDTV 1080i and 720p as well. In addition, most of them will display a variety of computer resolutions, including SVGA, XGA, and so forth. Really, when it comes to HDTV, there are only two circumstances where scaling is not required: 720p for a projector with 1280x720 native resolution, and 1080i for a projector with 1920x1080 resolution.

The diminished picture quality is marginal, as a scaled HDTV image is still better than the analog or digital signal that some broadcasts are shown in. If your home theater is relatively new, you just got your projector, or you are worried that your projector doesn't do HDTV, it does. You are just seeing a scaled version of the HDTV signal.

Home Theater Speakers - More About Subwoofers

We all know what bass can do to a movie soundtrack. It can create drama, danger, even a feeling of strength depending on the visuals that go along with it. Bass is one of the most important elements of any audio format because it provides balance and contrast to the overall score of a movie, television show, even commercial. Quality bass in a sound system is impressive while not being overpowering.

In a 5.1 surround sound system, one of the most common for home theater installations, the '.1' is the bass. The speaker for the bass sounds on a soundtrack is called a sub-woofer. Lower frequency sound waves use a larger diaphragm to move the amount of air it takes to make these sounds. While smaller speakers can produce these lower frequency waves, they typically cannot produce the kind of quality that one would expect from a quality theater. Smaller speakers can often sound tinny when trying to produce these lower sounds. Large home theater speaker towers are capable of handling this part of the soundtrack though it may require the reduction of sound quality from the mid and high range frequency speakers.

Choosing a good sound system with a quality bass speaker is not impossible, even for people who do not have a lot of experience. First, start with the sub-woofer. Homeowners will need to consider whether they require a passive sub or an active woofer. A passive sub-woofer does not need a separate power supply. Rather it uses power from the same amp that is driving the other home theater speakers. Volume from the amplifier can usually be controlled, there is less control overall with a passive sub. An active sub has a separate power supply. This means that the signal received from the amplifier/receiver is enhanced by the sub-woofer itself, without taking any of the power from the other speakers.

Once you have your home theater sub-woofer and other speakers picked out, lay them out to get the best sound from each. Bass sound is omni-directional, meaning that it goes out from the speaker in all direction. To decide where to place the sub-woofer, put it in the same position that you will be sitting in, whether it is on the couch facing the television screen or in a home theater chair. Turn on a favorite film then move around your room and listen. Find the spot that the bass sounds best and move your sub-woofer to that location. It can be set on the ground, on a shelf or off of a wall depending on where you feel the best low tone sound is heard. Since the sounds are going out and bouncing around the room in roughly the same direction, the sound should be great when you get it into place.

We've all heard the laments of mothers and fathers forced to deal with the incessant thumping and pounding of boom box bass lines from their adolescent's car or room. There is something to say for the potential for this phenomenon to occur in a home theater as well. While walls, ceiling and floor will generally block high sound frequencies from leaving the room, they can actually increase the volume of the lower range sounds. While laying out your speakers, try to also find the right volume balance for all frequencies that your family can enjoy the sound quality a bass can provide without driving your neighbors crazy.
