What Do You Need to Know About Your Home Theater’s Acoustics?

Home Theater Acoustics — Des Moines, IA — A Tech

Whether you’re building a home theater from scratch or renovating an existing room, few aspects will be as critical as the room’s acoustics. While you may have the freedom to design the perfect theater space in a custom home, most homeowners will need to work with the room they have. Luckily, you have plenty of ways to modify and improve the acoustics of an existing space.

Equipment can come and go as technology improves, but the acoustics of your room will continue to impact your enjoyment of your home theater for its entire lifetime. By understanding the essentials of enhancing your room’s acoustic qualities, you can turn a good home theater into a great one.

Understanding Echo and Chatter

Room echo is one of the most significant problems you will face as a home theater enthusiast.  Sound waves that bounce off of walls and other reflective surfaces can create excess noise that obscures the material that you want to enjoy. Too much echo creates a chattering effect, which can reduce the quality of all kinds of media, from movies to music.

On the other end of the spectrum, a room that absorbs too many soundwaves can feel sterile and lifeless. If you’ve ever been inside of a recording studio, then you know that such an extreme level of deadening can be off-putting. While rooms with this level of sound absorption have their uses, they do not make an ideal environment for enjoying movies, games, and music.

For most home theater owners, the goal is to achieve a balanced level of acoustics that allows for clean sound without dulling the impact of intense action scenes or soaring music. Installers usually deaden unwanted reverberations by using sound-absorbing panels, curtains, or floor mats. As with most aspects of home theater design, the best option for you can be subjective.

Taming Your Reflections

Building the acoustics for your perfect home theater is all about taming sound reflections. While it may be tempting to cover every surface in sound-absorbing material, this approach will typically fail for several reasons. Not only will an entirely deadened room feel dull and lifeless, but not all sound treatments provide equal levels of sound absorption for all frequencies.

Instead, controlling noisy rooms is about locating likely reflection points and treating them to reduce unwanted frequencies. Typical acoustic foam wall panels minimize high-frequency noise, for example, but tend to do a poor job with low-frequency sounds. For enhancing the response of your subwoofers, you’ll usually use bass traps constructed from various types of fiber.

Likewise, placement varies depending on the type of frequencies that you need to absorb. Foam sound panels designed to control high-frequency echoes work best when placed on reflection points along the walls. On the other hand, bass traps are more effective when placed in the corners of a room to target the areas of highest sound pressure.

Finding the Right Balance

How many acoustic panels and bass traps does your room need? The answer will depend on everything from personal preference to the size and shape of your room. In many cases, finding the perfect balance for your ears will require some trial and error. Once you’ve identified reflection points for your speakers, adding and removing acoustic panels can be a sound way to find a configuration that works for you.

Remember that more isn’t always better. Although some installers may recommend treating a certain percentage of your walls, the impact of each panel or bass trap will vary based on other characteristics of the room, such as the wall material or furniture placement. For this reason, approaching acoustic design for your home theater with an open mind is often better than a one-size-fits-all approach.

    Todd at A Tech did an awesome job setting up all the electronics in our basement. We have surround sound and all of the electronics are hidden in a closet with only 1 remote. My husband is techy so he worked with A Tech more than I did but my only request to Todd was that I needed to be able to watch tv and play a dvd without asking for help (I am not techy!) One fabulous remote runs everything and has pictures and an easy menu! They also fixed the internet issue in our house! Very Happy Customers!

    Todd designed a whole house audio system with separate controls for every room with one receiver. He was extremely knowledgeable about speaker placement, size and quality. The end product is amazing. He also recommended a remote that controls everything. This is one of my favorite features. I have also purchased several items for my garage organization that I love. They have everything from home audio, garage organization to kitchen items in the store. Will continue to do business with them as I still need closet organization.

    We have had our Beam Central Vac for over 15 years and absolutely love it! It is convenient, easy to use and best of all - keeps the 'dust' out of the home!. We have had very good service when we needed it, we replaced the motor in the unit once (very reasonable) and had replaced the power brush handle once. Pretty good for a unit that is over 15 years old! The folks at A Tech Easy Living Store are knowledgeable and very willing to assist in any way they can. Highly recommend visiting the store! They have LOTS of items that can make your life easier in your home!

    Great products! Exceptional Service! I was out of idea for what to buy my wife. I stopped at The Easy Living Store and they had all I needed to make her happy. I would have never thought of a self opening garbage can as a great gift idea, but they said she would love it and she did! I was amazed at everything the store had to offer and how helpful the staff was there. I will go back.

    Todd did an awesome job getting all the components into our basement home theater system that my techy husband wanted plus making it easy for me to run with only one remote. We are very happy!

    I have hard wood floors and Beam has a attachment I bought it at the store and it is a God send I simply love it, it is a dry mop on the vac! Amazing! I'm buying a spare mop when I go back! I bought my vac at Van Berkum's in Pella (Where I live) never will I go back there, they sent my head out for as a loaner and gave me some one elses. How is that for doing business! We argued for a long time about this and was getting no where she kept saying that it was my head, I will never go back there to buy anything! I'm 60 minutes from Des Moines and I will take my vac to be serviced at the Easy Living Store anytime!

    wish every home repair could be this easy!!! My central vacuum was having issues, burned out motor, poor connection and an outlet issue. The technician called me a bit early and said he was ahead of schedule, perfect! He was waiting when i got there, diagnosed it in about 10 minutes, I asked how long it would take to get the parts, he said he had them on the truck! I thought maybe they were generic, but when they made the appt they asked what model. He made the right diagnosis and fixed in about 20 minutes! Couldn't really ask for much more!!! The only remote downside was when I called on saturday the lady asked me to call back on monday. Great service and a great experience!

    I live in a 50's home. I had A Tech come and redo my closets for me. They had great ideas, listened to my input and now I have great closets, even though I live in an older home!
