Sound Barrier
Technology

Have you ever been in a room where you could hear too much bass? That happens when the low frequency energy created by a bass or drum note, completely overwhelms the room and all you hear is bass. At that particular moment in time you wonder where the mids and highs went. They were in the room but they could not be heard. Why is that? Where did they go? Well you know full well that your speakers and amplifiers produced them. So why couldn’t you hear them?

How about being in the room next to the music. Every time a drum or bass note is struck you wonder why you are hearing more of that note than they are actually hearing in the music room itself. Why isn’t the sound absorbing material inside the music room absorbing that excess bass? Why does the bass sound better in your room than the room in which the music was played?

Sound Barrier Technology – Listen to your music, not your neighbors.

It’s the same issue that occurs when you are listening to music in your room and a garbage truck goes down your street. All you hear can in your room is the garbage truck and not your music. This happens because the low frequency energy from outside your room has entered your room through your room walls. A series of 30′, 40′, and 50′ long low frequency waves are traveling from the source and crashing right through your room walls.

Maybe a motorcycle goes by and all you hear is the high pitched noise from the engine and its exhaust system. Maybe its individuals in the other parts of your building who can be heard flushing toilets and running tap water.

Why is all of this noise leaving your room and also entering it from outside sources? As Pink Floyd said, its time to build the wall!

The easiest way to keep the sound that is generated within your room where it belongs, and to keep outside noise from entering your room, is to construct a barrier between the outside world and your room. You need this barrier between the source of the noise and yourself and your room.

What type of barrier do you build? You build a barrier that shields you from the frequencies of noise that are giving you grief. What are those frequencies? The only way to find out is to measure both the frequency and amplitude or strength of those frequencies during the time of day or night that you are experiencing the noise issues.

If your neighbors are complaining your stereo is too loud, you can simply turn it down. If the garbage truck is the source, then you must construct a barrier between you and the truck.

Lower Pressure Levels

Lowering the energy and pressure levels generated inside a room is what low frequency absorption in small room acoustics is all about. Keeping low frequency energy from a motorcycle and train from getting into the room is the task for barrier technology. We build a barrier between the outside noise levels and ourselves. We do this through various construction and material techniques arranged into a certain order to achieve the correct amount of sound transmission loss.

Sound Loss Costs Money Per Db.

We have experience in barrier technologies and their application. Consult us before you build your room. We can assist you with starting points and which of your sonic expectations can be realized and which ones can not based on the level of work involved and the associated costs. Reducing sound energy levels has an incremental cost structure to it and most of the time, individuals spend to much to obtain too little. knowing what your goals are and then refining them to match the costs involved is best done with a pen and paper, rather than a hammer and saw.

Living Roof Home Theater

In the photos you can see a sound room of our design currently under construction in Arizona. The room is 25′ x 16′ x 50′ with a living roof which is composed of 18″ of earth. The walls are all 8″ poured concrete. All doorways are steel framed and supported.

Our staff can assist you with finding the right sound barrier technology for the noise issues you are facing. First, you will need to quantify the actual noise issues and put a number to them. It is this number that determines what type of sound barrier technology we should use, what materials it should be made from, and how thick it needs to be along with the cost.

If the noise from outside is your garbage truck, then that is low frequency noise and will require a different type of sound barrier technology than the high pitched whine of a motorcycle. As a general rule, lower frequency noise issues require thicker barriers with much more mass than higher frequency noise issues. Selecting the correct sound barrier technology for your particular noise issue is critical and must be left to professionals skilled in measurement and construction to correctly manage these barrier noise issues.

What Will You Experience?

  • We can measure your noise issues and identify numerically how large and at what frequencies you have problems at. This will put a number to your issues and with every number comes an associated cost. You do not want to spend more than the noise management issue requires.
  • We can analyze your current construction methods in your walls and possible modify the existing structure to produce the isolation required. This will save you time and money.
  • We can show you what materials and methods of construction will work best for your noise issues. Every noise frequency has materials and methods of assembling those materials that will work best and at cost savings.

Sound isolation technology requires construction methodologies that center around vibration reducing techniques. Different materials must be married together in the proper manner to ensure that vibrations are minimized as they pass through the materials. Special care and attention must be used to make sure all surfaces are mechanically decoupled from each other,room size calculations are completed to ensure proper room resonance control on the inside, and barrier technology must be employed to yield the highest sound transmission loss at the lowest price point.
