In a given context, the right sound barrier wall might not seem to make much difference. In some situations where noise is abundant, the sound barrier is simply “noise,” and changing it is no big deal. On the other hand, in more modestly-used rooms with some foreground noise, the sound barrier can be more of a simple force multiplier.
When noise is provided from both the side and from above, the sound is still received through the same filter, but some of the low-frequency noise (e.g., bass notes) is prevented from entering the room. This helps alleviate the frequency content of background noise and creates a better stereo image. In-room recording uses this concept as well, using sound barrier walls.
Sound barriers on studio walls will drastically reduce or eliminate acoustic perturbations when amplifiers, speakers, microphones, and headphones are used. If the sound barrier does not achieve this goal, the noise floor will be damaged.
Automotive sound reinforcement systems have long employed the same wall configuration for separating signals from non-signals.
You’ll see them built this way in the record stores and other equipment areas of automotive operations.
The divide is also important when you’re building a new machine room. Your system must pass through the sound barrier to get to the correct signal. And if your system is new, there will be noise in between your listening environment and the component cable before the barrier wall.
The barrier wall looks like a short wall or a small pillar.
Plywood Floor Tiles – While MDF is used for our floor tiles, Plywood in good condition will continue to last far longer. Concrete as it ages is prone to cracking. This damage is not visible on the back of the fixture.
Use the latest age ratings of the floor tiles to make sure your floor tiles are good for many years. SAND – Hot Porous Sand – Also known as Hydrostain. Vibrant and diffusive , it is used in home construction for anti-friction surfaces such as a stove, clothes dryer, or sinks. It will not crack or soften when exposed to water because of the porous nature.
There are two kinds of frequency damage. Both are very difficult to repair.
Each of these will also be addressed in the next chapter.
Partial destruction of the wall is very difficult to repair. So all that one can do is minimize the damage by such things as applying a hearing buffer.
Here are some special considerations for this kind of damage.
Each of the sound barriers installed is associated with a unique sound profile. For the de-emphasis experiment, the sound equipment is made up of sound sources mounted on rotating drums. That’s a very specialized sound source, and thus a very specific combination of characteristics.
If your room has any kind of walls, cabinets, a wood floor or other objects that don’t line up perfectly with each other, there is a very strong chance that your room is no longer able to absorb and reverberate audio from outside.
It’s very common for people to use a sound barrier to absorb sound from outside their house, but it can often be problematic for each room in your house to have the same barrier as your live room. This can result in echo problems, and even overloading sound from the living room to the bedrooms.
Our personal experiences have taught us that a sound barrier is often the best solution, at least for smaller to mid-sized homes and apartments.
Adding another wall at the music room’s entry would require leaving the kitchen for the cut-glass dining room. However, a sound barrier at the wall could cover almost the entire entry way. Plus, the sound barrier would prevent “all this noise” from entering the kitchen.
That’s one possible application, but other potential locations include the entry corridor, the kitchen vestibule and the multi-use living room, all of which have four or five bedroom suites.
