Acoustic sound foam is a special kind of foam commonly used for acoustic treatment and insulation. It works by increasing the air resistance of airborne sound waves, thus reducing their amplitude and giving the sounds a calmer and more soothing vibe. The energy involved in this process is then dissipated as heat. Many people who plan to set up a home theatre take advantage of the benefits acoustic sound foam has to offer. This material is very easy to use, since it comes in several different sizes, thickness, and colours. Its versatility also extends to the fact that it can be attached not only to walls, but also ceilings and doors.

Uses of Acoustic Sound Foam

There are generally two uses for acoustic sound foam: acoustic enhancement and sound blocking. The main objective when using foam for acoustic enhancement is to enhance sound properties by improving the quality of sound and the clarity of speech. This is why the material is often used in recording studios and home theatres. It’s meant to reduce resonance without actually eliminating it and this purpose is achieved by placing similarly-sized foam pieces on opposite walls, usually shaped in cones or triangles. It’s also meant to reduce echoes in a room, particularly when it’s attached to the walls of temples and churches.

When using acoustic sound foam for sound blocking, the main objective is usually to prevent sound from entering or leaving a particular room. For this purpose, the material has to be placed in all the walls of the room as well as on the floor and ceiling, thus eliminating all resonance within the enclosure. Jagged acoustic foam can also help baffle sound in the same way sound baffles work to break up empty space in large rooms with high ceilings. The best acoustic foams are generally those with protruding spikes or pyramids, which are known to increase sound absorption.

Benefits of Acoustic Sound Foam

Aside from the uses mentioned above, there are several benefits that can be gained from using acoustic sound foam in your home theatre. For one thing, many such products are treated with fire retardants, so you can be assured of its safety. It’s also very easy to shape and use, and is made of just the right materials and bubble size to attain maximum absorption of a wide range of frequencies, from the highest pitch to the lowest bass. Of course, you’ll have to install the foam properly and in the right proportion to be able to take full advantage of these benefits.

Among other things, you’ll have to make sure the width of your foam is in the right proportion to its length and height in order for you to enjoy all of its benefits. Remember that it’s not advisable for you to cover your home theatre entirely with the foam because doing so will make the room seem extremely tightly-packed and give the sound an unnatural quality. And if you feel that using acoustic foam is overkill for a home theatre, then you may substitute it with acoustic curtains. But if you do, then you should be prepared for a less-than-ideal effect compared to what you’d get with acoustic sound foam.
