Acoustic Foams for Sound Proofing

The sound of music reverberated beautifully throughout the room providing the effect that the users had desired for a long time now. Peter was happy that he had taken his friend’s advice and made his recording room sound proof using acoustic foam.

Acoustic Foam – What is it?

Acoustic foam is an open-celled foam that attenuates airborne sound waves and thus offers sound proofing. It does this by increasing air resistance, which reduces the amplitude of the waves. When this happens the energy is dissipated as heat.

Acoustic Foam

Acoustic foam is surely an answer to prayer because it helps in noise reduction. A studio or home theater that is treated with acoustic foam offers better sound quality because once acoustic foam is installed there the liveliness of the room can be controlled and the response of the room improved. Acoustic treatment ensures that the recording, mixing, editing and monitoring is accurate. Apart from this, acoustic treatment also gives the user added ability to record and monitor accurately.

The presence of acoustic foam in the room results in more accurate recordings and also allows you to hear exactly what is supposed to be recorded. The unfavorable effect of the end result is reduced considerably reduced because of this sound proofing material. The environment you are working in is also considerably improved with this sound proofing material. You will feel much more comfortable in the room once you have installed acoustic foam, this feeling is sure to filter into your creativity, which will enable you to enjoy your work even more.

Apart from being useful, this material is easy to work with too as it can be cut and trimmed easily. It is also a cost effective way of treating your room.

How much of acoustic foam should I install in a room?

When installing acoustic foam in a room it should be used in percentages, this is because too much of acoustic treatment might result in recordings that are unnatural. Each room is different and takes a lot of planning, it is because of this that the installation of acoustic foam is done keeping in mind the width in proportion to its length and height.

Some of the percentages used in different rooms are:

• Rooms that are used for jazz, art, choral, classical and other foams of ensemble could use about 35% to 50 % coverage.
• For other rooms like the pop, rap, country, techno and others, 50% to 75% is usually enough.
• The mixing desk could do with about 50% to 85% coverage. For the rest of the mixing room around 20% to 40% should be enough.
• 75% or more of absorption is usually used for the isolation booth. 100% absorption might be required for a tight vocal booth.
• Well-designed live rooms vary in the levels of acoustic foam installation.
• For your home theatre use a lot of absorbing foam with some diffusion on the ceilings too.

It is important to note that each room is different and thus the percentages used vary. 100% of absorption is rarely required in a room and is advised against because the room will feel very closed, tight and unnatural. Leaving a part of the walls bare helps ensure that the room does not get overbearing.

I hope that this information will help you get the desired sound effect in your room!
