Acoustic foam

Acoustic foam is an open celled foam used for acoustic treatment. Reducing reverberation, reflections and flutter echoes which cause sound interference and effectively absorbs energy contained within a variety of sound waves. This prevents them from bouncing around rooms and causing sound distortion.
With its high-performance soundproofing and noise reducing properties. It is an ideal solution for industrial, commercial, and residential projects, new builds and renovations to reduce Noise Pollution.
Acoustic Foam can be made in several different colours, sizes and thickness.

Acoustic enhancement

The objective is to enhance the properties of sound by improving speech clarity and sound quality.

For this reason, the foam is often used in recording studios. The purpose is to reduce, but not entirely eliminate resonance within the room. This is achieved by placing similar sized pieces of foam, often in the shape of cones or triangles, on opposite walls.

Note: Polyurethane foam can discolour when exposed to UV light. Discolouration can be prevented by coating the foam with an acrylic or water based paint.

How acoustic foam works

Acoustic foam is a lightweight material made from polyurethane foam either polyether or polyester, and also extruded melamine foam. It is usually cut into tiles – often with pyramid or wedge shapes – which are suited to placing on the walls of a recording studio or a similar type of environment to act as a sound absorber, thus enhancing the sound quality within a room.

It reduces or eliminates echoes and background noises by controlling the reverberation that sound can make by bouncing off walls. This type of sound absorption is different than soundproofing, which is typically used to keep sound from escaping a room.

This foam deals more with the mid and high frequencies. To deal with lower frequencies, much thicker pieces of acoustic foam are needed; large pieces of acoustic foam are often placed in the corners of a room and are called acoustic foam corner bass traps.

Applications

Acoustic foam is primarily used in recording studios to minimise sound echoes. However, it can perform the same function in home theatres, manufacturing facilities, equipment warehouses, home offices, gymnasiums and auditoriums. It can be placed in any room where an optimal sound mix is desired.

It is often used to reduce echo’s by attaching it to the walls of large rooms, like churches, synagogues and temples. Using jagged acoustic foam to baffle the sound can help, as does hanging sound baffles that break up the empty space in high ceilings and large rooms.

The effectiveness of acoustic foam panels can be increased by ensuring there is an air gap between the foam panels and the walls. Doing this exposes a great surface area of the foam panels to incident waves increasing the amount of absorption. Spacing the foam from the wall also has the advantage of reducing any damage spray adhesive would have on a wall or painted surface.
