Acoustic Foam – The definition of Sound quality

Acoustic foam

Sound is part of our lives and all around us whether it is the sound of the alarm in the morning or the crash of a drum. Sound is a mechanical wave that is an oscillation of pressure transmitted through a medium such as water or air, composed of frequencies which are within the range of hearing.

Acoustics is the study of sound and acoustic foam has been engineered to provide excellent noise and sounds absorption properties. The objective of the foam is to enhance the properties of sound by improving speech clarity and sound quality. The best places to have the foam are on walls, ceiling and floors to eliminate any resonance as these surfaces tend to bounce all the sound which distorts it.

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.

Acoustic foam 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.

Acoustic 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.

Acoustic foam is primarily used in recording studios to minimize 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.

Acoustic foam is often used to reduce echos 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.

Acoustafoam offer a wide range of acoustic foam products with excellent noise and sound absorption properties. Our foams meet flame retardant standards, FMVSS 302, UL94 HF1 and CLASS ‘O’ (fire rated and will not burn).

We have a wealth of knowledge in many industrial applications using our range of foams. Automotive, rail, generators, construction, air conditioning and defence to name but a few.

Acoustic foam is supplied in block, sheet and CNC profiled to complex shapes. Foam sheets are available either with or without self-adhesive backings and as laminates.

Our self-adhesive acoustic foam sheets are easy to cut and fit to a clean surface. Simply peel off the backing paper, locate in the correct area and apply pressure.

For solving noise problems outside the area use one of our self-adhesive laminates with an added protective barrier.
Sheets come in a range of sizes or can be customised to suit your requirements.

Profiled acoustic foam sheets provide a greater surface area for increased sound absorption.

Foil faced and polyurethane faced acoustic foam sheets have a protective surface to stop contamination of the foam and are easy to wipe clean.
