Acoustic foam is designed to absorb sound waves, thereby reducing reverberation and echo within a space. It is engineered to absorb sound waves across a broad range of frequencies, from low to high. This absorption helps minimise unwanted reflections and reverberations, resulting in clearer sound and improved acoustics.

Main properties of acoustic foam

Open cell structure

The structure of acoustic foam maximises its surface area, allowing for greater sound absorption. It promotes airflow, making acoustic foam lightweight and breathable.

Density Variations

There are various densities, with denser foams offering greater sound absorption capabilities. Different densities cater to different acoustic needs.

Fire Retardant Properties

High-quality acoustic foam is often treated with fire-retardant chemicals to enhance safety. This treatment reduces the risk of fire hazards and ensures compliance with safety regulations in commercial and public settings.

Ease of Installation

Acoustic foam is typically lightweight and easy to install, making it suitable for both temporary and permanent applications. It can be adhered to walls, ceilings, and other surfaces using adhesive or mounting hardware.

Advantages of acoustic foam

• Improved sound quality.

• Noise reduction.

• Enhanced privacy – reduced sound transition between rooms.

• Spaces can be optimised as recording environments.

Disadvantages of acoustic foam

• Limited frequency range – most effective at mid to high frequency sound absorption.

• Durability – fragile and prone to damage from handling, impacts, and environmental factors such as moisture and UV exposure. Over time, the foam may degrade, lose its effectiveness, or develop unsightly deformities.

• Limited aesthetic options – limited options when compared to other materials.

• Cost – high quality acoustic panels can be expensive, particularly if used in a large area.
