How Sound Absorbent Products Work

Cutting out noise can help to increase productivity and enhance the quality of work in offices and other spaces that are filled with noisy equipment. It can also improve workplace safety by eliminating distractions and reducing the risk of accidents. The good news is that there are a wide range of options available for those looking to reduce the amount of unwanted sound in their premises, from absorbing foam to acoustic panels.

While sound absorbent prevents sound from entering or leaving a space by blocking transmission with dense, heavy materials, sound absorption products are designed to improve the internal acoustic quality of a space by reducing echo and reverberation, using light and porous materials that trap and convert sound waves.

Understanding Sound Absorbent Materials and Their Benefits

Absorbent products are made from soft, porous material such as fabric or foam. As sound passes through these materials, the vibrations are absorbed and converted into heat energy, which in turn causes the sound waves to lose intensity as they continue on their path. This reduces the amount of reflected and transmitted noise that can cause echo and reverberation within a space, making it quieter and more pleasant to be in.

The performance of porous absorbent material is often measured by its Noise Reduction Coefficient (NRC) – a descriptor that gives an indication of the effectiveness of the product at specific frequencies. The higher the NRC, the better the sound absorbing material is. The thickness of the sound absorbing material will have an impact on its performance, with thinner materials proving more effective at lower frequency ranges.
