Acoustics – Absorbers
The purpose of absorbers is to reduce the total energy of a sound source. This is achieved by creating an amount of open area on a panel surface. The absorbing surface takes away unwanted sound and consequently contributes to a lesser intensity of sound. The challenge is to find a balance between the absorbing area and the reflective areas of a room to achieve a comfortable and purposeful acoustic depending on its use.
Bass absorbers can be useful in small meeting rooms or similar localities to control the distribution of low frequencies. Concentrations of sound waves occur often in the corners of rooms causing disturbing echo and sound reverberation. This can be relieved effectively by the installation of bass sound absorbers in the corner areas.
Bass absorbers can be utilized in locations such as ¬conference rooms or studios where there is a need to control low-frequency sounds either from voices or music.
The size of the panels and the distance of the panel vary depending on which frequency to be regulated. They should therefore be chosen in consultation with an acoustician.
