Sound absorbers, example, it is necessary to prevent noise emitted by machinery from travelling to areas further away via reflections; one is interested in obtaining a sufficiently high absorption at the walls. On the other hand, the sound for audiences in auditoria like studios or concert halls must be enhanced by

Fundamentals of room acoustics,epends on the room volume and the room’s interior design; the reverberation time is short in small rooms and in rooms which have large absorbing surfaces. Large volumes with less absorption have reverberation times which can easily extend to a couple of seconds. During a period of 2 s, for instance,
