Acoustic conditioning with wood acoustic panels is not the same in an auditorium as in a bar. Every space has its own permissible noise level.

The acoustic conditioning of a room directly affects the level of noise experienced inside. When the level of noise produced by a source in an outer space is evaluated, only the direct sound produced by that source is taken into account. However, when you study this within an interior architectural space, in addition to direct sound, you have to take into account the sounds caused by the reverberation of the first direct sound. Therefore, the acoustic conditioning carried out in rooms and spaces by carefully studying where the acoustic panels made of sound-absorbing wood,  are to go in order to control the reverberation of a room, is key in maintaining a space within acceptable limits for noise levels.

But what are those permissible noise limits? Each type of space has different ranges of permissible noise and, although it is always recommended to be advised by acoustic consultants and experts in acoustic material, permissible noise levels for each type of room are approximately as follows:
