Abstract: It is common for musicians to use ear protection during solo- or group-rehearsals within the genres of amplified music (pop, rock etc.). This is of course due to the often loud nature of some of the instruments involved, for instance the drum-set. In fact, the “strength” parameter, and thus the loudness aspect of the Reverberation Time parameter, is of little interest when addressing acoustics for amplified music. The room is not as an outset supposed to help bringing out the amplified sound. However, the notion of the critical distance (Hallradius) parameter has incorrectly led some acousticians to believe that as short an RT as possible would be the answer. Further, especially in larger rooms RT at bass frequencies can become dominant thereby destroying the clarity of the music which is bass heavy. Also, especially in larger rooms, if RT at higher frequencies is too low, then the dynamics and vivacity of the music suffers. In fact, there is a narrow field of tolerances of RT at various frequencies that should be fulfilled to obtain optimal musical conditions for amplified music in rehearsal rooms and spaces. ISO:23591 is a non-mandatory recommendation and therefor constitutes best practice.
