the problem isn't sound pressure level, per se. i had the experience of being in a room with two violinists playing bach's d double violin concerto. it was not especially loud, but the sound of the violin was unpleasant. i could listen to a flute at 85 db , or a french horn at 90 db and i would not mind.
thus the issue is quality of sound and timbre not necessarily loudness.
