The binaural sound pressure level (BSPL) is an acoustic
parameter that is the sum of two sound pressures applied to the listener's left and right ears. The binaural sound pressure level is calculated from the logarithm of the sum of the two sound
pressures.Like the normal sound pressure level, the binaural sound pressure level is expressed in decibels
(dB). The measuring device used is the artificial head known from artificial head stereophony, since it simulates the human head. The binaural sound pressure is used, for example, for sound reinforcement measurements in halls, opera houses and concert halls.
