Objective acoustical parameters were developed using the outputs of a binaural, nonlinear auditory model. Results from various listening tests show that these parameters can have a high correlation with the human perception of various aspects of room acoustics. Furthermore, using the proposed framework the acoustics of a room can be assessed by evaluating arbitrary binaural recordings instead of measured impulse responses. This way, the temporal and spectral properties of the signal as well as the absolute sound pressure level are automatically taken into account in the assessment.
