Evaluation of Loudness in a Room Acoustic Model
The equal loudness contours were measured using an analytical model, which was constructed for rectangular rooms based on the Kuttruff’s room acoustic model. A stimulus can be presented through the room acoustic model to the subjects, via headphones. The results are in very close agreement with measurements in a real room. Two additional experiments were conducted to study the loudness as a function of reverberation time for different types of stimuli. The results showed that the effect of reverberation on loudness is negligible for a stationary stimulus. On the other hand, for an impulse train, loudness depends on both the reverberation time of the test room and the repetition frequency of the stimulus.
