Abstract
The reverberation perception in a concert hall is affected by many attributes although the reverberation time may be the most important. To study the contribution to the perceived reverberation from different attributes, a series of listening tests are carried out. The semantic meaning of the reverberation is studied with the questionary to audio engineers and architectural acoustician. The factors to be analyzed are selected based on this semantic study. The subjects are asked to judge the running reverberation impression caused by acoustic scenes simulated by measured or virtual room impulse responses. The reverberation time of the room impulses used in the tests to stimulate the sound field are from 0.5 to 6.0 seconds. Besides the reverberation time, the attributes taken into the consideration in the factor analysis include the clarity, the sound level, the energy ration of early to late reflection, the distance between the source and listener, the volume and shape of the room and also the content of the sound. Based on the result of the factor analysis, a functional expression is proposed to describe the relationship between the perceived reverberation and a group of attributes.
