Implementation of intelligibility algorithms into EASE 4.0

摘要

in acoustic simulation programs very different algorithms are used to calculate the intelligibility of speech and music. The desired results are obtained by postprocessing fixed energy ratios as well as time-depending impulse responses. In EASE 4.0 there are have been implemented now all usual intelligibility measures, derived by means of simulated high resolution data or by applying statistical estimations. This paper compares all these measures and methods like STI, AlCons, definition etc. by means of the results obtained within a common computer model. Recommendations for applications will be given finally.
