| Speech intelligibility in classrooms and lecture halls was investigated. Acoustical measurements in the rooms have been performed, with special concern about 125 ms of early decay phenomenon. Weighting function of early reflections relative energy derived from modulation threshold and speech modulation spectrum of signal is proposed. |
