binaural room impulse response, speech intelligibility, early reflections of sound

Early Decay Time exceeded the score of the T30 reverberation time but was ineffective in a small lecture room. The C50 clarity index for all the considered lecture rooms was the most informative.

Architecture and construction, room acoustics, renovating university lecture rooms, indoor ecology, administration in education

The results obtained are preliminary, since an analysis of the acoustic properties of a small number of rooms was carried out
