Binaural Speech Intelligibility and Interaural Cross-Correlation Under Disturbing Noise and Reverberation

Abstract

Subjective tests were carried out in order to investigate speech intelligibility, and the possible relative improvements

that can be obtained in practical applications to acoustic communication systems, for different forms of presentation

through headphones: monaural, monophonic, binaural at 0º (in front of the listener) and binaural at ±30º (right or left,

relative to the listener), played back undisturbed, and also with the addition of extreme levels of disturbing noise and

reverberation, with a signal to noise ratio of
