Auditory thresholds for 10 subjects were obtained for speech stimuli reverberation. The reverberation was produced and manipulated by 3-D audio modeling based on an actual room. The independent variables were octave-band-filtering (bypassed, 0.25 - 2.0 kHz Fc) and reverberation time (0.2 -1.1 sec.). An ANOVA revealed significant effects (threshold range: -19 to -35 dB re 60 dB SPL).
