A listening test was conducted to assess the localization of consecutive sound events in simulated reverberant conditions. The stimuli consisted of two sound events, which were reverberant wideband harmonic sounds reproduced in a multichannel anechoic chamber. Localization threshold for the latter sound event was measured as the direct-to-reverberant sound level ratio with an adaptive transformed up-down method. The studied factors affecting the localization threshold were the time interval and pitch difference between the two sound events and the time gap between the direct sound and reverberation. The results indicate that all factors have a significant effect on localization.
