| Abstract: | It is important for alarm signals to be accurately perceived in any environments to avoid many dangerous situations. However, often cases of inaudible alarm signals arise because some interferences such as the masking effects of noise occur in noisy environments. In this study, to investigate the perception of the alarm signals, the masked threshold of binaural alarm signals in noise was measured as a function of interaural time difference (ITD) in which the frequency of the alarm signals is varied from 1.5 to 2.5 kHz. The results showed that the perception of the alarm signal is influenced not only by the ITD but also by the interaural phase difference (IPD) of the signal. This influence depends on signal frequency. This suggests that ITD and IPD at the alarm signal frequency have to be considered to convey warnings accurately and efficiently without loss of information. |
