| Abstract: | It is crucial to correctly detect alarm signals in noise conditions, for instance, especially in car environments. However, alarm signals are possibly masked by noises from engine, friction between tires and road, etc., in car environments. To design the alarm signals that can be easily detected,it is necessary to first understand the perceptual characteristics of alarm signals in noisy environments. In this paper, the masked thresholds of alarm signals in the presence of car noise were measured in the virtual acoustic environmentsgenerated by using head-related transfer functions (HRTFs). The main conclusions are: a) when the frequency component of alarm signals is 1.0 kHz, interaural time difference (ITD) and interaural phase difference (IPD) have great effect on the detectability of alarm signals in car noise; b) when the frequency component of alarm signals is 2:5 kHz, interaural level difference (ILD) except ITD and IPD also plays an important role in alarm signal detection when the signal is fixed in the front of listener. |
