AbstractWorkers often have to be vigilant for critical auditory signals in the presence of loud noise. However this phenomenon appears to have received relatively less attention especially when the signal-to-noise ratios (SNRs) are less than unity (or - ve dB). In this study we focus on alarm vigilance in the presence of loud pink noise (80 dBA) and with SNR of -18, -21, -24 and -∞dB. The results show that people with no known hearing impairments, were able to detect a 56 dBA alarm in the presence of a noise level of 80 dBA (i.e., a SNR of -24 dB). The findings can help to establish threshold boundaries for audible alarm signal in the presence of loud noise.
