Abstract
A method and system of estimating human perception of audibility of audio alerts in the presence of background noise. In the audibility estimation system, a microphone generates an input signal corresponding to an audio alert. A processor receives the input signal and generates an audibility metric representing human perception of audibility of the audio alert based on a comparison between a background noise estimate and an audio alert estimate, and causes an action to be taken based on the audibility metric.
