The level of sound that is barely audible in the absence of significant ambient noise is the absolute hearing threshold. It is the lowest sound level that is detected during a specific percentage of experimental trials. A statistical definition is necessary because, even for a single animal, the minimum detectable sound level varies over time (Richardson et al., 1995).
