| Abstract: | Haircell, the sound signal sensor in the auditory system, works in an environment full of noise. This noise has been demonstrated before to be a factor beneficial to the transfer of subthreshold weak signal. We further theoretically demonstrate that in suprathreshold signal situation, noise can still be a beneficial factor and enhance the haircell nonlinear transfer of suprathreshold signal. This reveals an additional constructive function of noise in hearing and provides theoretic foundation for relevant applications. |
