Auditory Sensing Systems: Overview

Detailed Description

Auditory sensing, or the sense of hearing, is concerned with detecting and extracting information from pressure waves in the surrounding medium, typically air or water. Since waves are generated by movements or collisions, this primarily tells the perceiver about things happening in the environment. In addition, since pressure waves can be reflected, absorbed, and refracted by other objects, these pressure waves also contain a great deal of contextual information about the environment and the objects in it. A fundamental challenge for the auditory system is to segregate the contributions of individual sound sources to the sound pressure waves received by the sensors as these are made up of a combination of all concurrent sources and their various reflections. Sounds unfold in time, so modellers of auditory processing cannot ignore time and the need to process signals within time; this becomes especially challenging when considering the multiscale nature of the...
