Human hearing resists linear time-invariant modeling except at the periphery

Evidence

A good example of a highly non-linear and time-variant system is human hearing. As a result, modelling of the auditory system is a complex task, and only some of its peripheral parts may be modelled in the LTI sense. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 359

Categorization

• QUESTION: Which peripheral parts of the auditory system are LTI-modelable, and where does the non-linearity begin critically?
• XREF: Ties directly to the reader’s stated goal of communication acoustics applications in hearing and biology.
