What is it about?
One of the most salient features of auditory brainstem responses to transient sounds is that latency decreases as stimulus level increases. One of the most salient features of cochlear mechanics is that sharpness of tuning decreases as stimulus level increases. This paper suggests a modeling framework that reconciles these two experimental observations.

Why is it important?
Having a single theoretical framework to explain multiple independent experimental observations contributes to our understanding of the function of the inner ear.
Perspectives
In 1988 I published an observation of auditory brainstem responses to tone bursts that revealed an extremely orderly pattern in their latency verses stimulus level and frequency. Since that time, I've been trying to understand the role of cochlear mechanics in producing this orderly pattern. This paper represents a breakthrough in my understanding of some signal-processing aspects of cochlear mechanics.
