CLUSTERS IN A CHAIN OF COUPLED OSCILLATORS BEHAVE LIKE A SINGLE OSCILLATOR: RELEVANCE TO SPONTANEOUS OTOACOUSTIC EMISSIONS FROM HUMAN EARS
Journal Title: Journal of Hearing Science - Year 2017, Vol 7, Issue 1
Abstract
Spontaneous otoacoustic emissions (SOAEs) provide startling evidence that there is an active process at the core of the mammalian cochlea, but the mechanism involved is unclear. Models involving single, active Van der Pol oscillators have found favor, but here we extend the system to a chain of coupled, active nonlinear oscillators. It is found that the inherent clustering of oscillators in the chain produces an effect in which each cluster, or frequency plateau, behaves just like a single oscillator, most clearly in terms of phase lock to external tones and phase slip in the presence of noise.

CORRELATION OF ASSR HEARING THRESHOLDS WITH ABR HEARING THRESHOLDS IN CHILDREN
Background: Hearing assessment in neonates, or in older children/teenagers with special needs, is very challenging since a pure tone audiogram is not possible due to lack of co-operation and click-ABRs are not frequency...
