Critical Bands in Human Hearing

Critical bands are a phenomena created by the cochlea, the hearing organ within the inner ear. The cochlea has a logarithmic spiral shape as shown in Figure 2. Figure 2: Cochlea human hearing organ location This shape governs the ability to distinguish frequencies in the ear.

The width of the critical band (auditory filter) changes with center frequency The shape of the critical band (auditory filter) changes with signal amplitude Hall & Garcia, in press 1. Human auditory perceptual analysis is quantized into < 30 “critical bands” 2. of perceptually near-identical frequency analysis classes

Critical band. In audiology and psychoacoustics the concept of critical bands, introduced by Harvey Fletcher in 1933 [1] and refined in 1940, [2] describes the frequency bandwidth of the "auditory filter" created by the cochlea, the sense organ of hearing within the inner ear. Roughly, the critical band is the band of audio frequencies within ...

Audiology Audiometers ... audiograms were determined when a movable, narrow, and approximately rectangular band of noise was used as signal in the presence of one or more masking tones. In both cases changes in the masked audiograms as a function of bandwidth made it possible to measure critical bandwidth. ... Findings associated with the ...

The “critical band” kHz Spectral level Adapted from Schooneveldt & Moore (1989) Signal detection threshold increases with increasing masking noise bandwidth up to a point after which signal threshold becomes independent of masker bandwidth. Stimulus spectrum 2 Critical bandwidth = 400 Hz Schooneveldt GP, Moore BCJ. (1989).

CRITICAL-BAND COMPRESSION METHOD FOR DIGITAL …
http://www.splab.net/papers/2002/2002_09.pdf
A new method of processing speech for digital hearing aids was proposed. In this method, each critical band was compressed along the frequency axis. To implement this, we tested two algorithms based on a filter bank (FB) approach and the fast Fourier transform (FFT). Five profoundly hearing-impaired subjects participated in a perceptual experiment.
