Critical Bands in Human Hearing

https://community.sw.siemens.com/s/article/critical-bands-in-human-hearing

Critical bands are used in the calculation of several different psycho-acoustic sound metrics, including loudness, fluctuation strength, roughness, prominence ratio, and tone-to-noise-ratio. Critical bands are similiar in nature to octave bands. Why do critical bands exist?

EQuivocate (along with Elevate, Punctuate, and Saturate) is designed to boost and cut along between the critical bands. By default, the frequencies for crossover are based on the Mel Scale (short for Melody Scale). Rather than being spaced based on the slopes given by electrical components (like vintage shelving and parametric EQs), or based on octaves (like …

Concept of Critical Band •Think of the basilar membrane as divided into 24 sections, the so-called critical bands •As long as the frequencies of the complex tone are within one critical band, the same group of hair cells is involved in “tickling” the nerve ends.

The bandwidths of the critical frequencies range from 100 Hz at low frequencies to 3500 Hz at high frequencies. The bandwidths of the 25 1/3-octave bands range from 11.5 Hz for the 50- Hz band to 2900 Hz for the 12.5-kHz band. Figure 2 shows the relationship of critical bandwidth to 1-3-octave bandwidth.
