WebAug 19, 2015 · The Fletcher-Munson phenomenon. This non-linear hearing phenomenon was first written about in 1933 by researchers Harvey Fletcher and Wilden A. Munson. Although the data and graphs they produced have since been improved upon, they were close enough that “Fletcher-Munson” is still used as a shorthand phrase for everything …

Why is the human ear most sensitive to 4000 Hz tones?

A-weighting is valid to represent the sensitivity of the human ear as a function of the frequency of pure tones. The A-weighting was based on the 40-phon Fletcher–Munson curves, which represented an early determination of the equal-loudness contour for human hearing. However, because decades of field experience have shown a very good correlation between the A scale and occupational deafness in the frequency range of human speech, this scale is employed in … Web120 dB (from 0 dB SPL to 120 dB SPL); The threshold of hearing to the threshold of pain.
