Hearing’s frequency-dependent sensitivity makes noise-position control possible

Evidence

For pure sine waves, however, the sensitivity to change is markedly different and is a strong function of both amplitude and frequency. For example, at 1 kHz, the just-noticeable amplitude change varies from 3 dB at 10 dB(SPL) to 0.3 dB at 80 dB(SPL). — David M.
