Abstract
The article considers the question of auditory perception of speech and piano sounds, which have a relatively weak fundamental tone level against the background of high harmonics (formants of the vocal cords and string overtones, respectively). It is shown that the audible spectrum of these sounds is the spectrum of the interference envelope of the corresponding harmonics. This spectrum contains the fundamental tone as the dominant sound, which is clearly heard in speech and music, while the formants and overtones, initially dominant in the sound spectrum of speech and music, primarily influence the timbre of the fundamental tone. At the level of hypothesis, it is suggested that the interference envelope is detected as a result of the sound propagation in the nonlinear fluid medium of the cochlea of the inner ear.

Acoustical Physics is an international peer reviewed journal published with the participation of the Russian Academy of Sciences. It covers theoretical and experimental aspects of basic and applied acoustics: classical problems of linear acoustics and wave theory; nonlinear acoustics; physical acoustics; ocean acoustics and hydroacoustics; atmospheric and aeroacoustics; acoustics of structurally inhomogeneous solids; geological acoustics; acoustical ecology, noise and vibration; chamber acoustics, musical acoustics; acoustic signals processing, computer simulations; acoustics of living systems, biomedical acoustics; physical principles of engineering acoustics. The journal publishes critical reviews, original articles, short communications, and letters to the editor. It covers theoretical and experimental aspects of basic and applied acoustics. The journal welcomes manuscripts from all countries in the English or Russian language.
