The commonly stated range of human hearing is 20 to 20,000 Hz.[9][10][note 1] Under ideal laboratory conditions, humans can hear sound as low as 12 Hz[11] and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.[12] The human auditory system is most sensitive to frequencies between 2,000 and 5,000 Hz.[13] Individual hearing range varies according to the general condition of a human's ears and nervous system. The range shrinks during life,[14] usually beginning at around age of eight with the upper frequency limit being reduced. Women typically experience a lesser degree of hearing loss than men, with a later onset. Men have approximately 5 to 10 dB greater loss in the upper frequencies by age 40.[15][16]
Fundamental mode of the Schumann resonance is at the same frequency as alpha waves in humans
Alpha waves are neural oscillations in the frequency range of 8–12 Hz[1] likely originating from the synchronous and coherent (in phase or constructive) electrical activity of thalamic pacemaker cells in humans. Historically, they are also called "Berger's waves" after Hans Berger, the inventor of EEG.[2]
i think i lost it at about 15 kHz but I don't want to play that game anymore because the last three months have been the worst tinnitus of my life and that's not going to help
i can't tell what i can hear from the beginning.. i could only hear the definite sound from 50 Hz
