    To see what frequency range you can hear


    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]

      i could it right from the start...but it goes dead at 12000

      and not sure if i have dead spots in one ear or the tracks are adjusted but around the middle it shifted and drifted sides using earphones

    The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth's electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth's surface and the ionosphere.[1]

    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

          Is it a test ? I started to hear it at 32 HZ and lost it at 8000
