  2. Hearing range - Wikipedia

    en.wikipedia.org/wiki/Hearing_range

    The commonly stated range of human hearing is 20 to 20,000 Hz. [6][7][note 1] Under ideal laboratory conditions, humans can hear sound as low as 12 Hz [8] 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. [9] The human auditory system is most sensitive ...

  3. Absolute threshold of hearing - Wikipedia

    en.wikipedia.org/wiki/Absolute_threshold_of_hearing

    It is approximately the quietest sound a young human with undamaged hearing can detect at 1 kHz. [4] The threshold of hearing is frequency-dependent and it has been shown that the ear's sensitivity is best at frequencies between 2 kHz and 5 kHz, [5] where the threshold reaches as low as −9 dB SPL. [6] [7] [8]

  4. Audio frequency - Wikipedia

    en.wikipedia.org/wiki/Audio_frequency

    t. e. An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz. [2][3][4] In air at atmospheric pressure ...

  5. Hearing - Wikipedia

    en.wikipedia.org/wiki/Hearing

    Human perception of audio signal time separation has been measured to less than 10 microseconds (10μs). This does not mean that frequencies above 100 kHz are audible, but that time discrimination is not directly coupled with frequency range. Georg Von Békésy in 1929 identifying sound source directions suggested humans can resolve timing ...

  6. Auditory system - Wikipedia

    en.wikipedia.org/wiki/Auditory_system

    Auditory system. Auditory system. Anatomical terminology. [edit on Wikidata] How sounds make their way from the source to the brain. The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system. [1]

  7. Neural encoding of sound - Wikipedia

    en.wikipedia.org/wiki/Neural_encoding_of_sound

    The wavelength of a sound is the distance between any two consecutive matching points on the waveform. The audible frequency range for young humans is about 20 Hz to 20 kHz. Hearing of higher frequencies decreases with age, limiting to about 16 kHz for adults, and even down to 3 kHz for elders. [citation needed]

  8. Infrasound - Wikipedia

    en.wikipedia.org/wiki/Infrasound

    Infrasound, sometimes referred to as low frequency sound, describes sound waves with a frequency below the lower limit of human audibility (generally 20 Hz, as defined by the ANSI/ASA S1.1-2013 standard). [1] Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be ...

  9. Audiogram - Wikipedia

    en.wikipedia.org/wiki/Audiogram

    Audiogram. An audiogram is a graph that shows the audible threshold for standardized frequencies as measured by an audiometer. The Y axis represents intensity measured in decibels (dB) and the X axis represents frequency measured in hertz (Hz). [1] The threshold of hearing is plotted relative to a standardised curve that represents 'normal ...
