  2. Hearing range - Wikipedia

    en.wikipedia.org/wiki/Hearing_range

    Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies ...

    Key Takeaways: Human hearing spans from 20 Hz to 20,000 Hz. Hearing conversation in noise is challenging, especially when the noise has a similar frequency to human speech.

  4. Audio frequency - Wikipedia

    en.wikipedia.org/wiki/Audio_frequency

    Frequency (Hz) Octave Description 16 to 32 1st The lower human threshold of hearing, and the lowest pedal notes of a pipe organ. 32 to 512 2nd to 5th Rhythm frequencies, where the lower and upper bass notes lie. 512 to 2,048 6th to 7th Defines human speech intelligibility, gives a horn-like or tinny quality to sound. 2,048 to 8,192 8th to 9th

  5. Absolute threshold of hearing - Wikipedia

    en.wikipedia.org/wiki/Absolute_threshold_of_hearing

    The absolute threshold of hearing (ATH), also known as the absolute hearing threshold or auditory threshold, is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the organism.

  6. Infrasound - Wikipedia

    en.wikipedia.org/wiki/Infrasound

    The study of such sound waves is sometimes referred to as infrasonics, covering sounds beneath 20 Hz down to 0.1 Hz (and rarely to 0.001 Hz). People use this frequency range for monitoring earthquakes and volcanoes, charting rock and petroleum formations below the earth, and also in ballistocardiography and seismocardiography to study the ...

  7. Sound - Wikipedia

    en.wikipedia.org/wiki/Sound

    Noise is a term often used to refer to an unwanted sound. In science and engineering, noise is an undesirable component that obscures a wanted signal. However, in sound perception it can often be used to identify the source of a sound and is an important component of timbre perception (see below). Soundscape is the component of the acoustic ...

  8. Psychoacoustics - Wikipedia

    en.wikipedia.org/wiki/Psychoacoustics

    The human ear can nominally hear sounds in the range 20 to 20 000 Hz. The upper limit tends to decrease with age; most adults are unable to hear above 16 000 Hz. The lowest frequency that has been identified as a musical tone is 12 Hz under ideal laboratory conditions. [6] Tones between 4 and 16 Hz can be perceived via the body's sense of touch.
