    en.wikipedia.org/wiki/Colors_of_noise

    The Federal Standard 1037C Telecommunications Glossary [1] [2] defines white, pink, blue, and black noise. The color names for these different types of sounds are derived from a loose analogy between the spectrum of frequencies of sound wave present in the sound (as shown in the blue diagrams) and the equivalent spectrum of light wave frequencies.

  3. Absolute threshold of hearing - Wikipedia

    en.wikipedia.org/wiki/Absolute_threshold_of_hearing

    Auditory sensitivity changes when the duration of a sound becomes less than 1 second. The threshold intensity decreases by about 10 dB when the duration of a tone burst is increased from 20 to 200 ms. For example, suppose that the quietest sound a subject can hear is 16 dB SPL if the sound is presented at a duration of 200 ms.

    In music, dynamic range describes the difference between the quietest and loudest volume of an instrument, part or piece of music. [49] In modern recording, this range is often limited through dynamic range compression , which allows for louder volume, but can make the recording sound less exciting or live.
