    Macs made after 1987 but prior to 1998, upon failing the POST, will immediately halt with a "death chime", which is a sound that varies by model; it can be a simple beep, a car crash sound, the sound of shattering glass, a short musical tone, or more. On the screen, if working, will be the Sad Mac icon, along with two hexadecimal strings, which ...

  5. Beep (sound) - Wikipedia

    en.wikipedia.org/wiki/Beep_(sound)

    A beep is a short, single tone, typically high-pitched, generally made by a computer or other machine.The term has its origin in onomatopoeia.The word "beep-beep" is recorded for the noise of a car horn in 1929, and the modern usage of "beep" for a high-pitched tone is attributed to Arthur C. Clarke in 1951.

  6. Piezoelectric speaker - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_speaker

    A piezoelectric speaker (also known as a piezo bender due to its mode of operation, and sometimes colloquially called a "piezo", buzzer, crystal loudspeaker or beep speaker) is a loudspeaker that uses the piezoelectric effect for generating sound. The initial mechanical motion is created by applying a voltage to a piezoelectric material, and ...

  8. Back-up beeper - Wikipedia

    en.wikipedia.org/wiki/Back-up_beeper

    A white-noise back-up beeper provides a less disruptive alert than the original pure-tone alert. A back-up beeper, also known as back-up alarm or vehicle motion alarm, is a device intended to warn passers-by of a vehicle moving in reverse. Some models produce pure tone beeps at about 1000 Hz and 97-112 decibels. [1]

  9. Noise (electronics) - Wikipedia

    en.wikipedia.org/wiki/Noise_(electronics)

    Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.
