Block diagram of the signal-flow for a common feedback loop [1]: 118 . Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio output (for example, a loudspeaker) and its audio input (for example, a microphone or guitar pickup).
NOAA's Christopher Fox did not believe its origin was man-made, such as a submarine or bomb. While the audio profile of Bloop does resemble that of a living creature, [ 4 ] the source was a mystery both because it was different from known sounds and because it was several times louder than the loudest recorded animal, the blue whale .

Traumatic noise exposure can happen at work (e.g., loud machinery), at play (e.g., loud sporting events, concerts, recreational activities), and/or by accident (e.g., a backfiring engine.) Noise induced hearing loss is sometimes unilateral and typically causes patients to lose hearing around the frequency of the triggering sound trauma. [17]

While noise music is often nowadays associated with extreme volume and distortion [95] and produced by electronic amplification, the tradition dates back at least to the Futurist Luigi Russolo, [96] who rejected melody, constructed original instruments known as intonarumori and assembled a "noise orchestra" in 1917. It was not well received. [97]
When sensorineural hearing loss (damage to the cochlea or in the brain) is present, the perception of loudness is altered. Sounds at low levels (often perceived by those without hearing loss as relatively quiet) are no longer audible to the hearing impaired, but sounds at high levels often are perceived as having the same loudness as they would for an unimpaired listener.
