    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).

In addition as the receiver is tuned between strong and weak stations, the volume of the sound from the speaker would vary drastically.

    The changing pressure deforms the granules, causing the contact area between each pair of adjacent granules to change, and this causes the electrical resistance of the mass of granules to change. The changes in resistance cause a corresponding change in the current flowing through the microphone, producing the electrical signal.
