What frequency does feedback occur?

"Whistles" and "screeches" tend to be above 2 kHz. Very rarely does feedback occur below 80 Hz or above 8 kHz. It takes practice to develop an ear for equalizing a sound system, so be patient. After locating the first feedback frequency, begin turning up the system again until the next frequency begins ringing.

What is acoustic frequency?

The audio range falls between 20 Hz and 20,000 Hz. This range is important because its frequencies can be detected by the human ear. This range has a number of applications, including speech communication and music. The ultrasonic range refers to the very high frequencies: 20,000 Hz and higher.

What is acoustic feedback?

noun. : a rumbling, whining, or whistling sound resulting especially from excessive leakage of sound from the output of an electroacoustical system to the input.

Why does acoustic feedback occur?

Acoustic feedback occurs when the amplified sound from any loudspeaker re-enters the sound system through any open microphone and is amplified again and again and again.
