VU (band abbreviation)

VU stands for "Volume Unit" and is a measure used in audio to gauge the perceived loudness of sound signals. When you see VU meters on audio equipment, they indicate how loud the audio signal is reaching. The VU scale helps audio engineers balance sound levels, ensuring recordings or broadcasts are neither too soft nor too loud, preventing distortion or loss of quality. It’s a standardized way to monitor loudness and maintain consistent audio levels across different devices or recordings.
