VU meters and PPMs also differ in terms of acceleration and deceleration rates (ballistics). The difference between the reading of a VU meter and a PPM is called the crest factor. VU meters display the average volume level of an audio signal whereas PPMs display peak volume. Note: a power level (i.e., amount of energy transferred per unit of time Unit is Watt) of 0dBm corresponds to a power of 1 mW In practice, however, VU meters contain an isolating resistor so that 0 VU equals +4 dBm (power of about 2.5mW applied across a 600-ohm load) for a pure sine wave (see Engineering 360). For a pure 100-Hz sine wave, 0 VU equals 0 dBm or 0.775V root means square (RMS see my post about Decibels). Readings on the VU scale are approximate to the base 10 of the power ratio referenced to that level. If a constant sine-wave of 0 VU is applied, the meter will achieve 0 VU in 300 ms. Most VU meters have a scale from -20 to +3, and rise and fall times of 300 milliseconds (ms). By definition, a reading of 0 VU describes a 600-ohm resistance in which 1 milliwatt (mW) of sine-wave power (see my post about Sound Waves) flows at 1kHz. VU meters display signal levels in volume units (VU), a measure of average volume level. For a nice video about gain staging using VU meters see. One use of the VU meter is gain staging which I do not discuss here. The Acoustical Society of America standardized it in 1942 (ANSI C16.5-1942 Wikipedia). The VU meter is sometimes also denoted as ‘standard volume indicator’. The volume unit (VU) meter measures the volume of audio levels in digital audio workstations (DAWs) like Cubase or other (hardware) devices.
