VU And PPM Audio Metering
https://sound-au.com/project55.htm
PPM: A standard PPM has a 5ms integration time, so that only peaks wide enough to be audible are displayed. This translates into a response that is 1dB down from a steady state reading for a 10ms tone burst, 2dB down for a 5ms burst, and 4dB down for a 3 ms burst. These requirements are satisfied by an attack time constant of 1.7ms.

The PPM (Peak Program Meter) is more level orientated and thus works significantly faster than the VU meter. The instrument’s time constant, the integration time, that is, the time it takes the reading to reach a point 2 dB below the reference indication, is 5 ms. In earlier standards the integration time was listed as 10 ms.

Is there a difference between a VU and a PPM audio meter?
https://service.shure.com/s/article/is-there-a-difference-between-a-vu-and-a-ppm-audio-meter?language=en_US
Meters which monitor audio levels are typically one of two varieties: VU (Volume Unit) or PPM (Peak Program Meters). Though both perform the same function, they accomplish the function in very different manners. A VU meter displays the average volume level of an audio signal. A PPM displays the peak volume level of an audio signal.

The Peak Programme Meter or PPM is a much more elaborate design and pre-dates the VU, as its development started in 1932, with the meter we know today appearing in 1938. Despite the name, PPMs don't actually indicate the true peak of the signal voltage.

Peak Metering Digital PPM or Peak Program Meters can help you get a sense of the dynamic range of your mix by displaying the maximum decibel amplitude level of an audio signal’s waveform. Peak metering is designed to respond quickly so that the meter display reacts in exact proportion to the voltage of the audio signal.
