Interfacing and System Integration - DC Output

The DC output from a sound level meter or noise processor provides a voltage that is proportional to the measured sound level. The voltage usually indicates the "A" weighted Fast sound level, although this can be changed to other weightings with some meters. Being a simple DC voltage that varies linearly with decibels, it can be connected to a monitoring system or used to control a relay or switch.
