In telecommunications, a psophometer is an instrument that provides a visual indication of the audible effects of disturbing voltages of various frequencies.

A psophometer usually incorporates a weighting network. The characteristics of the weighting network depend on the type of circuit under investigation, such as whether the circuit is used for high-fidelity music or for normal speech.
