Morphology

squelcher = squelch (semi-transparent) = squelch + er

The device's function (to suppress or mute audio) follows directly from 'squelch' + '-er', but the specific technical sense 'electronic circuit' is specialized and not fully inferable by all learners.

Etymology

Squelcher comes from the verb squelch, a sound word that grew to mean 'stop' or 'silence' unwanted noise. In electronics, a squelcher is a circuit that 'stops' weak signals or background noise so you hear only the clear sound.
