Signal levels in cochlear implant research are measured as RMS in full-scale decibels.

Evidence

The compressed output envelopes from the STD and MOC strategies were compared for different signals in different types and amounts of noise or interferers (see below). Stimulus levels were expressed as RMS amplitudes in full-scale decibels (dBFS), i.e., dB re the RMS amplitude of a 1-kHz sinusoid with a peak amplitude of 1 (i.e., dB re 0.71). — Dijk, Pim van, Physiology, Psychoacoustics and…, 1957
