The excitation pattern plots auditory-filter output power against filter center frequency

Evidence

One method of representing sounds to illustrate their internal rather than acoustic representation is the excitation pattern, a representation of the excitation evoked by a sound stimulus plotted as a function of the filter center frequency (Zwicker, 1970). The excitation pattern is essentially a multichannel implementation of the power spectrum model of masking. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 503

• DEFINE: Defines the excitation pattern as the internal (as opposed to acoustic) representation of a sound, built from auditory-filter outputs.
