Critical-band rate and excitation level are the intermediate transforms for hearing models

Evidence

A comparison between the top drawings in Fig. 6.13 with the bottom drawings indicates how the characteristics of the hearing system, expressed by critical-band rate and excitation level, transform the physical values into intermediate values more meaningful for the development of models for psychoacoustical perception. — Professor Dr.-Ing.

• DEFINE: This locates the theoretical role of critical-band rate and excitation level as model-ready intermediate representations sitting between physical stimulus and percept.
