Postmasking temporal decay is realizable by a two-resistor two-capacitor diode network

Evidence

This behaviour can be simulated by a relatively simple network, which contains two resistors, two capacitors and a diode. Its input is specific loudness derived directly from the instantaneous direct excitation, i.e. the level within the critical band in question. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
