When monkeys are trained to release a response key to the onset of a pure‐tone stimulus, latency of key release is inversely related to tone intensity. Equal values of the behavioral measure (latency) can be said to reflect equal subjective intensities (loudness) and can be used to determine loudness matches. This technique was used to assess the extent of occurrence of loudness recruitment in the presence of noise‐induced TTS and during tone‐on‐tone masking. Under these conditions, latencies measured at lower intensities are lengthened, while latencies at high intensities remain unchanged. When a conductive loss is produced, latencies at all intensities are increased such that the latency‐intensity function appears to be shifted by a constant number of decibels. The data obtained are, in general, consistent with human data on loudness recruitment. Both TTS‐producing exposures and tone‐on‐tone masking result in complete recruitment 20–30 dB above the shifted threshold. With both TTS and masking, overrecruitment is occasionally observed.
