Summary:A hypothesis is offered to account for the fact that in functional hearing loss, spondee threshold is frequently significantly lower than the pure-tone average. The hypothesis has three basic components: (1) that patients with functional hearing loss use a loudness criterion in making response decisions to suprathreshold stimuli; (2) that, at suprathreshold levels, pure tones and spondee words appear equally loud at equal sound pressure levels, and (3) that calibration values employed in pure-tone and speech audiometry contribute to the aberrant speech-pure tone relationship. Factors that may confound the speech-pure tone relationship are discussed as are the clinical and research implication of the hypothesis.
