title: Vasomotor response to pure tones using photoplethysmography.
abstract: Digital photoplethysmography has been applied to the determination of hearing levels for pure tones. On average, the levels established were some 30 dB higher than those obtained with conventional pure-tone audiometry. Intervals between stimuli, however, were shown to have a significant effect upon the responses and the evidence suggests that recovery periods of 5 min may be required to obtain stable responses. The resulting testing tone involved is probably too long for most practical purposes.
