title: Determination of hearing threshold for single frequencies from the acoustic reflex.
abstract: With preactivation, the threshold of stapedial reflex activity can be lowered by 20-30 dB. From these measures of the normal and reduced reflex threshold, an extrapolation may be performed down to the hearing threshold. Thus, the hearing threshold can be determined for every single frequency from 0.125 to 4 kHz if the reflex is elicitable up to 8 kHz.
