Extended Frequency Range Cochlear Map

Extended Frequency Range Cochlear Map

Description: Extended frequency range cochlear map testing uses swept-tone stimuli to measure combined distortion product and stimulus-frequency otoacoustic emissions from 1 to 16 kHz, well beyond conventional audiometric ranges. This test provides an extended and nuanced personal map of cochlear output in response to pure tones or pairs of pure tones. Cochlear health and sensory cell integrity are both measured, which may offer information about the nature of the hearing loss — research is currently ongoing to investigate this question.
