Abstract

To explore the extent of distortion product otoacoustic emission (DPOAE) toward low frequencies we measured in 21 normal-hearing human subjects its dependence on the ratio between evoking stimulus frequencies, f1 and f2, at 2f1-f2 distortion frequencies 88, 176, and 264 Hz. The “optimal” ratio evoking the largest DPOAE level is frequency dependent but well-guided by 1.52 equivalent rectangular bandwidth (ERB).
