Click-evoked otoacoustic emissions (CEOAEs) are clinically used as an objective way to infer whether cochlear functions normal. However, because the sound pressure level of CEOAEs is typically much lower than background noise, it usually takes hundreds, if not thousands repetitions estimate signal with sufficient accuracy. In this paper, we propose improve signal-to-noise ratio (SNR) CEOAE sign...

Reliable estimates of supra-threshold (60-80 dB SPL) filter tuning are necessary to understand auditory processing of speech. However, existing approaches suffer from methodological limitations that require high suppressor tone levels (psychoacoustics) or an assumption of linearity (otoacoustic emission group delay) to estimate human auditory filter tuning at higher stimulus levels. We propose ...

Bone conduction is being utilized widely for music reproduction and hearing aids. However, due to unclear transmitting process of bone conduction, some detailed characteristics are still in discussion. Previous researchers has made achievements on frequency characteristics of bone conduction actuators by comparing the relationship between loudness as a subjective measurement and acceleration as...

This paper tests key predictions of the "two-mechanism model" for the generation of distortion-product otoacoustic emissions (DPOAEs). The two-mechanism model asserts that lower-sideband DPOAEs constitute a mixture of emissions arising not simply from two distinct cochlear locations (as is now well established) but, more importantly, by two fundamentally different mechanisms: nonlinear distorti...
