Spontaneous otoacoustic emissions enable least-invasive monitoring of inner ear function
Evidence
The current biophysical experiments reveal a significant effect of LF sound exposure on the inner ear, and specifically on the function of OHCs. The observed effects are reflected in significant changes of quadratic distortion products, but importantly, in changes of SOAEs, which (for the ears that exhibit them) allows for a least-invasive evaluation of inner ear function. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3745
