Applied Sciences, 2019 Distortion-product otoacoustic emissions (DPOAEs) elicited with high-frequency (HF; up to 16 kHz) stimuli are measurable and repeatable in normal-hearing adults and children, adult patients, and are sensitive to ototoxic insults in adults.

Evaluation of Hearing and Outer Hair Cell Function of Cochlea in Patients With Psoriatic Arthritis [PDF]
Clinical and Experimental Otorhinolaryngology, 2015 ObjectivesThe aim of this study was to investigate hearing and outer cells function in patients with psoriatic arthritis. Our investigation was a prospective case control study.MethodsA total of 31 psoriatic arthritis patients (62 ears) and 31 healthy ...

The Auditory Nerve Overlapped Waveform (ANOW) detects small endolymphatic manipulations that may go undetected by conventional measurements [PDF]
, 2017 Electrocochleography (ECochG) has been used to assess Ménière's disease, a pathology associated with endolymphatic hydrops and low-frequency sensorineural hearing loss. However, the current ECochG techniques are limited for use at high-frequencies only (≥

Individual differences in auditory brainstem response wave characteristics : relations to different aspects of peripheral hearing loss [PDF]
, 2016 Little is known about how outer hair cell loss interacts with noise-induced and age-related auditory nerve degradation (i.e., cochlear synaptopathy) to affect auditory brainstem response (ABR) wave characteristics.

Wireless earbuds for low-cost hearing screening [PDF]
arXiv, 2022 We present the first wireless earbud hardware that can perform hearing screening by detecting otoacoustic emissions. The conventional wisdom has been that detecting otoacoustic emissions, which are the faint sounds generated by the cochlea, requires sensitive and expensive acoustic hardware. Thus, medical devices for hearing screening cost thousands of

Denoising Click-evoked Otoacoustic Emission Signals by Optimal Shrinkage [PDF]
, 2020 Click-evoked otoacoustic emissions (CEOAEs) are clinically used as an objective way to infer whether cochlear functions are normal. However, because the sound pressure level of CEOAEs is typically much lower than the background noise, it usually takes hundreds, if not thousands of repetitions to estimate the signal with sufficient accuracy.

Spatial Coherence of Light in Collective Spontaneous Emission [PDF]
, 2021 When a quantum system is put into an excited state, it will decay back to the ground state through a process termed spontaneous emission. It is generally assumed that spontaneous emission between different individual emitters would not be coherent with each other; to produce coherent light one would need population inversion and stimulated emission. In

A study on the lateralization of the effect of musical imagery on spontaneous otoacoustic emissions [PDF]
, 2007 It has been suggested that different pathways through the brain are followed depending on the type of information that is being processed. Although it is now known that there is a continuous exchange of information through both hemispheres, language is ...

The 1.06 frequency ratio in the cochlea: evidence and outlook for a natural musical semitone [PDF]
PeerJ, 2017 A frequency ratio of about 1.06 often appears in cochlear mechanics, and the question naturally arises, why? The ratio is close to that of the semitone (1.059) in music, giving reason to think that this aspect of musical perception might have a cochlear ...

Frontiers in Molecular Neuroscience, 2019 CEACAM16 is a non-collagenous protein of the tectorial membrane, an extracellular structure of the cochlea essential for normal hearing. Dominant and recessive mutations in CEACAM16 have been reported to cause postlingual and progressive forms of ...
