Cochlear sources and otoacoustic emissions.
Current understanding suggests that there are two different mechanisms by which otoacoustic emissions (OAEs) are generated in the cochlea. These mechanisms include a nonlinear-distortion mechanism and a coherent-reflection mechanism. Distortion product OAEs (DPOAEs) are believed to include contributions from both mechanisms, while stimulus frequency OAEs (SFOAES), at least at low and moderate l...
متن کاملCochlear Mechanics and Otoacoustic Emissions
Local, rather than systemic, drug delivery to the inner ear is becoming more widely used to treat inner ear disorders. While many substances are undergoing preclinical and clinical studies, it is equally important to develop appropriate drug delivery systems. Pharmacokinetic studies are technically demanding in animals and almost impossible in humans. Computer simulations have helped establish ...
متن کاملCochlear Mechanics and Otoacoustic Emissions
Background: Congenital malformations of the auricle are often combined with atresia of the outer ear canal and malformations of the ossicles, representing aesthetic as well as functional deficits. Optimal treatment should therefore address both aspects equally. This report describes a new approach, combining the reconstruction of the auricle with implantation of an active middle ear hearing aid...
متن کاملOtoacoustic emissions, their origin in cochlear function, and use.
Otoacoustic emissions (OAEs) are sounds of cochlear origin, which can be recorded by a microphone fitted into the ear canal. They are caused by the motion of the cochlea's sensory hair cells as they energetically respond to auditory stimulation. OAEs provide a simple, efficient and non-invasive objective indicator of healthy cochlear function and OAE screening is widely used in universal new-bo...

To localize low-frequency sound sources in azimuth, the binaural system compares the t iming o f sound waves at the two ears wi th microsecond precision. A similarly high precision is also seen in the binaural processing o f the envelopes of high-frequency complex sounds. Both for lowand high-frequency sounds, interaural time difference ( I T D ) acuity is to a large extent independent o f soun...
