Web21 apr. 2024 · The acoustic middle ear muscle reflex (MEMR) controls the transmission of acoustic signals through the middle ear, while reflex activation of the medial component of the olivocochlear system (the MOCR) modulates cochlear mechanics. The relative prominence of the two efferent systems varies widely between species. Web1 dec. 2024 · The acoustic middle-ear-muscle reflex (MEMR) has been suggested as a sensitive non-invasive measure of cochlear synaptopathy, the loss of synapses between …

WebMiddle ear muscle reflex (MEMR) measurements have been a part of the standard clinical immittance test battery for decades as a cross-check with the behavioral audiogram and … The acoustic reflex (also known as the stapedius reflex, stapedial reflex, auditory reflex, middle-ear-muscle reflex (MEM reflex, MEMR), attenuation reflex, cochleostapedial reflex or intra-aural reflex ) is an involuntary muscle contraction that occurs in the middle ear in response to loud sound … Meer weergeven The acoustic reflex threshold (ART) is the sound pressure level (SPL) from which a sound stimulus with a given frequency will trigger the acoustic reflex. The ART is a function of sound pressure level and frequency. Meer weergeven Most of the time, the stapedius reflex is tested with tympanometry. The contraction of the stapedius muscle stiffens the middle-ear, thus decreasing middle-ear admittance; … Meer weergeven • For most animals, the acoustic reflex is the contraction of both middle ear muscles: the stapedius and tensor tympani muscles. However in humans, the acoustic reflex only … Meer weergeven The main hypothesized function of the acoustic reflex is the protection of the organ of Corti against excessive stimulation … Meer weergeven • Tensor tympani • Otoacoustic emission • Equal-loudness contours • Audiometry • Hyperacusis Meer weergeven som the new school
