The phrase "acoustic reflex" is correct and usable in written English.
It is typically used in the context of audiology and refers to an involuntary muscle contraction in the middle ear in response to loud sounds.
Example: "The audiologist tested the patient's acoustic reflex to assess the functioning of the auditory system."
Alternatives: "stapedius reflex" or "middle ear reflex".
The acoustic reflex (ASR) refers to the reflexive contraction of the middle ear muscles caused by loud sound stimulation.
The full G-EAR study is described elsewhere [ 17], briefly, 3417 subjects within G-EAR aged 18 years or older were recruited from isolated villages in Italy and Croatia and underwent pure-tone audiometry, tympanometry, and acoustic reflex testing in both ears after any acoustically obstructing ear-wax had been removed.
It is thought that a close relationship exists between auditory processing, the acoustic reflex and speech.
Much has been studied on the role of the acoustic reflex in the communication process.
The contraction of the stapedius muscle (that is, acoustic reflex) during overt speech, results in decreased compliance (stiffening) of the middle ear system and attenuation of self-generated vocal sounds.
Different repetition rates were tested in order to determine whether the reaction time of the acoustic reflex influenced its protective effect.
It is likely that toluene might modify the response of protective acoustic reflexes.
Moreover, the rise in CMP magnitude was intensity dependent at this concentration suggesting that toluene could inhibit the auditory efferent system involved in the inner-ear or/and middle-ear acoustic reflexes.
Most of the children in the experimental group had A type tympanogram, and normal acoustic reflexes.
An analysis of ABR latencies of only children who had normal acoustic reflexes was made.
Acoustic reflexes were detected in all OPA1-H patients, whereas they were absent in all but one (Subject 10) of the OPA1-M group.
