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.

WebAbstract The acoustic reflex threshold (ART) was studied in 544 ears having hearing levels (ANSI-1969) ranging from 0 to 110 dB HL. The activating signals were pure tones (500, 1000, and 2000 Hz) presented at levels up to 125 dB HL. The results indicated that the ART increased with hearing loss beyond certain levels. Web10 de feb. de 2024 · The acoustic reflex is the contraction of the stapedius muscle elicited by the presentation of an acoustically loud sound. When either ear is presented with a loud sound, the stapedius muscles on both sides contract. Contraction of the stapedius muscle tilts the anterior stapes away from the oval window and stiffens the ossicular chain.

WebAcoustic reflexes serve as a very useful diagnostic tool in the assessment of middle ear function. True middle ear pathology typically results in absent acoustic reflexes, but … WebThe middle ear muscles contract in response to loud sounds, and this reflex can be measured as part of the hearing assessment.
