The ART was measured with an otoadmittance meter using pure tones (.5, 1, 2, or 4 kc/s) or noise-band (.1-1.6; 1.8-6; .1-6 kc/s) reflex-eliciting signals, on 75 normal Ss and 83 Ss with mild-to-severe sensorineural ... how did the doctor get his name in doctor who

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. People with normal hearing have an acoustic reflex threshold (ART) around 70–100 dB SPL. People with … Ver más 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 Ver más 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; this can be measured thanks to tympanometry. The acoustic stapedius reflex can also be … Ver más • For most animals, the acoustic reflex is the contraction of both middle ear muscles: the stapedius and tensor tympani muscles. However in … Ver más The main hypothesized function of the acoustic reflex is the protection of the organ of Corti against excessive stimulation (especially that of the lower frequencies). This … Ver más • Tensor tympani • Otoacoustic emission • Equal-loudness contours • Audiometry • Hyperacusis Ver más Webat the entrance of the ear canal.
