Gelfand acoustic reflec threshold data

WebAcoustic Reflexes. The acoustic reflex threshold (ART) is the sound pressure level at which the acoustic reflex will be triggered. Ipsilateral and contralateral evaluation of acoustic reflexes is performed to assess the integrity of the acoustic reflex pathway. ARTs are measured at 500 Hz, 1000 Hz, and 2000 Hz. WebAn individual’s acoustic reflex threshold is the lowest elicitor level (dB HL) at which an impedance change is observed and repeatable. Acoustic reflexes have been used …

WebJun 28, 2004 · Average ARTs are about the same for people with normal hearing and sensorineural hearing loss when the pure tone threshold is below 45-50 dBHL (Gelfand et al., 1990). As hearing threshold increases above this point, ART increases. UCL varies with hearing loss in a similar way. WebAcoustic reflex thresholds correctly identified functional losses in 70.9 percent, 78.6 percent, and 85.7 percent of the ears with voluntary thresholds > or = 60 dB HL at one, two, or three of these frequencies, respectively. The false positive rate was only 5 to 7 percent for a control group of 50 ears with genuine sensorineural hearing losses.
