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. 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.
