Abstract

Objectives: To investigate whether test age and middle ear dysfunction had a significant effect on the variability of Auditory Steady-State Response (ASSR) thresholds when this test was undertaken on referrals from the newborn hearing screen. Methods: ASSR thresholds were measured at octave intervals from 500 Hz to 4000 Hz. They were recorded in 389 ears with normal hearing and middle ear function, and in a further 189 ears with temporary middle ear dysfunction. The modal corrected age at which the tests were undertaken was four weeks, with a minimum of one week and maximum corrected age of 26 weeks. Results: The mean ASSR thresholds of those with normal hearing were 47dB HL at 500 Hz, 36dB ..
