Purpose: The purpose of this study was to examine test-retest reliability of low-level evoked distortion product otoacoustic emissions (DPOAEs) as a function of L[subscript 1], L[subscript 2] level; f[subscript 2] frequency; and test condition. A predictive relationship between these variables and the presence/absence of DPOAE responses was also…

Simultaneous auditory brainstem responses (ABRs) to click stimuli at 30 and 60 decibels were recorded from 16 full-term neonates with 4 different electrode arrays. Results indicated that ABR waveforms were morphologically similar to those recorded in adults. Waveform expression was variable with different electrode recording montages. (Author/DB)

Simultaneous 3- channel recorded auditory brainstem responses (ABR) were obtained from 20 neonates with various high-pass filter settings and low intensity levels. Results support the advocacy of less restrictive high-pass filtering for neonatal and infant ABR screening to air-conducted and bone-conducted clicks. (Author/JDD)

Variability of aided sound field thresholds (ASFTs) was examined in 30 hearing-impaired children comprising 2 age groups (5-9 and 10-14 years). Findings showed that 2 ASFTs would have to differ by more than 10 decibels across signal test frequencies to attain statistical significance. (Author/DB)
