“…This would provide additional information on the effects of maturation on the ASSR provided by Rance and Tomlin [2006] by also including data for the preterm periods. Further data should also be sought to explore the effect of hearing loss on the maturation of the ASSR response [Rance et al, 1998;Johnson and Brown, 2005;Rance, 2008]. This would determine whether the maturation of the ASSR response is similar with cases of sensorineural hearing loss and whether the same correlation could potentially be observed between ASSR and behavioral thresholds for both normal-hearing and hearing-impaired neonates.…”

Hearing thresholds were estimated in normal-hearing term and preterm neonates of <35 weeks of age using multiple-stimulus auditory steady-state responses (ASSRs). The tresholds, expressed in decibel sound pressure level, at signal frequencies of 500, 1000, 2000 and 4000 Hz were 44.30 ± 9.88, 27.80 ± 6.79, 26.77 ± 6.09 and 32.87 ± 6.12 for the term group and 49.11 ± 9.44, 26.38 ± 6.59, 26.74 ± 7.57 and 35.90 ± 8.23 for the preterm group. Significant threshold differences were measured between the groups at 500 and 4000 Hz, while the thresholds at 1000 and 2000 Hz were similar. The signal and noise levels as well as signal-to-noise ratio of responses were also measured and found to be similar. These results indicate that ASSRs can be effectively measured with a similar signal-to-noise ratio in both groups, but that there is a significant maturational effect occurring during gestation at the level of structures which participate in the formation of the ASSR at 500 and 4000 Hz.

“…Reports have demonstrated significant correlations between ASSR, behavioural and ABR thresholds across various age groups including adults and children [1,3,4,9]. Despite good correlations there are significant differences between studies reporting ranges of ASSR and behavioural threshold difference from 4 to 34 dB [2,6].…”

KEYWORDSAuditory steady-state response, objective frequency-specific audiometry, sensorineural hearing loss, ABSTRACTThe Auditory Steady-State Response (ASSR) has gained popularity as an alternative technique for objective audiometry but its use in less severe degrees of hearing loss has been questioned. The aim of this study was to investigate the usefulness of the ASSR in estimating moderate degrees of hearing loss. Seven subjects (12 ears) with moderate sensorineural hearing loss between 15 and 18 years of ages were enrolled in the study. 48 behavioural and ASSR thresholds were obtained across the frequencies of 0.5, 1, 2, and 4 kHz. ASSR thresholds were determined using a dichotic multiple frequency recording technique. Mean threshold differences varied between 2 and 8 dB (±7-10 dB SD) across frequencies. The highest difference and variability was recorded at 0.5 kHz. The frequencies 1 -4 kHz also revealed significantly better correlations (0.74 -0.88) compared to 0.5 kHz (0.31). Comparing correlation coefficients for behavioural thresholds less than 60 dB and 60 dB and higher revealed a significant difference. 86% of ASSR thresholds corresponded within 5 dB of moderate to severe behavioural thresholds compared to only 29% for mild to moderate thresholds in this study. The results confirm that the ASSR can reliably estimated behavioural thresholds of 60 dB and higher, but due to increased variability caution is recommended when estimating behavioural thresholds of less than 60 dB, especially at 0.5 kHz.

“…These data concur with other published results 11,20,23,26 . Very few studies have compared thresholds measured with tone burst ABR and ASSR in the same population 6,15,17,19,27 . The choice of two measurements of test duration was made to observe the true clinical application of these tools.…”

Accurat e information about type, degree, and configuration of hearing loss are necessary for successful audiological early interventions. Auditory brainstem response with tone burst stimuli (TB ABR) and auditory steady-state response (ASSR) exams provide this information. Aim:To analyze the clinical applicability of TB ABR and ASSR at 2 kHz in infants, comparing responses in full-term and premature neonates. Material and Method:The study was cross-sectional, clinical and experimental. Subjects consisted of 17 premature infants and 19 full-term infants. TB ABR and ASSR exams at 2000 Hz were done during natural sleep. Results:The electrophysiological minimum response obtained with TB ABR was 32.4 dBnHL (52.4 dBSPL); the ASSR minimum was 13.8 dBHL (26.4 dBSPL). The exams required 21.1 min and 22 min, respectively. Premature and full-term infant responses showed no statistically significant differences, except for auditory steady-state response duration. Conclusions:Both exams have clinical applicability at 2 kHz in infants, with 20 min of duration, on average. In general, there are no differences between premature and full-term individuals.
