Prediction of frequency-specific hearing threshold using chirp auditory brainstem response in infants with hearing losses

Abstract Objectives To investigate the clinical usefulness of the LS-chirp auditory brainstem response for estimation of behavioral thresholds in young children with mild to severe hearing losses. Methods 68 infants (136 ears) aged 6–12 months (mean age = 9.2 months) with bilateral mild to severe he...

Description
Summary:Abstract Objectives To investigate the clinical usefulness of the LS-chirp auditory brainstem response for estimation of behavioral thresholds in young children with mild to severe hearing losses. Methods 68 infants (136 ears) aged 6–12 months (mean age = 9.2 months) with bilateral mild to severe hearing losses were studied at Children's Hospital of Fudan University. In all cases, the children were referred for LS-chirp ABR and visual reinforcement audiometric (VRA) measurements. The low-frequency band chirp (LF-chirp) thresholds (frequency band = 0.1–0.85 kHz) were compared to the average VRA thresholds (frequency band = 0.25–0.5 kHz), whereas the high-frequency band chirp (HF-chirp) thresholds (frequency band = 1–10 kHz) were compared to the average VRA thresholds (frequency band = 1–4 kHz) using statistical correlation coefficient values. Results The LS-chirp ABR thresholds are very close to behavioral hearing levels. The mean differences between chirp-ABR and VRA thresholds were within 5 dB HL for all measurements. The smallest mean threshold difference (
