This systematic review and meta-analysis investigates threshold estimation performance of air-conducted tone-evoked ABR in infants, children, and adults with either typical hearing or sensorineural hearing loss.

Participants with typical hearing, on average, had consistently low ABR thresholds (i.e., approximately 12 to 20 dB nHL).
Findings indicated that tone-evoked ABR threshold (in dB nHL) estimates pure-tone behavioral threshold (in dB HL) in participants with sensorineural hearing loss (SNHL) with good overall accuracy. For individuals with SNHL, ABR threshold is consistently within 10 to 15 dB of the pure tone threshold.
Findings demonstrated that ABR thresholds are, on average, 5.2 to 13.4 dB higher than their pure-tone behavioural thresholds in adults with SNHL.
Findings demonstrated that ABR thresholds are, on average, 5.5 dB above (500 Hz) to 8.1 dB below (4000 Hz) their behavioural pure-tone thresholds for infants and young children with SNHL.
