Using click-evoked auditory brainstem response thresholds in infants to estimate the corresponding pure-tone audiometry thresholds in children referred from UNHS.

To examine whether behavioral pure-tone audiometry (PTA) thresholds in children can be accurately estimated from the corresponding infants' click-evoked auditory brainstem response (ABR) thresholds through a retrospective review of data from a universal newborn hearing screening (UNHS) program in Taiwan. According to medical records from Mackay Memorial Hospital, Taipei Hospital District, 45,450 newborns received hearing screening during January 1999-December 2011. Among these newborns, 104 (82, both ears; 22, one ear; total, 186 ears) received regular follow-up and were recruited as subjects. The relationship between infant click-evoked ABR thresholds and the corresponding child PTA thresholds was determined through Pearson correlation coefficient and linear regression analyses. The correlation coefficient between click-evoked ABR thresholds and behavioral PTA thresholds at the average of frequencies of 1-4 and 2-4 kHz was 0.76 and 0.76, respectively. Linear regression analysis showed that behavioral audiometry thresholds at the average of frequencies of 1-4 and 2-4 kHz were accurately estimated from click-evoked ABR thresholds in 57% and 58% children, respectively. Click-evoked ABR testing is a reliable tool to cautiously estimate behavioral PTA thresholds at the average of frequencies of 1-4 and 2-4 kHz. For accurately performing hearing aid fitting and auditory rehabilitation in congenitally deaf infants, a combination of frequency-specific tone-burst ABR and click-evoked ABR should be used.

Prediction of the pure-tone average from the speech reception and auditory brainstem response thresholds in a geriatric population.

Although the pure-tone average (PTA) remains the standard assessment of hearing status, its results are questionable in the difficult-to-test geriatric population. In this study, we assessed the relationship between the 4-frequency PTA, speech reception threshold (SRT) and auditory brainstem response (ABR) threshold in the aged. We developed an equation as a tool to predict the actual PTA. Forty-six subjects more than 60 years of age were consecutively enrolled in the study. All subjects underwent hearing threshold evaluation by means of PTA, SRT and ABR testing on both ears. Using simple linear and multiple regressions, the correlation and multiple regression models between PTA, SRT and ABR thresholds were calculated. The Pearson correlation coefficient between pure-tone thresholds (PTTs) and SRT was highest at 0.5-2 kHz (r = 0.948). The Pearson correlation coefficient between PTTs and ABR thresholds was highest at 2-4 kHz (r = 0.690). The resultant multiple regression model to predict actual PTA was: PTA = 3.274 + 0.774 (SRT) + 0.245 (ABR). In this study, we delineated the relationship between the PTA, SRT and ABR threshold, and established an equation to predict the actual PTA from the SRT and ABR threshold in difficult-to-test patients, allowing accurate assessment of the hearing threshold in geriatric populations.
