A comparison of the human voice (“Baah”) test and the automated auditory brainstem response in detecting neonates with hearing loss in a community setting

ABSTRACT

Objective@#To assess the usage of the “Baah” Test compared to the AABR (Automated Auditory Brainstem Response) in detecting hearing loss of neonates in the community setting. @*Methods@#This is a retrospective cross-sectional study. The targeted sample population are infants less than a month old who underwent screening at a testing facility in Malolos, Bulacan spanning the years 2011 and 2012. @*Results@#A total of 201 infants were included in the study, with a mean age of 10.77 days with a standard deviation of 7.79. The ratio of males to females was almost equal at 11.01. For infants who passed hearing screening on at least one ear, 96% (193 infants) correlated with the results of “Baah” testing. For those with bilateral refer results on AABR, 4 out of the 6 correlated with the “Baah” Test. @*Conclusion@#There is potential in using the “Baah” Test as a tool for hearing loss assessment of infants in situations wherein the usual hearing screening tests are inaccessible. It makes use of little resources, and though it does have its limitations in assessing for unilateral hearing loss (as the test cannot test ears in isolation), it would be able to identify infants likely to have bilateral hearing loss.
