Background and Objectives: Although ethnicity effect on wideband absorbance (WBA) findingswas evident for adults, its effect on neonates has not been established yet. This studyaimed to investigate the influence of ethnicity on WBA measured at 0 daPa from neonateswith healthy middle ear functions. Subjects and Methods: Participants were 99 normal,healthy, full-term newborn babies with chronological age between 11 and 128 hours of age(mean=46.73, standard deviation=26.36). A cross-sectional study design was used to measureWBA at 16 one-third octave frequency points from 99 neonates comprising of threeethnic groups: Malays (n=58), Chinese (n=13) and Indians (n=28). A total of 165 ears (83.3%)that passed a battery of tests involving distortion product otoacoustic emissions, 1 kHztympanometry and acoustic stapedial reflex were further tested using WBA. Moreover, bodysize measurements were recorded from each participant. Results: The Malays and Indiansneonates showed almost identical WBA response across the frequency range while the Chinesebabies showed lower absorbance values between 1.25 kHz and 5 kHz. However, thedifferences observed in WBA between the three ethnic groups were not statistically significant(p=0.23). Additionally, there were no statistically significant difference in birth weight,height and head circumference among the three ethnic groups. Conclusions: This studyshowed that Malays, Chinese and Indians neonates were not significantly different in their WBAresponses. In conclusion, to apply for the ethnic-specific norms is not warranted when testingneonates from population constitute of these three ethnicities.
