Abstract
OBJECTIVE: To analyze acoustic absorbance using wideband tympanometry in neonates exposed to passive smoking during pregnancy. METHOD: A study comprising 54 neonates in the control group (CG - unexposed) and 19 in the study group (SG - exposed) was carried out. Subjects were submitted to the wideband tympanometry test and subsequent analysis of absorbance of 17 frequencies. RESULT: Low frequencies had a lower level of absorbance compared to high frequencies for both ambient and peak pressures, with no difference between the groups. CONCLUSION: No effect of passive smoking on acoustic absorbance measurements in neonates was observed.
