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.
