[A preliminary study on wideband acoustic immittance of infants with normal bilateral middle ear function at the age of 1-5 months].
Objective:To explore preliminary characteristics of wideband acoustic immittance of 1- to 5-month-old infants who have bilateral normal middle ear function, so as to contribute to the clinical application of WAI test in the evaluation of middle ear function in infants. Methods:1- to 5-month-old infants were included. After the normal function of bilateral middle ear was determined by otoacoustic emission and high frequency acoustic immittance test, WAI test was performed and the relevant data were collected and analyzed. Results:There was no statistical difference in absorbance at the same frequency between the left ear and right ear of each group(P>0.05). Absorbance of 4000 Hz increased at first and then decreased with the growth of physiological age, and the sound energy absorption rate of other frequencies decreased except 2670 Hz and 3364 Hz. Conclusion:The outcome of this study shows that it is necessary to establish the national normal value of WAI in 1- to 5-month-old infants who have bilateral normal middle ear function. The purpose of the development of middle ear system is to ensure that sounds in the speech frequency range can be transmitted and heard more effectively.
