PURPOSE:
to describe
the results of the pilot study carried out to guide the implementation process of the hearing screening in schools in the City of Porto Alegre.
METHODS:
134 protocols were applied to children between the ages of six and eight, from a Municipal Elementary School in Porto Alegre. The results presented in the screening protocol were: the measurement of the Sound Pressure Level in the environment during the audiometric screening; response to audiometric screening at 20 dB with frequencies of 1000Hz, 2000Hz and 4000Hz in both ears; Acoustic Immittance Measures: tympanometric curve and ipsilateral acoustic reflexes at the frequencies of 500Hz, 1000Hz, 2000Hz and 4000Hz, at 100 dB in both ears, using the pass-fail criterion.
RESULTS:
in relation to sex, 50.75% were boys. The average age was 6.86 (±0.46). Most children passed the audiometric screening and the most frequent tympanometric curve was Type A (51.7 %), followed by Type C (24.1 %) in the right ear. In the left ear, 55.7% were Type A and 21.6%, Type C. The environmental noise remained below 50dBSPL in 90.5%.
CONCLUSION:
the majority of children who failed the audiometric screening were six years old. The most prevalent tympanometric curve was Type A, followed by Type C. No statistically significant differences were observed when genders and tested ears were compared.
