Screening of hearing disorders was performed for three-year-old children by using questionnaire, audiometry and tympanometry. The incidence of sensori-neural hearing loss was 0.3%(1 of 288 children) and otitis media with effusion (OME) was 11.5%(33 of them). Audiometry wasnot useful at least for the screening of OME. As to questionnaire, we could select only less than half of OME. It seems necessary to reexamine each content and to find out some adequate items again. Tympanometry was useful for OME especially when it was not detected by other methods. Auditory test by using six whispered words may be helpful to find out moderate or mild hearing loss.
