Recently in Korea, there is increasing interest in hearing impaired children and hearing aids. However, some of the physicians, most of the hearing aid dealers and hearing aid users lack the awareness of the intricacy of appropriate selection and method of use, which can lead to significant hazard in hearing, dissatisfaction, economic loss and so on. For these reasons, the authors planned to study on the attitude towards, recent trends and status of hearing aid use. This study is divided into two parts. Part I dealt with analysis on the questionaires obtained from 487 hearing impaired children of 3 special schools in Seoul. Part II will deal with analysis of the electroacoustic characteristics of the hearing aids as worn by the children. The results of Part I were as follows : 1) 91.8% of the 487 answerers wore hearing aids. The rate of the wearers were greater in younger children. 2) The mean age when the first audiometry was administered was 3.9 years and the mean age of the first hearing aid purchase was 5.0 years. 3) Pocket aids were 88.7% and the rest were behind-the-ear aids. 4) 91.9% of the wearers received some type of benefit from the hearing aids. The rate of the benefit received in communication was greater in younger children than in the older children and the rate of the benefit received in daily life other than in communication were greater in older children. 5) 97.1% of the wearers used custom-made earmolds. 6) 78.6% of the wearers were full time users. More of the younger children were full time users than the older children. 7) The mean life spans of hearing aids and of cords of the pocket aids were 3.7 years and 7.8 months, respectively. 8) Only 18.5% of the wearers controlled their volumes appropriately according to the different environmental noise.
