Abstract
ABSTRACT The aim of this study was to present basic data on hearing impaired pupils in primary schools in Finland in 1982‐83. The purpose of the survey was to provide an information base for the development of hearing services and teaching in primary schools. Earlier studies have mainly focused on the screening of moderate and severe cases of hearing impairment. The present study includes also cases of mild (20‐30 dB) hearing impairment, the criterion, however, being that hearing impairment in the better ear is > 20 dB in at least one of the three speech frequencies (500‐1000‐2000 hz).
