To assess the ability of pulmonary function and the relationship between the degrees of hearing defect and breathing capacities, we measured the flow-volume curves of 32 deaf children in middle school for the deaf, and of 88 normal children in junior high school with the use of flow volume reader manufactured with Nihonkoden's MFR-8100. And we also investigated the height of all subjects and the values of hearing loss in deaf children. After that, we treated the obtained data statistically. The results are summarized as follows: (1) The correlation coefficient between breathing capacities of deaf children and their heights was r=0.798 in school boys, and r=0.837 in school girls. (2) The average capacity of lungs of the children from the 1 grade to the 3 grade in lower secondary school was 3.11l in male, 2.58l in female in the study area, and 3.04l in male, 2.43l in female in the control area. (3) The itsms of the breathing function test were VC, %VC, FVC, FVC1.0, FEV1.0, FEV1.0%, Index, V75/HT, V50/HT, V25/HT, V10/HT, V50/V25, &V25/V10, and they are not significantly for the two areas in both sexes, but except V75/HT in female was higher in the study area than in the control areas. (4) The correlation coefficient between the total mean values of average hearing loss in both ears and all the mean values of their lung capacity was r=-0.145 in male, and r=0.397 in female.
