This thesis compared the loudness discomfort levels (LDL) for a group of normal hearing children to those for a group of children with sensori-neural hearing losses. The children with a loss were students at a school for the deaf. The LDL’s for the frequencies 250, 500, 1000, 2000, and 4000 Hz and for speech were obtained.It was found that the sensori-neural loss group had higher LDL’s for both pure tones and speech than the normal hearers. It was further found that for the normal hearers, the LDL’s were higher for speech than for the average of the pure tone speech frequencies. The results of this study were also higher than previous researchers had found. The possible reasons for the differences between the groups and between the results of this study and previous ones were discussed.
