Abstract

Recent advancement in digital hearing aids has the flexibility to restore the lost compressive nonlinearity of cochlea by compression circuits. The current study is aimed at studying the loudness growth functions in normal hearing and hearing impaired adults those who use compression hearing aids. Categorical loudness scaling was assessed in both the normal hearing and hearing impaired adults with hearing aid. There frequencies were tested viz. 500 Hz, 1000 Hz and 2000 Hz. The hearing aid programme was held constant (NAL-NL1) across participants. The results revealed a significant main effect of group on loudness growth function; where the loudness growth grew steeper for low to moderately intense sounds in hearing impaired than for normal hearers. This implies, the differences in loudness growth function persist in hearing impaired even after fitting with an appropriate compression hearing aids.
