The effect of noise-induced hearing loss on the perception of Dutch consonants in different types of noise
In this study the effect of noise-induced hearing loss on Dutch consonant perception in different types of background noise is investigated. There is quite a lot of research about consonant perception in background noise and also some on that topic with hearing-impaired participants, but no research has been done on noise-induced hearing loss, which is an interesting type of hearing loss in this particular field of study, because of its spectral frequency properties. In this experiment 10 normal hearing people and three hearing-impaired people of ages 25 - 39 listened to 24 consonants in a clean condition and in three noise type conditions: a competing speaker, modulated speech-shaped noise and speech-shaped noise. There is no difference in performance of consonant identification between normal hearing and hearing-impaired people. The effect of noise type was significant, with modulated speech-shaped noise being the most difficult and competing speaker the easiest condition for consonant.
