Abstract [en]

The voice is the most common means of communication and tends to change, sliding up and down the pitch scale when forming phonemes and words, as different emotions and thoughts are expressed. Therefore the ability to discriminate frequencies is of importance for speech intelligibility in a communication situation. Furthermore, this ability is also of importance in speech recognition in noise, by separating the target and noise by spectral and temporal differences of the sources. The choice of rehabilitation is crucial for the frequency discrimination ability. Cochlear implants, for example, lack the ability to pass the temporal fine structure of acoustic waves to the auditory nerve, which in turn lead to reduced precision of phase locking, inferior frequency discrimination ability, and a relatively poor ability to understand speech when background sounds are present.The aim of the study is to investigate how frequency discrimination and temporal resolution abilities interact with performance in speech recognition in noise using a psychoacoustic, speech, and cognitive test battery. These tests will give insight to interactions between performance and hearing status, type of rehabilitation(hearing aid, cochlear implant, and electro-acoustic stimulation), cognitive capacity, and language ability. It is hypothesized that normal hearing participants have a better frequency discrimination ability than hearing impaired participants and by that, better understanding of speech. It is also hypothesized that type of rehabilitation effects performance on frequency discrimination, and that this performance correlates with speech recognition in noise. Finally, it is hypothesized that cognitive capacity and language ability can, to some extent, compensate for loss of frequency resolution in the peripheral auditory system. Preliminary results from the study will be presented and discussed.
