On February 21, Alan Wiinberg successfully defended his PhD thesisPerceptual effects of non-linear hearing aid amplification strategies".

One of the most common reported complaints from people with sensorineural hearing loss is difficulties in understanding speech in complex acoustic environments. Some of these difficulties are caused by loss of cochlear compression, which results in reduced sensitivity to soft sounds, steeper loudness growth, and altered temporal resolution compared to normal-hearing people. In an attempt to compensate for the loss of cochlear compression, many modern hearing aids use a compressive amplification strategy. However, while speech perception might be improved by hearing-aid compression, the provided level-dependent amplification may lead to undesired distortions of the binaural cues which are essential for spatial perception.

In his thesis, Alan Wiinberg conducted several studies to investigate the effects of non-linear hearing-aid amplification strategies on hearing-impaired listeners’ spatial perception, temporal resolution, and speech perception. Overall, it is expected that the outcomes of this thesis will influence the development of future hearing-aid signal processing strategies and improve the quality of life of hearing-aid users.
