Summary

In previous studies, Speech Enhancer has been shown to improve Listening Effort using a subjective method. To overcome the weakness of subjective testing, this study uses an objective measurement that has shown convincing results in previous studies addressing Listening Effort.

Detailed description

The Speech Enhancer (SE) provides better speech intelligibility for soft speech while maintaining the same sound quality for loud input level. Better speech intelligibility may also result in less listening effort in some circumstances. So there was the hope that the SE provides better speech intelligibility and less listening effort for situation with soft speech. The SE has already been intensely and successfully investigated in early studies. The cognitive performance on a neurophiosiological level has already been successfully investigated in a previous studies.
