简要总结
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.
详细描述
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.

结局指标
主要结局
EEG alpha power measured during Listening Effort Task (LET)
时间窗: 10 weeks
During the LET experiment EEG data will be recorded while participants perform the Adaptive CAtegorical Listening Effort (ACALES). Participants will be equipped with an EEG cap. A continuous EEG will be recorded while participants are performing the LET. Based on the EEG data the alpha power will be analysed offline afterwards.
次要结局
- Working memory measured with Listening Span Task (LST)(10 weeks)
- EEG alpha power measured during Listening Span Task (LST)(10 weeks)
- Listening effort (ACALES) measured during Listening Effort Task (LET)(10 weeks)
