Area of Science:

Neuroscience
Audiology
Hearing Science

Background:

Hearing aid directivity aims to improve speech-in-noise (SiN) perception.
Multistream architecture (MSA) is a hearing aid technology designed to enhance directional hearing.
Alpha-band neural activity is often associated with cognitive load and task difficulty.

Purpose of the Study:

To investigate if hearing aid directivity via MSA reduces alpha-band electroencephalographic (EEG) activity, indicating reduced listening effort.
To correlate behavioral SiN benefits with neural activity changes.

Main Methods:

A within-subject, single-blind study with 13 older adults with hearing loss.
Participants performed a SiN test with hearing aids in MSA-ON and MSA-OFF conditions.
EEG was recorded to measure alpha-band oscillations during the SiN tasks.

Main Results:

Alpha-band activity was significantly reduced over centroparietal sites in the MSA-ON condition compared to MSA-OFF.
Alpha-band power increased over trials, suggesting potential listener fatigue.
Reductions in alpha-band power did not significantly correlate with behavioral SiN improvements.

Conclusions:

MSA hearing aid directivity lowers neural activity associated with listening difficulty in simulated multitalker scenarios.
Alpha-band EEG may serve as a valuable tool for assessing the impact of hearing aid processing on listening effort.
Further research is needed to understand the relationship between neural changes and individual behavioral benefits.
