Early Phase 1

Completed

• Conditions: Training Group
• Interventions: Behavioral: training

• Registration Number: NCT04921267
• Lead Sponsor: Kansas State University

Brief Summary

Human listeners will hear speech masked by single-talker speech before and after auditory training.

Detailed Description

Human listeners will hear speech masked by single-talker speech before and after auditory training. Training-related changes in EEG dynamics and behavioral measures of accuracy and effort will be assessed.
