Speech Understanding and Listening Effort Benefits of Hearing Instruments
This study is looking at how different hearing instruments (hearing aids) can help adults with hearing loss better understand speech and reduce the effort it takes to listen. Researchers will compare three different models of hearing instruments to see their impact. To join, you must be 18-95 years old, have N3 or N4 hearing loss, already use hearing aids, and be fluent in English. The main goal is to measure how well you understand speech using a test called the Coordinate Response Measure (CRM) Task. The current status of this study is unclear.
- Study design
- This is an interventional study planning to enroll 30 participants. It will compare three different models of hearing instruments.
- What's involved
- You will wear different hearing instruments and participate in lab-based activities to evaluate your speech understanding, listening effort, and preferences. Data is collected during a 2.5-hour lab visit, approximately 2 weeks after enrollment.
- Compensation
- Not stated in the trial record.
- Follow-up
- Not specified.

What this trial measures
- Speech intelligibility as assessed by the Coordinate Response Measure (CRM) TaskData is collected during the second lab visit for each participant, approximately 2 weeks after study enrollment. The duration of the study visit including testing is approximately 2.5 hours.
During the CRM task (Bolia et al., 2000), participants are presented with a phrase detailing the following identifiers: target, color, and digit. They must listen for a target name and respond with the corresponding color and digit. Speech intelligibility performance is assessed based on accuracy, or percent correct across all trials conducted in a given condition.
