The goal of this clinical study is to investigate the benefits of hearing instrument use in adults with hearing loss. The main questions it aims to answer are:
Does hearing instrument use improve speech understanding and listening effort amount people with hearing loss? Researchers will compare varying models of hearing instruments to see how speech understanding and listening effort are impacted.
Participants will be asked to wearing varying hearing instruments and participate in lab-based activities to evaluate their speech understanding, listening effort, and subjective preference.

| Measure | Description | Time Frame |
|---|---|---|
| Speech intelligibility as assessed by the Coordinate Response Measure (CRM) Task | 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. | Data 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Listening Effort as assessed by the Adaptive Categorical Listening Effort Scaling (ACALES) | The ACALES is an adaptive measure of listening effort where the target and interfering background signals are adapted according to participant feedback. Following the target presentation, participants rate listening effort on a 14-point scale | Data 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Hearing Instrument Device Preference Questionnaire | Participants are asked to subjectively rate elements of sound quality and overall preference of the devices under test following standardized presentation of speech-in-noise stimuli in the lab environment. | Data 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. |
