简要总结
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.

结局指标
主要结局
Speech intelligibility as assessed by the Coordinate Response Measure (CRM) Task
时间窗: 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.
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.
次要结局
- Listening Effort as assessed by the Adaptive Categorical Listening Effort Scaling (ACALES)(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.)
