Speech Understanding and Listening Effort Benefits of Infinio Sphere
Overview
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.
Interventions
- Device hearing instruments
Participants will be fit with three different models of hearing instruments.
Primary outcome measures
- Speech intelligibility as assessed by the Coordinate Response Measure (CRM) Task [Time frame: 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.]
Secondary outcome measures (1)
- Listening Effort as assessed by the Adaptive Categorical Listening Effort Scaling (ACALES) [Time frame: 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.]
