Study start date: September 23, 2023

Actual date on which the first participant was enrolled.

The purpose of the current study is to measure oxygenation in the PFC using fNIRS in a sample of older adults with hearing loss. Participants will be instructed to listen to sentences in noise at a challenging signal-to-noise-ratio, and to repeat the word that they heard and rate how much subjective listening effort was required in order to make out the words. fNIRS will be measured throughout. Participants will complete the task using a hearing aid program intended for listening in quiet, and a hearing aid program with new advanced noise management features.

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

26 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Basic Science Study

Basic science studies help researchers understand how the body works or how a disease develops. They don't test treatments, but they build the foundation for future therapies.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Treatment Groups
Study Objectives

2 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Experimental
Participants with hearing loss who are candidates for hearing aids first listen using the device for hearing loss compensation with digital noise management features, followed by the device for hearing loss compensation for listening in quiet environments.

Group II

Experimental
Participants with hearing loss who are candidates for hearing aids first listen using the device for hearing loss compensation for listening in quiet environments, followed by the device for hearing loss compensation with digital noise management features.
