Trial Summary

What is the purpose of this trial?

New discoveries for hearing loss intervention are often impeded by the proprietary nature of commercial hearing aids and their use in scientific research as "black boxes". An open-source speech platform (OSP) was developed to bridge the gap between audiology research and commercial hearing aid features, to promote innovative solutions to meet the needs of the hearing loss community. The OSP can replicate functions found in commercial hearing aids, and provides tools to researchers to access those functions. The purpose of this study is to evaluate portable and cloud-based platforms of the OSP that will enable a wide range of lab and field applications. All human subjects-related activities will be conducted at Northwestern University (single-site study).

Eligibility Criteria

This trial is for adults over 18 with sensorineural hearing loss, who speak English as their primary language and have normal or corrected vision. They should be in good health overall. People with unstable medical conditions, cognitive impairment (scoring below 23 on a specific test), conductive hearing loss, or significant ear/neurological disorders cannot participate.

Inclusion Criteria

I am 18 years old or older.

I have hearing loss within a specific range.

My vision is normal or corrected to normal.

Exclusion Criteria

You have a history of ear or brain disorders that are important.

I have hearing loss or problems with my middle ear.

You scored lower than 23 on a test that checks how well you can think and remember things.

Treatment Details

Interventions

• Cloud-based OSP
• Portable OSP

Trial Overview The study is testing two versions of an open-source speech platform (OSP) designed to improve research into hearing aids: one that's portable and another that's cloud-based. The goal is to see how these platforms can support lab and field work in audiology research at Northwestern University.

Participant Groups

Group I: Portable OSP Experimental Treatment 1 Intervention

Outcomes will be assessed with the portable version of the OSP.

Group II: Cloud-based OSP Experimental Treatment 1 Intervention

Outcomes will be assessed with the cloud-based version of the OSP.
