Welcome to the Hearing Aid Research Lab (HARL) at the University of Memphis!

The HARL conducts research about the effectiveness of hearing aids for older adults. Founded by Robyn Cox, Ph.D., HARL has a reputation for producing high-quality evidence designed to improve diagnostic and rehabilitative procedures for individuals with hearing impairment. HARL has been under the direction of Jani Johnson, Au.D., Ph.D. since 2016, continuing the traditions of rigorous and clinically-relevant hearing aids research.

The HARL is non-profit. We do not sell or endorse any specific hearing aid manufacturers or products. Although staffed by audiologists and hearing scientists, we do not provide clinical hearing health care services. If you are interested in seeking clinical hearing health services through the Memphis Speech and Hearing Center at the University of Memphis, click here.

This website provides information about who we are and what we do, provides links to our recent publications and to clinical applications developed in our lab, and provides information for those who would like to get involved.

Feel free to contact us and we will get back to you within a few work days. We look forward to hearing from you!
