In the Hearing Research Lab, researchers study the effects of hearing loss in children and adults as well as aspects of normal hearing development. Currently, researchers are pursuing three areas of research: spatial listening and learning, hearing aids and other hearing technologies, and the development of new tests for hearing loss intervention. The goal is to assist audiologists in the care and management of their patients.
 

Current Research

Spatial Listening and Learning in Children with Hearing Loss

Our research investigates the effect of hearing loss on spatial listening and learning in children. The current study aims to quantify left-and-right-ear differences in children with hearing loss relative to their normally hearing peers. Participants include young adults with normal hearing as well as older children with normal hearing and children who use, or could benefit from, hearing aids. Results from the study will reveal hearing aid fitting strategies that may improve spatial listening for children with hearing loss. This project is funded by a grant from the William Demant Foundation.
 

 If you are between 18 and 40 years, you have normal hearing and you speak English well, you are eligible to participate in a 90-minute study. You will be asked to do five simple listening and learning tasks on the computer in the lab and a 15-minute recall task the next day that can be completed at home. For your work, you will receive a $25 gift card. Enrollment for this study begins January 2024 and will continue through May 2024.

If you have any questions or would like to enroll, contact the lab manager Nadiah Khalil at nabdulkhalil [at] mghihp.edu or 617-276-1140.

If your child has normal hearing or if they have hearing loss that can be improved with hearing aids, they may be eligible to participate.  Children will be asked to do five simple listening and learning tasks on the computer. Testing requires one visit of no more than two hours plus a 15-minute recall task the next day that can be completed at home. In return, they will receive $50 ($25 per hour). Enrollment for this study begins March 2024 and will continue through February 2025.
