Audibility, Perception and Cognition Laboratory

What We Study

​Dr. Ryan McCreery, PhD, is the director of the Audibility, Perception, and Cognition laboratory. Our research aims to describe how amplification, language and cognition support speech perception in children who are hard of hearing in effort to maximize outcomes for children wearing hearing aids. The goal of our research is to better understand how hearing loss impacts the ability of children to listen in classrooms, at home and in social environments where important communication takes place.


Hearing aids worn by children are often designed for adults, without consideration for a child’s developing auditory skills. The ability to temporarily store and process incoming auditory information, known as working memory, and knowledge about language can help to support listening in environments where the speech signal is degraded by noise and reverberation. Dr. McCreery explains more about the research being done in the Audibility, Perception, and Cognition laboratory in the video below.​

Facilities

Our lab facilities include multiple double-walled, sound-treated audiometric test booths. These booths are equipped with audiometers, immittance equipment and hearing aid verification systems. Listening environments are simulated through multiple speaker arrays controlled via MATLAB and Max custom software programs.

Our Studies

FASTRAK Study
Our goal is to help audiologists determine when a child may benefit from hearing aids. To do that, we plan to develop clinical tools that can tell us when a child is experiencing difficulty and could benefit from a hearing aid.
Complex Listening Study
​​Some children who are har​d of hearing have trouble understanding in background noise, eve​n when hearing aids provide good audibility of speech. We are trying to understand how other factors, like a child’s ability to tell differences between sounds or how a child remembers and pays attention, affects their speech understanding in noisy places..
Speech Attention and Understanding in Noise Study
Some children who are har​d of hearing have trouble understanding in background noise, eve​n when hearing aids provide good audibility of speech.
Children's Skills Supporting Listening in Noise Study
The purpose of this study is to identify and understand what type of intervention can help children better understand in noisy environments, such as classrooms. Participants will be asked to repeat words and sentences in quiet and noisy situations and play memory and attention games. Hearing tests will be given to those who have not had one in the past six months.
