Our Anechoic Chamber

Researchers with our R&D program promote advancements in hearing and speech science to enhance the quality of life for children and adults with hearing loss. Our anechoic chamber (pictured below) provides an excellent laboratory setting for conducting research.


Significant progress has been made to standardize the Tonality Word List. In the near future, our research team will be seeking grants from federal agencies such as the National Science Foundation, National Institutes of Health and National Institute on Disability and Rehabilitation Research.

Our research program would not be possible without the generous support of Alan and Lisa Boeckmann, Judy Boeckmann, the Fluor Foundation and Blount Hearing and Speech Services.
