Grinn, Sarah

Associate Professor

FACULTY

Biography

Dr. Grinn is a tenured Associate Professor in the Doctor of Audiology program at Central Michigan University. She leads clinically translatable research focused on understanding individual susceptibility to peripheral and central noise-induced hearing injury. The purpose of Dr. Grinn’s ongoing NIH NIDCD R01 project is to improve the safety and audibility of automatically programmed hearing aids such that they do not overamplify or underamplify when programmed using average estimates of external-ear resonance. Concurrently, the purpose of her ongoing NIH NIDCD Clinical Research LRP Award is to investigate the effects of external ear mechanics on temporary auditory deficits following recreational noise exposure.
