AuD Capstone Projects - Communication Sciences and Disorders

The anthropometrics of the external auditory canal (EAC) is clinically pertinent to producing effective custom hearing protection devices (HPD). If custom HPDs are incorrectly fit, they will not attenuate an appropriate level of sound, increasing the likelihood that the user might be exposed to hazardous intensity levels. Researchers have attempted to measure the EAC using a multitude of approaches. Research technology, called ear scanning, appears to provide the ability to measure the EAC effectively. This study was designed to identify a procedure to accomplish the following: (1) characterize the anthropometric differences between male and female external ears. (2) identify differences …
