Field-Deployable Intensimetric Probe System for Early Diagnosis and Monitoring of Noised-Induced Hearing Loss and Traumatic Middle Ear Injury

Abstract

The goal of this project is to develop field-deployable technology for the early diagnosis and monitoring of NIHL and traumatic middle-ear injury in Service Members and Veterans, enabling both the more accurate evaluation and the application of preventative therapies and treatments for hearing injuries. Our main objective is to develop and validate a highly innovative intensimetric probe system that has a microphone for sensing acoustic pressure, and a velocimeter for sensing acoustic velocity, allowing for the direct measurement of acoustic impedance, without the need for Thevenin calibration. This will allow for the reliable assessment of middle and inner-ear auditory function ear function without the need for complex daily Thevenin calibration in a package that is suitable for field use.
