Hearing Test System

Unlike tone response tests, the new E-A-Rfit™ Validation System from E® is an F-MIRE (field-microphone-in-real-ear) test system that incorporates a dual-element microphone to measure sound inside and outside the ear. In seconds, a personal attenuation rating (PAR) can be obtained in seven standard frequencies (125Hz to 8000Hz).
