The E-A-RTone 3A Insert Earphone is an audiometric transducer designed to be connected to an audiometer for the purpose of testing hearing. The device provides significant clinical and practical advantages over the supra-aural style earphone.
By directly coupling to the test subject's ear canal, via disposable foam E-A-RLink eartips, the E-A-RTone 3A Insert Earphone for audiometric testing provides both performance and reliability advantages over traditional supra-aural earphones.
Benefits (in comparison to supra-aural/TDH-style earphones) include:
Improved ambient noise attenuation
Greater interaural attenuation
Facilitated infection control (via disposable eartips)
Elimination of collapsed canal artifact
Better Test/Retest Reliability
Reduced Occlusion Effect for BC testing.
