The E-A-RTONE™ 5A Insert Earphone is an audiometric transducer designed to be connected to an audiometer for the purpose of testing human 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™ 5A 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/Re-test Reliability
Reduced Occlusion Effect for BC testing
The E A RTONE™ 5A model does not require front tube replacement, and it has an extended high frequency range that will allow testing up to 12KHz.
