The E-A-RTONE 3A ABR Insert Earphone is an audiometric transducer designed to be connected to auditory evoked potential equipment for the purpose of objectively evaluating human hearing.
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
