Description
- Disposable, single-use foam eartip with black tube for use with E-A-RTONE 3A and 5A Insert Earphones
- 3B Beige are Small, Pediatric Size - 1/2 inch height, 9.7mm diameter
- Latex-free
Made from the same foam material as 3M Classic Yellow or Beige earplugs which have been on the market for over 30 years and extensive toxicological testing has been performed to support the conclusion that they are safe
By directly coupling to the test subject's ear canal, via E-A-RLink eartips, E-A-RTONE insert earphones for audiometric testing provide 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
