Details
  • 3M PSD products are for occupational use only.
  • *The NRR may overestimate the hearing protection provided during typical use.

The E-A-RLINK™ 3B is a 1/2 inch height Small/ Pediatric size (9.7mm) diameter beige foam disposable/ single-use ear tip with a black tube for use with the E-A-RTONE™ 3A and 5A Insert Earphone.

 

By directly coupling to the test subject's ear canal, via disposable foam E-A-RLINK eartips, the E-A-RTONE 3A and 5A Insert Earphone 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

Infant Eartips are designed to be used as an alternative for the foam (E A RLINK ) eartips connected to the E A RTONE Insert Earphone in instances where the smallest (3B) foam tip size is too large for the test subject's ear canal.
