  • *The NRR may overestimate the hearing protection provided during typical use.

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.

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
