  • 3M PSD products are for occupational use only.
  • *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

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.
