E-A-RTONE® Insert Earphones

The E-A-RTONE® 3A Insert Earphone is designed to be used with any audiometer in pure tone or speech audiometric testing. It is available in three impedance versions (10), 50 and 300) to accomodate most screening or clinical equipment. Calibration procedures are presented in the current ANSI Standard "Specification for Audiometers" (S3.6-1996) and the International Standard (ISO 389-2) "Acoustics - Reference zero for the calibration of audiometric equipment", Part 2. The unique E-A-RLINK® foam coupling system provides fundamental clinical and practical advantages over a supra-aural earphone that can save time and enhance test reliability.

E-A-RLINK™ EARTIPS
E-A-RLINK™ eartips which are composed of a polyvinyl chloride material and contain no latex, are available in three sizes:

 

 

  • E-A-RLINK™ 3A - 13.7mm(0.54") diamater for most ear canals.
  • E-A-RLINK™ 3B - 9.7mm(0.38") diameter for small ear canals.
  • E-A-RLINK™ 3C - 17.8mm(0.70") diameter for extremely large ear canals.

Samples of all three sizes are included with each E-A-RTONE® insert earphone. It is recommended that E-A-RLINK™ 3A eartips be tried on each adult patient first. If the E-A-RLINK™ 3A is too large, refit with an E-A-RLINK™ 3B. If the E-A-RLINK™ 3A tip is too small, it is recommended that E-A-RLINK™ 3C tips be used.
