VerifitLINK

Automated fit-to-target

Automatic

  • Audiogram transferred from Noah to the equipment automatically.
  • Fitting software mutes hearing aids during sound field equalization without clinician intervention.
  • Near-instantaneous gain adjustment to NAL-NL2 or DSL 5 targets.1

Accurate

  • Closer target match than manufacturers’ quick fits for soft, average, and loud speech.1,2
  • Equivalent target match to experienced clinicians using manual adjustment procedures.1
  • Excellent test-retest reliability.1, 2

Objective

  • Uses NAL-NL2/DSLv5 targets of the verification equipment, not those of the fitting software.3
  • Results match those obtained through manual Speechmap verification.
  • Digital signal processing and analysis is performed by the Verifit, not the fitting software.3

Quick

  • Save valuable time, allowing you to see more patients, counsel, etc.
  • With simultaneous binaural implementation, fitting hearing aids to targets at multiple input levels can be done in ~2 minutes instead of close to 10 minutes without VerifitLINK.4

VerifitLINK is not IMC2.

HIMSA’s IMC2 protocol allows REM modules in Noah to be controlled by hearing instrument fitting modules, also running in Noah. Through this, the REM hardware is made available to the fitting software which then becomes both the fitting software and the verification system.

VerifitLINK is different in that it allows for a direct connection between the fitting software and the Verifit system. VerifitLINK does not depend on Noah and does not allow the fitting software free reign over the REM hardware.

The benefits are a more consistent, objective implementation and absolute equivalency between manual and automated measurements.1

Clinicians who trust their Verifit can trust the results of VerifitLINK in their fitting software.

*VerifitLINK is available on all Verifit2 devices and Verifit1 serial number 2070 and higher.
