Hearing instrument test box

The hearing instrument test box (HIT) features a large test chamber to provide excellent acoustics for hearing aid tests and hearing aid configuration before your customer arrives.

Outstanding elegance and precise measurements

Accurately pre-set and test hearing aids with the large hearing instrument test box. Its stylish design makes it a professional eye-catcher for your office environment.

Available standard tests:

  • IEC 60118-7
  • IEC 60118-15 (in combination with the speech mapping module)
  • ANSI S3.22

Measurement screen

The HIT measurement screen demonstrates what is happening inside the test box during test sessions. It provides clearly structured test orders, automatic test runs and readout of data.

Other tests:

  • OSPL 90
  • Battery current
  • Full on gain
  • Induction coil test
  • Frequency response
  • Input / output
  • Harmonic distortion
  • AGC dynamic
  • Equivalent input noise
  • Long term test (monitor output signal and batt. consumption over several hours), from SW version 6.1 onwards
  • Free style test with broadband signal
