Calibrating Interacoustics audiometers and tympanometers

The ACS has built-in setups for 23 Interacoustics instruments, and 16 of them run under full automatic control. Select the model, start the calibration, and the ACS sets each test point, measures it and adjusts the instrument to ANSI S3.6 and IEC 60645.

Supported Interacoustics models

Every Interacoustics model the ACS calibrates

Automatic control means the ACS talks to the instrument through its serial or USB port: it sets frequency, level and channel itself and adjusts the instrument to the standard, and you only step in to change transducers. Models in manual mode are calibrated with the ACS prompting the technician for each setting and measuring the result.

How it works

A Interacoustics calibration, start to finish

  1. Select the Interacoustics model

    The ACS loads the right calibration routine and sets the headphone type and impedance for that model.

  2. Connect and start

    Connect the instrument’s outputs to the ACS interface, and on automatic-control models its serial or USB port. The ACS steps through every test point, recording the values it found before any adjustment.

  3. Print the certificate

    Every result, the Interacoustics and transducer serial numbers and the standard used, with your company logo. What a certificate should include.

Questions

Interacoustics calibration questions

Does the ACS adjust a AC40 by itself?

Yes. Under automatic control the ACS sets each test point on the AC40 and adjusts its output to the selected standard. The technician is only prompted to change transducers.

Can the ACS calibrate Interacoustics tympanometers too?

Yes. The AT235 and AT235h, AA220 and AA222, AZ7 and AZ26, and the Titan are supported, with probe tone level, compliance, pressure and reflex tests to ANSI S3.39.

How often should a Interacoustics audiometer be calibrated?

Under OSHA hearing conservation rules, an acoustic calibration at least yearly and an exhaustive calibration at least every two years. Calibration schedules.

Other calibration guides: GSI (14 models) · MAICO (20 models) · all 22 manufacturers.
