Affinity Compact

Affinity Compact


The complete hearing aid fitting solution with a noise-cancelling lid (modules still optional) for hearing instrument testing.

Made for your clinic

Affinity Compact has an elegant design, which gives you the ability to mount the unit as you wish and to wipe down its surfaces.

The unit powers down when not in use and it has a light indicator. The light indicator turns blue when testing the left ear and it turns red when testing the right ear. The light indicator also has specific colors for each module.

Made for your client

Engage your clients and their support.
The Affinity Suite offers a variety of tools that include the client and support in his or her hearing rehabilitation. This results in better counseling, which will reduce the amount of follow-up visits.


The AC440 module offers simple hearing testing.

Flexible test battery

You can tailor the test battery to your needs by only buying the licenses you wish.

Audiometry up to 20 kHz

You can test with sound frequencies up to 20 kHz. This is useful for:

  • Early intervention
  • Ototoxic monitoring
  • Tinnitus matching
  • Hearing aid fitting

Ambient Noise

Ambient Noise measures the sound environment in relation to hearing thresholds. This gives you more confidence in your audiograms – even in noisy environments.

Free field adjustment

This feature uses a microphone and stimuli to adjust the stimulation. This ensures an accurate free field stimulus.

Automated test with IA-AMTAS

The IA-AMTAS test feature is an automated method for obtaining a diagnostic hearing test. It allows patients to perform a hearing test on their own, which frees up time for the busy clinician. Once the patient has completed the IA-AMTAS test, you can access a summary report with the test data and quality indicators of the session.

Real-Ear Measurement

Real-ear measures enable perfect fitting in any ear canal.

Easy probe tube placement

Avoid any contact with your client’s eardrum and be certain of accurate real-ear measurements. Based on machine learning, Affinity Compact’s Probe Placement Indicator shows insertion depth in real time, and provides a visible and audible signal when you’ve inserted the probe tube at the correct depth.

Get fitting right

Real-ear measures are objective and show what a hearing aid is doing in your client’s ear.

Binaural REM

The binaural REM feature allows you to fit both ears at the same time. This halves the fitting time.

Hearing Aid Transition

This test allows you to copy hearing aid settings. This makes it simple to adjust new hearing aids.

Realistic stimuli

The use of life-like stimuli gives your clients the ability to hear how their hearing aids work.

12.5 kHz REM

REM up to 12.5 kHz enables you to provide a thorough hearing aid fitting for your client.

Hearing Instrument Testing

The HIT440 module can verify any hearing aid.

Eliminate background noise
The removable and cleanable sound-absorbing base and the sound-proof chamber provide reliable results.

With you for any evaluation
Using telecoil and directional microphones, HIT440 can evaluate any hearing device or bone-anchored hearing instrument. Choose from ANSI or IEC tests or create your own.

  • Listen to coupler – hear what your client hears
  • Historical results

Aidapter™: Moving beyond acoustic putty
The Aidapter™ is a unique silicone piece that clicks onto the HA-1 adapter. You can use the Aidapter™ with receiver-in-canal (RIC) and thin tube hearing aids. Compared to acoustic putty, the Aidapter™ provides a good acoustic seal and standardizes the coupling, ensuring repeatable coupler measurements.

Integration made easy

Get more time to take care of your client.
Affinity Compact is compatible with Noah and OtoAccess®. This means you can integrate with EMR and EHR systems. Spend less time on data handling and more on your client.
