Mix and match modules

Affinity 2.0 is an agile piece of equipment. It combines a hearing aid test box with any module you need for your hearing aid fitting appointments. Adjust the package of modules to fit your needs.
Real-ear measurement software screen.


Real-ear Measurement
  • Objectively verify hearing aids by measuring the output at your client's eardrum.
  • Binaural REM - halve the fitting time.
  • On-Top mode - effectivizes the fitting process with a simultaneous view of the hearing aid fitting and REM software.
  • Simulation of life-like noise environments.
  • Combine REM with visible speech mapping to help your client acclimatize to her new hearing aids.

Hearing Instrument Testing
  • Endless loop testing.
  • Testing directional microphones.
  • Built-in test sequences.
  • Historical sessions.
  • Tests all types of hearing aids.
  • Variable smoothing of curves.
  • Telecoil testing.
Visible speech mapping software screen.


Visible Speech Mapping

Combines counseling with real-ear measures. This helps to visually explain what your client can hear.

The module also shows how your client's hearing aids accommodate her hearing loss.

A proven method to manage expectations and reduce the amount of follow-up visits.

„The B-81 bone vibrator provides higher output and lower harmonic distortion compared to the B71. This may offer a significant clinical advantage. Conductive components of severe hearing losses that cannot be measured with the B71 vibrator may be measurable with the B-81. This is important for medical diagnosis and treatment, programming hearing aids, and determining cochlear implant candidacy.“

Professor Emeritus, University of Minnesota Robert H. Margolis
