The Revolution in CI-assessment

Nominated for the 2013 Rabobank Innovation Award for Health Care


Otocube is a revolution in testing CI-patients. It is a high-tech and portable desktop box which replaces a fully equipped audiological room. It outperforms a clinical booth in acoustical insulation and contains all electronics,  high-end amplifier and loudspeaker to deliver well calibrated sound between 10 and 120 dB HL to the CI processor in the box. Close the box and take a long headpiece cable to transfer the sound from the processor to the patient’s ear. The box easily connects “plug and play” to your laptop or PC. Thanks to our custom-made audiological software A§E, you readily perform audiometry, speech audiometry in any language, loudness scaling, spectral discrimination, temporal fine structure tests, etc.

Field Trials


We polled the market in CI-centers in Belgium, France and the Netherlands. Ten centers* received an otocube prototype for beta-testing. They rated its features by means of appreciation stars.


  • calibrated and swift audiometry with A§E Diamond
  • a worthy alternative for overoccupied soundproof booths


  • mobile testing possible
  • realtime monitoring of the sounds presented in the spectral and temporal domain


  • very fast and calibrated speech audiometry with A§E Diamond
  • brilliant idea to use a long headpiece cable to connect the CI recipient
  • great look & feel, dimensions & weight
  • indispensible to distinguish electric hearing from acoustic hearing in EAS
  • portable and far less expensive than a fully equipped audio booth
