The AD629 offers a familiar interface with all the features of a traditional standalone audiometer. In addition it offers features typically found only with PC-based platforms such as EMR integration, flexible reporting tools and database storage (NOAH, OtoAccess™).


  • Full PC-integration (true hybrid)
  • High performance and speed
  • Versatility
  • Extensive diagnostic test battery


  • Large 5,7″ adjustable high resolutiongraphical color display
  • Internal storage for 500 patients / 50,000 test sessions
  • Integrated pre-recorded speech
  • Direct print options
  • Compact and portable design (35 x 29 cm / 14 x 11 inch.)

Design perfection

The design and ergonomics of AD629 is truly exceptional. The large 5.7 inch/14.5 cm high resolution color display presents a clear image with easy to read audiograms. No need for pen and paper! The articulating display is easily adjusted to your preferred reading position.

Familiarity and speed

The familiar and intuitive button layout allows to keep an eye on the patient during testing. It is ergonomically designed for optimal speed and comfort. Several viewing modes make it possible to configure it for your optimal use by choosing between single or dual audiogram mode and graph or table speech displays.

Ultimate versatility

The AD629 presents a professional image whether in a clinic – or on the  road. The internal processor makes it possible to bring it on the road without needing to bring a computer for storage. Connect to the PC back in the office and synchronize with the local EMR (Electronic Medical Record) system or database (e.g. NOAH or the Interacoustics database OtoAccess™).
