R37A Clinical Audiometer

Compact dimensions, excellent ergonomics and a luminous 7” TFT display: R37A Resonance® Audiometer has been engineered to respond to the needs of ENT and Audiology Specialists, operating both in clinic and medical practice. Design is user-friendly and allows both device and accessories to be safely carried around in a practical carrying case, available on demand.

High-quality components ensure device reliability as well as long-term operation. Recognized dependability matches with efficiency. Test-report files, generated in PDF, can be initially stored on a USB-stick, then archived into external units or printed, thanks to the built-in thermal printer. Reports can be easily edited and customized with additional text and logos.

The R37A offers a complete range of clinical tests including air and bone conduction tests, SAL and speech audiometry, up to 20KHz High Frequency Test in R37A-HF confi guration. Speech material in English and Spanish is recorded on the Resonance SD-Card. Confi gurable tests and preferences designed to improve daily workfl ow and optimize speed and reliability of testing.
