General information

Triangle is a portable screening audiometer capable of performing air conduction tonal audiometry manually and automatically, with a frequency range from 125 Hz to 8kHz.

The color touch display makes Triangle intuitive and easy to use, thus optimizing daily clinical practice management.

Automatic tests
Automatic tonal audiometry can be performed by choosing from three different protocols: 

  • Hughson-Westlake
  • Quick Search
  • Fixed Intensity

In addition to the Hughson-Westlake technique for determining the AC threshold, the user can select the Quick Search for threshold identification, which is based on the first response starting from the selected minimum level, or opt for the Fixed Intensity method, a basic screening test conducted at a fixed intensity level.

Portable system
Lightweight and compact, Triangle is extremely manageable and easily portable, thanks also to the provided soft case. Additionally, the rechargeable lithium-ion internal battery ensures more than 12 hours of continuous use, making Triangle the perfect choice for professionals on the go and for those requiring a reliable, simple, and fast screening solution. 

Triangle is also equipped with internal memory that allows storage of exams for up to 100 patients. It will then be very simple to transfer all the data from the audiometer to the computer simply by connecting Triangle to the PC via USB cable (optional 'PC Connectivity' license to be activated upon request).
