Triangle is a stand-alone, portable screening audiometer, capable of performing automatic and manual pure tone audiometry exams in air conduction as well as, optionally licensed, in bone conduction.

The color touchscreen display makes the Triangle intuitive to use, thereby optimizing the daily practice.

Thanks to its lightweight compact design and the rechargeable lithium battery included, Triangle is the ideal choice for professionals on the move, as well as for whom requires a reliable solution for hearing screening.


Triangle represents the state-of-the-art among the screeners:

  • The only one with a graphical display with capacitive touchscreen
  • The only one with a rechargeable lithium battery
  • The only one featuring bone conduction with masking
  • …and the only one with an astonishing Italian design!


The basic version of Triangle offers manual and automatic pure tone audiometry in air conduction, with a testing range from 125Hz to 8kHz.

You can upgrade at any time your Triangle with the following optional licenses:

  Bone Conduction license

     To conduct pure tone audiometry in bone conduction and to enable masking signals.

  “Computer-connectivity” license

     To transfer exam results to your Maestro or Noah database


The Automatic Pure Tone audiometry can be performed choosing among 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 minimum selected level, or opt for the Fixed intensity method, a basic screening test conducted at a fixed intensity level.


Lightweight and compact, Triangle is extremely handy and easily transportable even thanks to the dedicated soft carrying case included with the device.

Triangle can be battery operated: its Lithium-Ion internal rechargeable battery guarantees more than 12 hours of continuous use.

Triangle is also provided with internal memory to store the exams of up to 100 patients: it will be very easy to transfer all the data stored in the audiometer to the computer by simply connecting the Triangle with the PC using the USB cable (”Computer-Connectivity” license required).

Package includes: Air conduction transducer ( - choose it from above - ), Patient response switch, Medical grade power supply, USB connection cable, Audiogram cards, Carrying case, User Manual.
