Triangle Screening Audiometer

The Triangle audiometer is a portable and lightweight device, designed to perform quick and accurate audiometric exams anywhere. This audiometer offers pure tone audiometry tests in air conduction, both manual and automatic, and optionally, with a license, also in bone conduction.

Triangle represents the pinnacle of technology in hearing screening devices, standing out for its unique features:
- Capacitive touch screen: It is the only one with this technology, offering an intuitive and accurate experience.
- Rechargeable lithium battery: Provides unparalleled autonomy and portability, ideal for professionals on the move.
- Bone conduction with masking: Allows for more precise bone conduction hearing evaluation (only available if bone conduction option is purchased)
- Italian design: Elegant and functional, reflecting Italian excellence in engineering and design.

Triangle adapts to the needs of each professional, offering manual and automatic pure tone audiometry in air conduction (test range from 125 Hz to 8 kHz). In addition, it allows you to expand its functionalities through optional licenses (at an additional cost):
- Bone conduction license: Adds bone conduction audiometry and masking signals.
- Computer connectivity license: Allows test results to be transferred to Maestro or Noah databases.

In addition, Triangle offers three automatic pure tone audiometry protocols to adapt to different needs:
- Hughson-Westlake: Determines the air conduction threshold accurately.
- Quick Search: Identifies the threshold quickly and efficiently, based on the patient's first response.
- Fixed Intensity: Basic screening test performed at a predefined intensity level.
