FEATURES:

Core Functionality

Two-channel clinical audiometry

• Supports air conduction and bone conduction testing for accurate threshold measurement.

• Designed as a clinical-grade audiometer for diagnostic use.

Extensive test battery

• Automatic threshold testing using the Hughson-Westlake method (Auto Threshold).

• Standard audiometric tests including:

  • ABLB (Alternate Binaural Loudness Balance)

  • Stenger test (pure tone or speech)

  • Speech audiometry (voice tests with automatic scoring)

  • SISI tests with automatic scoring

• Supports tone in noise and other clinical protocols.

Masking & Tone Presentation

• Automatic masking that selects appropriate noise levels (narrow band, broadband etc.).

• Synchronised masking to ensure correct ear isolation during testing.

• Tone stimuli include continuous, pulsed, warble ( 5 %, 5 Hz), single/multiple pulses.
