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.

Connectivity & Software Integration

• Bidirectional PC interface for remote control and data management.
• Compatible with clinical software such as:
  • OtoAccess™
  • NOAH
  • PrintView
• Enables centralised patient record storage and printing.

Communication & Monitoring

• Integrated gooseneck microphone (talk-back).
• Internal speaker monitoring plus headphone monitoring available.
• Inputs for external microphone and playback devices (CD/cassette).

Transducer Support

Compatible with a wide range of transducers including:

• TDH-39 headphones
• Bone vibrator B71
• EAR-Tone 5A insert phones
• CIR22 insert sets
• Free-field systems with external amplifiers/speakers

Technical & Practical Specs

• Type: Two independent audiometry channels (clinical grade).
• Frequency range & intensity: Standard clinical audiometry range up to 8 kHz for AC/BC/Free Field depending on transducers.
• Power: 100-120 V or 200-240 V (50/60 Hz).
• Weight: ~9 kg (portable bench device).

Usage and Workflow

• Intuitive interface with easy-read display and manual controls.
• Offers flexibility in selecting test stimuli and transducer configurations, making it suitable for routine clinical hearing exams.
