Description

The booth is developed for hearing testing in medical and research centers, production sites, schools and institutes. It provides a controlled acoustic environment for medical examinations. This ensures accurate hearing testing results during mass screening.

Capabilities and Advantages
  • High Sound Insulation: Provides excellent soundproofing, airtightness and noise absorption to create optimal conditions for conducting speech and tonal audiometry using headphones.
  • Noise Absorption: The cabin absorbs both mechanical and acoustic noise effectively. The door is equipped with a double magnetic seal around its perimeter.
  • Two-Way Communication: A built-in intercom system enables communication in both directions.
  • Forced Ventilation: The cabin is equipped with forced ventilation with noise suppression.
  • Integrated Air Disinfection: A built-in closed-type irradiation recirculator disinfects the air by means of a bactericidal lamp.
