[Mobile soundproof booth for audiometric industrial testing]

Area of Science:

• Occupational health
• Acoustics
• Audiology

Context:

• Industrial workplaces present significant noise pollution challenges.
• Accurate audiometric testing is crucial for monitoring worker hearing health.
• Existing testing facilities may not be suitable for field deployment in industrial settings.

Purpose:

• To develop a mobile, sound-insulated unit for audiometric testing.
• To improve the feasibility of conducting hearing threshold tests in noisy industrial environments.
• To establish a controlled acoustic environment for occupational hearing assessments.

Summary:

• A caravan was modified with double-glazed windows, sealed doors, and sound-absorbing materials to enhance sound insulation.
• The modified caravan achieves significant noise reduction, enabling audiometric testing.
• Specific octave-band noise level limits were defined for effective testing within the caravan.

Impact:

• Facilitates on-site hearing screening and monitoring for industrial workers.
• Provides a practical solution for audiological assessments in challenging acoustic conditions.
• Contributes to better occupational hearing conservation programs.
