Hearing Protection at Workplace
Occupational hearing loss is one of the most common occupational diseases worldwide. Every year, millions of workers experience permanent hearing loss due to sound levels they are exposed to in noisy work environments. In this guide, we discuss what you need to know and the precautions you should take for hearing protection at the workplace.
Occupational Noise Exposure
Workers in sectors such as construction, manufacturing, aviation, mining, and agriculture are exposed to noise above 85 dB daily. According to European Union regulations, employers must provide hearing protectors to workers exposed to noise above 80 dB daily. At 85 dB and above, use is mandatory. Similar regulations exist in Turkish occupational safety legislation.
Choosing the Right Hearing Protector
Foam Ear Plugs: With high NRR values (29-33 dB), they are ideal for heavy industry and construction environments. Used with the roll-and-insert technique, they expand within 15-20 seconds making the ear canal completely sealed.
Corded Foam Ear Plugs: The corded design that prevents loss provides practicality in workplaces. You can remove them during breaks and hang them around your neck, then put them on immediately when starting work.
Silicone Ear Plugs: Durable and reusable structure makes them economical for long-term use. Easy cleaning provides a hygiene advantage.
Creating a Hearing Protection Program
- Conduct noise measurement: Determine sound levels in the workplace with professional measurements.
- Perform risk assessment: Calculate exposure durations and risk levels.
- Select appropriate protectors: Determine hearing protectors suitable for noise levels and working conditions.
- Provide training: Educate workers on proper use, maintenance, and replacement schedules.
- Regular inspections: Regularly check the condition and usage of protectors.
- Conduct hearing tests: Provide early detection with annual hearing tests.
Legal Requirements
Under Turkey's Occupational Health and Safety Law No. 6331, it is the employer's responsibility to ensure workers use hearing protectors in noisy environments. According to the Noise Regulation, the daily exposure limit value cannot exceed 87 dB. When employers cannot control noise risk at the source, they are obliged to provide appropriate personal protective equipment.
