When Is Noise a Problem?

The regulations require employers to assess workplace noise, reduce exposure where possible, and provide suitable hearing protection when noise reaches certain thresholds. The first action level is around 80 dB, when employers must provide information and make protection available. At 85 dB, workers are required to wear hearing protection, and more formal noise control measures are needed.

Some typical workplace levels:

• Circular saw: 100–110 dB
• Angle grinder: 95–110 dB
• Tractor cab: 85–90 dB
• Pressure washer: around 95 dB

These figures show why hearing protection is essential even for people who only spend part of their day using loud tools.

How Work Noise Damages Hearing

Workplace hearing damage usually develops slowly over years. At first, people might only notice occasional ringing in the ears after a shift, or that they struggle to hear conversations in busy environments. Over time, continuous exposure at 85 dB and above can cause permanent loss, especially in the high frequencies that help with speech clarity.

Studies on industrial workers have shown that long-term exposure to loud noise can also be linked with fatigue, stress, and difficulty concentrating, further highlighting the importance of protection.

Choosing Protection for Work

For many jobs, over-ear ear defenders are the most practical choice. They are easy to see, quick to put on and remove, and provide a consistent seal around the ear. Bright, high-visibility designs – like yellow DIY-style defenders – also make it obvious to supervisors that protection is being worn.

In workplaces where noise levels vary, such as warehouses or workshops, defenders can be lifted off between tasks and put back on for noisy activities like cutting, grinding, or hammering. In contrast, earplugs may suit people who move constantly between loud and quiet areas, or who wear helmets and visors.

Some workers choose to keep a small set of reusable earplugs in their pocket as a backup. Sonic or filtered plugs can be useful when you need protection but still want to hear alarms, conversation, or traffic clearly.

Good Habits Make the Difference

Regulations and equipment only go so far; the real protection comes from consistently using what’s provided. Putting on ear defenders whenever you start a loud task, checking the condition of your gear, and replacing worn cushions or plugs regularly are small habits that protect your hearing for decades of working life.
