Workshop Safety

Hearing Protection

A router runs at about 95 dB. Damage is permanent and cumulative, which is why earmuffs live next to the machine.

What it is for

A router runs at about 95 dB. Damage is permanent and cumulative, which is why earmuffs live next to the machine. This guide covers what the tool does, the specification points that actually change your results, and how to use it without damaging the work or yourself.

Where it fits in the build

This is a maintain stage tool in the Workshop Safety category. Protect eyes, ears and lungs on every job.

Maintain Workshop Safety

Using it well

  • Earmuffs give roughly 25 dB of attenuation; foam plugs give about 30 dB when fitted well.
  • Combine muffs over plugs for the loudest operations such as routing and thickness planing.
  • Replace the cushions when they harden or crack — a poor seal loses 10 dB or more.

Compatible materials

Materials this tool handles without compromise. Where a material is not listed, check that the tool is rated for it before committing to a cut.

  • No material dependency
Educational content only. Settings, capacities and safety guidance here are general starting points, not instructions for your specific tool, material or situation. Always follow your tool manufacturer's manual and any material datasheet, and check your own measurements before cutting.
