How many personal noise dosimetries do I need to carry out?

The number of personal dosimetries to be conducted depends on the number of workers in the Similar Exposure Group (SEG).

An SEG is a group of workers who:

  • Perform the same job tasks.
  • Have similar job functions.
  • Work in the same area.

The SEG matrix can be found in the WSH guidelines on Hearing Conservation Programme.
