Notes:

  1. All readings are 'A-weighted' levels - i.e. average noise levels - and were taken at normal working height.
  2. Stipulating noise levels which require the mandatory use of personal protective equipment (PPE) involves both the power of the noise, and the length of exposure to that noise. For noise at 85 dB, continual exposure of over 8 hours would require PPE.
  3. Actual noise levels in this room could increase markedly were many GPU servers in active use.
  4. The next noise survey for this room will be done in January 2022 (or sooner, if the equipment in use in the room changes markedly.)
