Subject: Spot Sampling for OMC1 Training Room

Hello Ron,

Thanks for reaching out to us regarding the noise at the training room produced by the 2 servers
behind the workstation.

At the time of spot sampling today, at around 07:40-45 we got values between 56 - 63 dBA
(depending how close we got to the server rack)
© This value was below the occupational exposure limit of 85 dBA —- TWA (8-hours), although we

did not measure for 8 hours, we are assuming the noise does not fluctuate much.

Some suggestions to consider:
1.
2.
