Dayton Blower Sound Level

Here are a couple of sound-measurements, for context. I used the NIOSH iOS app, with A-weighting, at a distance of 1.0 meters:

  • 30S-1 with Dayton 3,000rpm motor change: 59 dB(A) 1m directly in front
  • Listening to HF Radio, SSB voice: 65 dB(A) for my preferred Sound Level
