Here's a few points of reference:

  • Near total silence - 0 dB
  • A whisper - 15 dB
  • Normal conversation - 60 dB
  • A lawnmower - 90 dB
  • A car horn - 110 dB
  • A rock concert or a jet engine - 120 dB
  • A gunshot or firecracker - 140 dB
At what point of reference is the 105 dB limit? For example, 1 foot from the rear, 50 ft away, etc.
There's a check station on the uphill straight between turn 5 and 6, not exactly sure how close it is to the cars. Hopefully the distance helps.
