Notes on sound level data
  • This data is for informational purposes only and is of indicative value only. It was collected using a non-calibrated device under uncontrolled circumstances.
  • The data unit is "dBFS" (Decibels-Full Scale). 0 dBFS is the loudest sound the device can capture. Lower values, like -99 dBFS, mean very low noise. Higher values, like -10 dBFS, are very loud.
  • The system measures the RMS of the sound level for contiguous periods of 5 seconds.
  • 'Loudness' is the difference (in dB) between the Peak RMS Sound and the 1 hour average. It provides an indication of how much louder than normal it was when the aircraft flew over.
  • Loudness values of greater than 16 dB are in red. Values greater than 9 dB are in yellow.
  • 'Peak RMS Sound' is the highest measured 5-seconds RMS value during the time the aircraft was in the coverage area.
  • The subsequent values are 1, 5, 10, and 60 minutes averages of these 5 second RMS measurements for the period leading up to the moment the aircraft left the coverage area.
  • One last, but important note: The reported sound levels are general outdoor ambient noise in a suburban environment. The system doesn't just capture airplane noise, but also trucks on a nearby highway, lawnmowers, children playing, people working on their projects, air conditioner noise, etc.

Heatmap
  • This heatmap reflects passing frequency and does not indicate perceived noise levels
  • The heatmap is limited to the coverage area of Planefence, for any aircraft listed in the table above
