[NSRCA-discussion] Sound measurement

[Jon Lowe]

Does anyone know where the requirements for the settings on the dB meter are in the Competition regulations?  The regs are very specific as to the placement of the sound meter to the aircraft, distances, etc, but I can't find the requirements for the use of "A" or "C" weighting, or "Fast" or Slow" response.  I think we are supposed to use "A" weighting, and Slow response, but I'm not sure.
