"It has been shown that averaging techniques such as equivalent-continuous and maximum fast exponential time weighted sound pressure levels (LAeq and LAmax) are not well suited for assessment of short duration impulsive sound like that produced by the impact of a pickleball on a paddle. 

These metrics can be expected to substantially underestimate the community response to this type of sound.

 Measurement procedures based on the adjusted sound exposure level according to ANSI S12.9 Part 4 have been described as a more accurate methodology for noise impact assessment of pickleball."

"It can be expected that the sound levels at nearby property lines will exceed the limits set by the Davidson, NC ordinance of 65 dBA by as much as 7 decibels if no steps are taken to reduce the sound levels. 

River Run will need to mitigate this level with heavy-duty sound barriers or requiring the use of quieter gear along with the use of modest sound barrier materials and thick vegetation along the north and along part of the east fencing of the new courts. If these steps are taken, we predict that there will be no violation of the local sound ordinance."
