3. Acoustical Measurements Description and Results
3.1 Test Description
3.1.1 Purpose Acoustical measurements were made at four locations on three sides of the pickleball courts. These measurements have been used to compare the noise impact produced by different makes of pickleball on the surrounding RV slots as well as the directivity of the pickleball courts. 3.1.2 Measurements and Equipment A-weighted acoustical data was logged with a NTi XL2 type I integrating sound level meter. Simultaneous, calibrated digital recordings were also made by the meter to document and identify sound sources. These recordings were also used for more detailed analysis of the impulsive sound of the pickleball and paddle impact. The microphone height was 52 inches unless otherwise noted. A three inch diameter wind screen was placed over the microphone. Meteorological observations were made during the time of the acoustical measurements using a Kestrel 4500 weather station. Temperature, humidity, wind, and pressure data were logged every 20 seconds. This data is displayed in the appendix. The engineer on site was Lance Willis. 3.1.3 Pickleball Courts The surface of the pickleball courts was painted asphalt. The courts were surrounded by a chain link fence approximately eight feet in height with wind break cloth. The courts were slightly higher than the road surface on the west, south, and east sides. There are 13 pickleball courts with six on the west half of the site and seven on the east. Four players were on each court. During testing only the courts on one side were active at a time, either the east or west side. This was done to better quantify the directional characteristics of the courts. Measurement results in this chapter reflect those conditions. The total sound pressure levels will be presented in a later chapter along with the full site model.
