Table 3.2 shows a summary of the entire measurement for each ball at Point 1. This data contains frequent events not related to pickleball and is similar to the background noise measurement.

Table 3.2. Sound Pressure Level Data Summary at Point 1
Table 3.3 shows the A-weighted equivalent-continuous sound pressure level for only pickleball. These levels do not include any adjustment for the impulsive nature of the paddle and ball impacts. This will be covered in the next chapters. The sound pressure levels show a little variation with ball type and are mainly a result of speech on the pickleball courts.
