Oakmont Village, a Santa Rosa, CA community, commissioned a Pickleball sound study in 2017. In order to determine if the noise was within town code, they needed to assess decibel levels on 6 tennis courts with and without Pickleball play. The decibel levels ranged between 43 and 49 dB when 24 active Pickleball players were whacking away.

In the present work, vibration, acoustic and thermal signals were correlated to the semiautogenous grinding mill working parameters such as total power and inlet water flow rate, and then these parameters were monitored using vibration, acoustic and thermal analyses. Next, the influential controlling parameters were obtained to monitor the mill conditions via SPSS software and afterward by ...

The major negative impact associated with pickleball is noise. When the hard surface of the pickleball racket connects with the hard surface of the ball, sound waves vibrate rapidly, registering a decibel level of around 70 dBA at 100 feet from the court. (In comparison, tennis noise is closer to 40 dBA.) This article by Mark Dent features Bob ...

"The noise from your project exceeds the local noise ordinance." This is generally the most straightforward issue to address. If a neighbor believes the noise from a construction site exceeds what is permissible by law, as little as a few days of construction noise monitoring and subsequent analysis could be enough to determine whether the site is in compliance.
