From a pickle-ball website:
Pickleball sound levels within 100 feet of courts will usually be around 70 dBa with no sound reduction efforts applied. This is as loud as freeway traffic sound.
70dBa is much louder than tennis, and the game should be played on courts that are designed to deal with the sound.
The pickle-ball people in the article mention that one of the reasons that they want to use this court, is "our homes are right here.” So it depends on how close those homes are, and what's between the courts and the houses.
