The explosive growth of the game — played on a small court with a paddle and a plastic ball — saw participation nearly double in 2022, increasing by 85.7% year-over-year, and by 158.6% over three years, according to the Sports & Fitness Industry Association.
"Over the last several months, I just kept seeing them kind of pop up. And all these lawsuits, of course, were largely over pickleball being too noisy," he told NPR.

Fancy a game?
What are people saying?
Here's Dent telling NPR why he started looking into this:
Pickleball is, like, the worst of both worlds. You know, it's loud, and it's high-pitched ... So I'm like, how can pickleball be less noisy? Is anybody working on it?
It turns out, Unetich was. Here's what he told NPR he has found out:
Pickleball sound exists right in that most sensitive range. An interesting thing I learned along the way is that garbage truck backup beepers are right in the same pitch of pickleball. Why did they pick that sound for beepers? Because it's the most annoying frequency.
And how Unetich and a couple of other engineers tested different paddles for sound levels:
We built a tall chamber. We found dropping a ball — if there was no wind, no air — enabled you to get a very predictable speed. And so a ball hitting one paddle will give you a different sound than a ball hitting a different paddle.

Pickleball became a pandemic-era darling, because it could be played in relative safety outside.
So, what now?
Unetich's research has found that different materials in the equipment, as well as sound barriers, can help. Still, the simplest solution is just to build courts far enough away from people.
"It's kind of like having to invest more money on the front end and planning to avoid this potential major disruption and lawsuits — conceivably at least — on the back end," Dent said.
Unetich worries the noise problem will slow the growth of his favorite sport. He's hoping his research and consultancy will help so he can keep playing.
The U.S. Centers for Disease Control is reporting seven more illnesses have been reported linked to prepared pasta meals that may be contaminated with Listeria monocytogenes. CDC and states are working to get information on whether sick people ate recalled food or if additional foods may be contaminated. Twenty-seven people have been affected across 18 states, including Florida, with 25 hospitalized, and there have been six deaths.
Sea turtles had a much better nesting season this year on Keewaydin Island than in 2024. The Conservancy of Southwest Florida’s sea turtle research team counted 558 nests all loggerhead nests except three from green turtles. This year, more than 38,000 hatchlings made it.
Florida is the land of sunshine and good vibes, but when the sun goes down on Downtown Fort Myers, something ghastly takes over. The waterside community is home to spiritual abnormalities that have caused spine-tingling reactions for decades.WGCU’s Samuel Brucker took part in a Historic Downtown Tour to learn the horrific stories that have turned into urban legend and have given a taste of the macabre to Southwest Florida.
