Pickleballs' loud 'pop' sound can reach 120 decibels, equivalent to the sound of a hammer striking a nail.

Pickleball's popularity has exploded in recent years

Pickleball has seen rapid growth in the US, with around 50 million Americans playing in 2022. It doesn't appear to be slowing any time soon.

Pickleball players and tennis players are running into problems over court space

Pickleball has become one of the fastest-growing sports in North America, especially for older adults. It's also led to tension with tennis players, whose courts are now being overtaken by pickleball players, with some municipalities adding pickleball lines to tennis courts.

PIckleball is the fastest-growing participation sport in America

The outdoor game experienced a surge in popularity during the 2020 pandemic because it could be set up in driveways, be played by all ages, and allowed for safe social interactions. That social aspect has helped pickleball’s popularity continue to rise post-pandemic. A March 2023 APP report showed 48.3 million American adults played the sport in the last 12 months.

Pickleball's ubiquity has led to a culture clash with tennis

Since the late 1800s, tennis has been the world’s premier racquet sport. But in the late 2010s, rapid growth and investment in Pickleball changed that dynamic. This Cult Tennis video explores the newly created tension between tennis and Pickleball players, both on and off the courts.

Pickleball's popularity has created a power struggle

The sport's sudden rise has led to a tumultuous landscape with battles over governance, court space, and player rights. This Sports Illustrated deep dive examines the competing billionaires vying for control, the conflicts over court usage and noise disputes, and how a second proposed Hall of Fame is dividing the sport.

Limited courts is a source of tension between pickleball and tennis players

Municipalities have rushed to accommodate the explosion of pickleball games, but sometimes they can't keep up. That's frustrated tennis players, whose courts are now often filled with people playing the sport.

The pickleball market is expected to hit $4.4B by 2033

In 2023, the global pickleball market was $1.5B. By 2023, it's expected to grow by a compound annual growth rate of 11.3%.

Carmel, California, is looking into banning pickleball

Pickleball is the fastest-rising sport in the US, but it's not without its controversies. Chief among them is noise, which Carmel, California, a wealthy enclave on the state's central coast, seeks to remedy with a ban on the sport. It would be the first in the state.

The origin of the sport's name is disputed

How pickleball got its name has been a point of contention for decades. The McCallums claim the family dog, Pickles, used to snatch the balls as they played and named it for him. Joan Pritchard, though, says Pickles didn’t join the family until after the game was invented.

Pickleball combines elements of tennis, badminton, and table tennis

In this video, That Pickleball Guy walks you through the serve and two-bounce rules, what is “the kitchen,” and teaches five ways to win a rally.

PIckleball's popularity with seniors is partially due to its health benefits

Pickleball has always been a game for all ages, but it has been particularly popular among seniors, in part because of its many health benefits, including enhancing hand-eye coordination and burning more calories than walking.

Pickleball injuries were responsible for $350M in medical costs in 2023

Unsurprisingly, picklers over 50 account for 90% of the injuries, with the most common being sprains, strains, and fractures. Experts say a substantial pregame warm-up can prevent most injuries.

Pickleball was invented in 1965 on Bainbridge Island, Washington

Bill Bell and then-Washington State congressman Joel Pritchard created the game as a way to entertain their bored children. They grabbed items they had on hand, using ping pong paddles to hit a wiffle ball over a hip-height badminton net.

Pickleball was originally intended for children

Bell and Pritchard only created the game to occupy their children's attention on vacation. As they continued playing the game, they began developing rules as-needed.

A Boeing engineer created a next-generation pickleball paddle in the '80s

When Steve Paranto kept losing in the finals of his Pickleball tournaments, he told his dad Arlen the wooden paddles were holding him back. Then-Boeing engineer Arlen used spare composite floor panels to make the first fiberglass Pickleball paddle.

A Texas billionaire created the first team-focused pickleball league

Steve Kuhn is on a mission to make pickleball the next big global sport, starting with Major League Pickleball, his team-focused pickleball league. He's turned his property, named Dreamland, into an expansive center for the sport.

See this graphic describing what different decibel levels mean for hearing loss.

The decibel scale measures sound intensity, with hearing damage occurring after prolonged exposure to sounds above 85 decibels—equivalent to a noisy lawnmower.

'Silent' fireworks are not entirely noise-free

By using a reduced amount of flash powder—the ingredient responsible for the loud explosions that fireworks make—"silent" fireworks produce displays between 70 and 90 decibels, rather than the approximately 175 decibels heard in professional displays.

One Connecticut prison is using pickleball for rehabilitation

The Pickleball for Incarcerated Communities League started in 2023 at the MacDougall-Walker Correctional Institution in Hartford, Connecticut, but has already expanded to other facilities across the state. Inmates say it's been transformative. The program has plans to expand to other states.

Why professional tennis players are so picky about balls before serving

Just as swimmers shave their bodies before competitions to swim faster, experiments show that tighter, less fluffy balls experience less drag forces when moving through the air and thus produce faster serves at the cost of less control. Players may select a fuzzier ball in scenarios that call for safer, more cautious play.

Tennis balls get their bounce from pressurized nitrogen inside vulcanized rubber, made from heating natural rubber with sulfur to create molecular links that harden the material.

Variations in rapidly expanding gas and mechanical elements produce fireworks sounds

Chemical compounds designed to vibrate rapidly when ignited produce whistling, screeching sounds, while crackles and pops are created by small star pellets inside the firework, which explode one after another quickly. Fluttering and chirping sounds are produced by spinning elements that rotate rapidly as the firework ascends.

The bullwhip was the first human-made object to break the sound barrier, producing a small sonic boom heard as a crack when flicked quickly.

When struck, objects vibrate at unique rates called resonant frequencies, which makes tapping wood sound different from tapping metal, but providing objects with sound at their resonant frequency can cause them to shatter.

See what loud noises do to inner ear hair cells

This animation illustrates how louder music can affect inner ear hair cells. Damage to these cells is generally considered permanent. Hearing protection like ear plugs can reduce the level of sound entering into the ear and help protect those cells.

Every day, lightning releases several Hiroshima bombs' worth of energy into the atmosphere

If all this lightning struck one location at once, the bolt would be the diameter of the center circle of a basketball court, turning the entire court into a crater. Its heat would ignite surfaces for miles around, and its shockwave would demolish buildings.

Tennis match interrupted by 'Cotton Eye Joe'

Tennis players require extreme focus as they volley on the court, and officials typically enforce significant noise standards during play. So it was quite a shock when the 1995 hit "Cotton Eye Joe"—as recorded by Swedish Eurodance band...

Fireworks make a loud booming sound after explosion due to air expanding faster than the speed of sound.

Objects that move faster than the speed of sound—Mach 1—create shockwaves called sonic booms by building up and forcing sound waves to combine as they lag behind the object.

People with tinnitus should avoid silence—sound-rich environments distract the brain

This podcast from an audiologist discusses common questions about tinnitus. It notes that tinnitus could be described as a phantom sound associated with hyperactivity in the brain. It's linked with loud sound exposures above 85 decibels, hearing loss associated with aging and stress, among other factors.

The three smallest bones in the human body—the malleus, incus, and stapes—amplify the vibrations of sound waves by almost 20 times to help enable hearing.

The agricultural origins of paintball guns

The paintball field industry—where players compete in pseudo-battle using the (minimally) harmless guns—is worth over $1 billion annually, and it continues to grow. This fun piece breaks down the relatively recent history of the industry by...

The surprising science behind Pop Rocks

Have you ever wondered why Pop Rocks makes tiny explosions in your mouth? Well, there's actually pressurized carbon dioxide bubbles trapped within the sugary candy. This 19-second video shows you what Pop Rocks look like under a microscope.

Listen to the sounds of pulsars, which emit radio pulses up to hundreds of times a second

Just as figure skaters spin faster by tucking in their arms, these celestial objects acquire high rates of spin from the collapse of the cores of massive stars. The star's rotation spins its magnetic field, generating beams of radio waves from its magnetic poles. If either of these poles faces a detector, the signals can be picked up and converted to audio signals.

The story behind the greatest outburst in sports history

It's a line that's still perplexing all these years later: "Who do you think you are? I am!" Those words were uttered by Pete Weber, an iconic bowler who was somewhere between John McEnroe and Happy Gilmore. This oral history from the Ringer provides some context for the bizarre insult and a backstory that turns what appears to be a non sequitur into a triumphant celebration.

'Silent' fireworks have gained more interest in recent years as a quieter celebratory option.

View a collection of sound animations, which depict how a source of sound waves pushes against particles to carry energy away without matter being displaced.

Watch how your nervous system's efforts to process silence can contribute to tinnitus

Cochlear cells can be damaged in numerous ways, including aging or exposure to loud noise. If enough cells die, the auditory system can become less sensitive, prompting the brain to compensate by amplifying sound, which is likely to contribute to tinnitus.

Why pickles became a thing

Pickles began in Mesopotamia around 2400 BCE as a way to preserve vegetables amid heat (and spoilage). They spread through Egypt, Greece, and Rome, where Julius Caesar reportedly fed pickles to his soldiers, and brining was treated as a culinary art. The technique is broadly useful, as salt and water can extend the shelf life and deepen flavor for almost anything.

The collapse of gas bubbles in the joint synovial fluid causes 'cracking' knuckles.

Squeaky toys mimic prey sounds, appealing to dogs' hunting instincts

Squeaky toys provide instant feedback and gratification, and they can also prevent boredom and improve canine dental health. Some toys contain seemingly silent squeakers that use ultrasonic technology to emit sounds only audible to dogs.

A sound's pitch will seem to change if the listener or the source moves toward or away from the other because motion changes the time it takes each successive sound wave to reach the listener.

Stonehenge may have functioned as an echo chamber designed to keep ceremonies secret from outsiders.

Acoustics researcher Trevor Cox discovered that Stonehenge acts like a concert hall, reflecting and amplifying sound. This video shows Cox demonstrating the effect using a scale model inside a soundproof studio.

The most popular drum sound of the 1980s was discovered by accident

You know it when you hear it: the distinct snare drum of songs like Phil Collins' "In the Air Tonight" or Bruce Springsteen's "Born in the USA." It's called "gated reverb," and it's something most people associate, for better or worse, with the sound of the '80s. This Vox explainer breaks down how it was discovered by accident, thanks to a microphone typically used for communication that picked up additional sounds.

More than 5% of the world's population has disabling hearing loss

Disabling hearing loss is defined as hearing loss greater than 35 decibels in the better hearing ear. (For context, that means the sound of leaves rustling, at roughly 30 decibels, would be inaudible even to your better-hearing ear.) The World Health Organization's data suggests that more than 5% of the world's population has this level of loss requiring rehabilitation, which amounts to 430 million people—including 34 million children.

Micro-seismic activity has been produced from people cheering or dancing at sporting events, concerts, and other large gatherings, but scientists can easily distinguish these vibrations from natural earthquakes using seismometers.

Crackling, popping, and rustling sounds have been reported during auroras

At the altitudes where auroras take place—between 100 and 300 kilometers (62 to 186 miles)—air is not dense enough to efficiently vibrate and carry sound waves to the ground. However, one theory suggests that the geomagnetic energy behind auroras can trigger electrical discharges near the surface, which may be the cause of reported sounds.

Before 1920, during the Deadball Era, a single baseball was used throughout a Major League game, leading to a notoriously dirty style of play.

Through sonoluminescence, concentrated sound waves can produce short, high-intensity flashes of light by rapidly collapsing microscopic bubbles to temperatures up to twice that of the sun's surface.
