If you’ve ever spent more than 20 minutes in an indoor playground—whether you’re watching your kid zoom down a spiral slide, a group of 5-year-olds yelling over a pretend rocket ship, or teens laughing while they tackle a foam pit obstacle course—you’ve probably noticed one thing: it’s loud. Like, really loud. As an indoor playground supplier, I get this question all the time from school admins, daycare directors, and even small business owners looking to open their first play space: “What’s the actual noise level in these places, and is it something I need to worry about?” Indoor Playground
Let’s cut the corporate jargon and get real here. I’ve spent years helping build play spaces across the country, so I’ve stood in enough bouncer rooms and ball pits with a decibel meter in my hand to give you the straight scoop. First, a quick science 101 that’s way less boring than it sounds: decibels (dB) measure sound intensity. A normal conversation is around 60 dB. A busy restaurant hits about 70 dB. Lawn mowers or power tools? That’s 90 dB. And here’s the part no one talks about enough for play spaces: OSHA (the workplace safety group) says long-term exposure to sounds over 85 dB can start damaging hearing, and anything over 120 dB is painful enough to cause instant discomfort.
So what’s the average indoor playground level? From the 10 times a year I drag my decibel meter to different installations, the sweet spot (read: no one’s yelling to hear themselves talk) is usually between 85 dB and 95 dB when it’s moderately busy. But when it’s packed—like on a Saturday morning or during a birthday party with 20 screaming kids and a clown blowing a balloon animal—those numbers spike fast. I’ve measured 110 dB during a foam pit free-for-all. That’s as loud as a chainsaw or a rock concert’s front row. No joke.
Now, I know what you’re thinking: “Kids run around screaming. That’s part of the fun, right?” You’re not wrong. Play is loud, and that’s actually how they communicate, test boundaries, and work out all that excess energy. But here’s the thing that’s made me care so much about this topic over the years: hearing damage from loud places isn’t just a concert or construction site risk. It’s something that can add up over time, especially for little ears, which are way more sensitive than adult ears. Kids’ eardrums are thinner, and their auditory systems are still developing—so sounds that feel “just loud” to a grown-up can be way more harmful to them.
But before you go writing off indoor playgrounds as noisy, dangerous spaces, let’s talk about what actually causes that noise, because not all of it is unavoidable. A lot of the time, the loudness we see in many older play spaces comes from cheap, hard surfaces: uninsulated metal slide frames, concrete floors, plastic ball pits with no lining, thin fabric crawl tunnels. When sound bounces off all those hard surfaces, it amplifies exponentially. It’s like yelling in an empty bathroom—everything echoes and gets way louder than it needs to be. That’s the stuff we fix when we design a play space.
Here’s a stat I ran across a few years back that stuck with me: a study from the American Speech-Language-Hearing Association (ASHA) found that 1 in 5 kids have some kind of hearing loss, and loud noise exposure in childhood is one of the top preventable causes. That’s not something we ignore when we’re sourcing materials for our play equipment. We’ll use soft, sound-absorbing foam for ball pits, install rubberized flooring that cuts down on echo, and even spec insulated metal frames for slides to muffle the clatter of kids running up and down. We also talk to our clients about layout tweaks: separating active play areas (like foam pits and obstacle courses) from quieter zones (like pretend kitchen corners or book nooks) so kids who need a calmer space have somewhere to go.
But let’s be real—there’s a line between “healthy, fun noise” and “noise that’s actually a problem.” The key is figuring out what your specific space needs. If you’re a daycare with 10 kids a day, a lower ceiling and more soft padding might keep levels around 85 dB, which is totally safe for short visits. If you’re planning a big commercial playground that hosts 100+ kids a day for birthday parties, you’ll want to invest in more sound-dampening features, because sustained exposure to over 90 dB can start to cause stress (even adults feel tense when they’re in a space that’s too loud!) and over time, could lead to hearing issues.
I’ve had so many clients tell me, “I don’t care about the noise—kids are loud, that’s just how it is.” And yeah, that’s true. But what I’ve also seen is that when you design a play space with noise in mind, it’s not less fun—it’s better. Last year, we installed a play center in a suburb that was dealing with complaints from local parents because the noise was so bad. When we swapped out the 1-inch plastic ball pit for a 3-inch foam-lined one, added sound-dampening ceiling tiles, and separated the toddler zone from the main play area, the levels dropped by 12 dB. Parents stopped complaining, and the kids still ran around, laughed, and had just as much fun. In fact, one parent told me she could hear her kid calling her name from the ball pit for the first time in a year. That’s the win no one talks about enough.
Another thing I get asked a lot: “Can kids really get hearing damage from a few hours in a playground?” The short answer is, if it’s occasional and the level is under 100 dB, probably not. But if your play space is regularly hitting 110 dB for hours at a time (like during a 3-hour birthday party with 25+ screaming kids), that’s a different story. A study from the National Institute on Deafness and Other Communication Disorders (NIDCD) says that a single hour of exposure to 110 dB can cause temporary hearing loss, and repeated exposure over months or years can lead to permanent damage. That’s not a risk I’m willing to brush off when I’m helping a client build a space that’s supposed to be a safe place for kids.
So what should you look for if you’re shopping for an indoor playground? First, don’t just go by what looks cool. Ask about the materials: do they use sound-absorbing foam, rubber flooring, insulated metal, or fabric that cuts down on echo? Ask about layout: are there separate zones for different play types, so loud areas aren’t right next to spaces where kids might need to hear instructions or play quietly? And if you’re a client, don’t be afraid to ask suppliers about their approach to noise—I’ve had people ask me if I’ve ever measured levels at their existing space, or offer tips to tweak their current setup without redoing everything.
At the end of the day, I’m in this business because I want to build spaces where kids can be kids—screaming, laughing, running, and being wild. But that doesn’t mean we have to sacrifice their health to do it. The noise level in an indoor playground isn’t a fixed, scary number. It’s something we can design for, adjust, and manage so everyone—kids, parents, and staff—can enjoy the space without worrying about long-term effects.
If you’re thinking about opening an indoor playground, or redoing your current one, and you have questions about noise levels, materials, or layout that works for your needs, I’m here to chat. We don’t do one-size-fits-all solutions, and I’ll never sell you something you don’t need. Just reach out, and let’s figure out what’s right for you.
