Okay, so I’ve been obsessed with this whole “loudest indoor arena” thing. Seriously, it’s a rabbit hole I went down, and I had to try measuring it out myself. Here’s how it went down:

Gearing Up
First, I needed a sound level meter. I didn’t want to spend a fortune, so I grabbed a cheap one online. I know, I know, it’s probably not super accurate, but it’s good enough for a fun little experiment, right?
My Tools:
- Cheap sound level meter (from online store)
- My phone (for recording and taking notes)
- My very enthusiastic friends
The Experiment
We picked a local basketball game. It wasn’t a huge arena, but I figured it would get pretty loud during the game. I positioned myself near the center of the court, trying to get a good overall reading. I also made sure I had my friends.
Once the game got going, the sound started increasing! I started taking readings during timeouts, big plays, and whenever the crowd really erupted. I used my phone to record short video clips, just to capture the atmosphere (and the noise!). I jotted down the decibel readings in my notes app, along with a quick description of what was happening at the time (like “three-pointer!” or “foul called!”).
Man, it got LOUD. Not ear-splitting, but definitely up there. The highest reading I got was during a crazy dunk in the last quarter. The crowd went wild!

The Results (Sort Of)
My highest reading was something like 105 dB. I’ve done a check online about the world’s loudest, and that’s definitely not a record-breaker, the numbers are so much higher than what I had. But honestly, I think my little meter probably wasn’t capturing the peaks accurately. Plus, a smaller local arena isn’t going to compete with a massive NBA stadium.
I compared my notes and recordings. It was cool to see how the sound levels correlated with the action on the court. The cheers, the boos, the music – it all added up.
What I Learned
This whole thing was more about the experience than getting a perfect measurement. Here are my basic steps
- It is loud: Even a smaller game can get your ears ringing.
- Crowd power: The energy of the crowd definitely impacts the noise level.
- Gear matters: If you’re serious about this, invest in better equipment.
I might try this again at a bigger game sometime, just to see if I can get a higher reading. Maybe I’ll even invest in a slightly better meter. For now, I’ve got a newfound appreciation for just how loud a sporting event can get!
