>use a decibel meter on their phone to measure how loud

Phone microphones are not calibrated for this and the apps just spit out completely wrong numbers. They show relative noise changes fine but one phone could show the same sound at a higher or lower db rating just because the mic is a little more amplified or something.

The Apple Watch actually is calibrated for this and has a built in app which shows noise levels quite accurately.
