The measurements taken by the watch can be viewed over time in the Health app on iOS. Try image searching for "Environmental Sound Levels" "iOS" "Health" to get an idea of how it looks. e.g. here is a screenshot: https://www.idropnews.com/wp-content/uploads/2023/04/Apple-H...

It sounds like this iOS app can write noise levels to the Health app too: https://apps.apple.com/us/app/niosh-sound-level-meter/id1096... so maybe that could let you test drive this if you don't already have the watch.

This is great, thanks!

I have a watch and just checked. There is quite granular data there (readings about every 30 seconds)

Nothing jumps out but I will dig through it

Huge thanks for the pointers
