We can't hear the noises. Something like the Apple Watch noise monitoring would be great as we could say "see, the decibels haven't gone above x in the last week" but as far as I can see it doesn't give you this info over time
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.
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
