As I live up the hill over crawded Monaco city and because of the noise sensor chart it is possible to observe the change in activity habits.
During this period it has been a very calm period the week starting march monday 23 knowing the StayHome start here in France the 03/17 to sunday 28 of march. With an average of 45db and some low at 34db view image attached
Since then activity have increased as normal.
I attach two scree capture the first one is the stayhome and the second is about the noise during the 2019 Monaco F1 Grand Prix
