It would be nice to switch from day to night time.

The shown level is currently the LA50 which is a median level over the week.

The future noise level attached to each hexagon will be la50, laeq and lden (day, evening, night) . In order to display "night time", we have to compute/store also the ln level.

Then in the "layer" choice dialog we will have la50, laeq and lden, ln

Do you agree @Picaut ?

Yes, I'm agree. This can be done easily, since Laeq and Lden are computed from Laeq1s.

I think the name of the layers must be Day sound level, Night sound level ...
