Oh No! not traffic noise

So Father's day weekend was unique.

I brewed beer on Friday night in the driveway and listened to 51dB of traffic noise till 2:30am, followed by 50dB early Saturday morning.  The funny thing was that about 8:30am -ish the traffic noise dropped down to 43dB and stayed that way until almost 10pm where it slowly increased.

More weirdness with the Village of Justice IL traffic noise

So from ~4pm-8pm (we were outside working in the yard) traffic noise held steady at 42dB.  42dB is barley audible and we have no problems with it. When I got back from Menards at ~9pm the noise jump to 48dB and stayed there until sometime after 1am.  The noise dropped to 47dB between 1am-5:30am when I measured it in the morning again.

Doesn't that seem strange?
