TBH, we live fairly remotely anyway, but we have noticed the complete and utter silence at this time of night - there is absolutely no distant traffic noise. All you can hear are owls and deer. It's so quiet your ears actually ring.
Earlier today we had a woodpecker drumming away, which was lovely. And you can hear the buzzards and red kites from a massive height.
I had my first day working outside today. It was wonderful sat outside with just birdsong around me.
