Hi Frens,
I'm in swamp sprawl and my apartment building and buildings around mine quietly lost power for 45 minutes last night. Interesting, huh? A test run? Some sort of high speed event? I live near a military base and there was also a very loud bugle call at 11 PM last night, I've heard bugle calls before from the base but I can't recall hearing one at 11 and I can't recall ever hearing one so loud.
Ears threshold changes at night while everything gets quieter (include es electronical noise, cars, ambience events, etc ), so it's normal to hear things louder, but depends always then loud how much,
To make the test you can easily put a song on hifi in the afternoon, leave it at a specific volume where you can hear it well but not so loud, notice the difference as the hours are passing, you'll keep hearing always louder
Of course sound is different at night. But I'm always in the same spot at 11 PM at night and I've never heard a bugle before at 11PM at night.
