Am I crazy for being someone who can't have both ears closed off

(Be warned not diagnosed) Wether im at work, paying games or just listening music i need to have one ear clear no matter what I dont know what this could mean but a minute or less after I put the other ear in im unable to anything unless that other ear is pulled outta the headphones unless its something im extremely focused on (Not a diagnosed autistic [uk laws, multi year waiting list] but multiple diagnosed friends have insinuated just not sure if it just certain or just me being weird) hoping for some insight if anyone is open to it. I just can't handle nosies that aren't controlled or predictable(for work im on a farm with minor industrialisation and i can hear a diesel forklift revving up next to my ear fine I work next to a soil hopper with ease but the second I hear a slight scrape of metal im borderline comatose I get im not officially a part of this area but some help would be very appreciated thanks
