I'm more sensitive to noises...especially loud ones. I mute the commercials on TV, too! There is one that I absolutely HATE! It's for a cell phone.....and there is a spider as the picture on the face of the phone....and some woman sitting at the table sees it and starts screaming. Loudly. If I see that commercial coming on I dive for the remote to mute it. For some reason that particular ad just irritates the tar out of me.
I've often wondered if it's aging. Or just the fact that I'm home all the time now without the interruptions of work, the public, noises I can't control, etc. I love the quiet. I find that when my son watches TV - and it's one of those shows with violence, cop cars, screaming, guns shooting, etc. - I just have to leave the room.
Even people talking loudly bothers me. There was a lady in the vet's office last time I was there who was speaking so loudly that the kittens in the adoption cage even hid under their blankets! I wanted to get in there with them!

Maybe she was hard of hearing....I don't know. But it was painful!
