Why Does Small Noise Shake My Peace So Deeply?

Lately, even the tiniest sounds at home seem to break my concentration and steal my calm.
Whether it’s the kids playing or the neighbor’s dog barking, I find myself more restless than usual.
I wonder if age makes us more sensitive to these little disturbances or if it's just a sign that my mind needs a bit more rest.
Anyone else feel this way?
It’s funny how noise can weigh so much heavier than before!
