Small house, so rarely quiet going on here. But I need to write silently, so I've developed ways for quietness, and use it for God-time too.
"noise-canceling headphones." Doesn't really cancel noise, but much quieter. (Ear buds don't work.) Worse comes to worse they have spongy things to put in your ears at your local drug store.
Eyes closed. Really stops the visual distractions.
Check if the stove is on, because burning food really cuts quiet time.
People have to sleep sometime, so late nights or early mornings means quiet.
Bathroom. Very few dare to intrude in the bathroom. (Just don't stay too long, if there is only one toliet. lol)
Unless your disabled, you are not stuck in the house. There's a whole world outside that door. If it's reasonable temperatures out, there is a nook near you -- maybe a natural setting near drainage pipes no one goes to, or a part of a park no one goes to, (in my case, because it's a bottomland, so flooded a couple of months in spring or after downpours), or behind the 7-11, because very few people go in back of a convenience store, or a car sitting in the garage, driveway, or curb. A car no one is using at the moment. I live in Philly with 1.1 million other people. I can still find a quiet place, or make one.
I needs me some quiet sometimes.
