I live in a 1930s terrace - a solidly built ex-council house. I have been diagnosed with misophonia, so it's just was well that the walls mask most normal everyday noise. I feel terrible for my friends who live in newbuild terraces and can literally hear their neighbours peeing. I find noise levels much worse in the summer when everyone is out in their gardens.
My neighbours to the left smoke weed around the clock and for most of the year the smell permeating through the walls is the most frustrating thing about living next door to them. They also have a dog that frequently gets into our garden which is a nuisance, but fortunately, it doesn't bark much, so it could be worse. Their son is out of control and when the windows are open I frequently hear his parents losing their temper with him. Their language is foul and I hate my 3-year-old hearing it. A relative who frequently looks after the son yells at him in such an obscene way that it makes me feel sick. One time I snapped and told her it was vile having to listen to it. She told me to fuck off and screamed: do you not think we can hear you??!
Well yes, I've no doubt my neighbours can hear my daughter, who squeals when she gets excited. She has cochlear implants, which are programmed by her audiologist to minimise noise over 90 decibles, so she has no concept of how loud she's being. She was profoundly deaf before she got her implants last year and doesn't yet have enough speech and language skills to understand us when we plead for her to keep it down. I understand it must be annoying, but it doesn't come from a place of conflict, which is distressing to hear and to my mind makes other people's noise so much worse.
I've lived in my house for almost 20 years and my neighbours to the right had two young girls when I moved in. When they hit their teens they made a lot of noise, mostly loud music, and out-of-control parties when their parents were away, but I figured you're only young once, so didn't object. The older daughter was prone to meltdowns and had constant arguments with her mum and boyfriend but she was struggling with her mental health, so I never said anything. Now both girls have flown the nest and I rarely hear noise from that side, except in the summer, when the parents seem to make all their personal phone calls in the garden, seemingly unaware that they're sharing them with the entire neighbourhood.
We're saving up to move house. It's taking a while because I really want a detached house - both so we don't have to worry about the noise we make and so we don't have to be disturbed by the noise others make.
