Hi PeggySue92, I am sorry to hear about your noise anxiety, it sounds really horrible!
Until I saw this post (and the 28 or so replies) I had no idea that Noise Anxiety was a thing, and now I've read through them all I've realised that I must suffer from it too. I'm glad to have found it and discovered that I'm not the only one.
Dogs barking to a certain extent I can handle - unless it goes on all night of course! - The most triggering noises for me are those really annoying bassy stereos that inconsiderate neighbours and car drivers sometimes play, and basketballs being bounced on concrete, it drives me crazy, I'm a 43-year-old bloke, but on hearing these bass noises my heart starts beating fast, and if it's a nice day I feel I have to get out of the house and do a walk to get away from the noise and take my mind off it.
I've found that on days when the weather is not good or if I'm working from home, I'll put on noise-cancelling headphones, they are an absolute godsend, but there are only so many hours that I can do that for, thankfully my partner is partly deaf from working in the aviation industry, so in the evening we will have the TV up loud (but not so loud that you can hear it outside of course) to block out the neighbours boomy bass stereos or loud car engines. Strangely I'm not affected by these sorts of noises in the CBD where I work, it's only at home where I get this type of anxiety.
I grew up in New Zealand and guess what sort of noise you hear before a big earthquake? you guessed it, BASS sound, in thinking about it this is probably the root cause of my Noise Anxiety. I like the suggestions some of the posters have put here, such as desensitization therapy, I think I am going to give that a go.
I built my house about 3 years ago, and originally I had the only house in the street, as more neighbours have moved in and started playing bassy stereos I've gone around and had a friendly conversation with them to please keep the music on but just turn the bass down or off - one particular house was a whole street away and I could hear the bass in my living room! When I knocked on their door and told them their bass was so loud I could hear it a street away, they had no idea and were really embarrassed about it, being friendly helps sometimes.
One neighbour had a barking dog, my partner and I got so fed up with it that we filled in a noise diary provided by council. Eventually, it stopped the noise thankfully.
I wish you all the best.
