Why the fuck should the OP get ear defenders/earplugs, or move into another room?
Or get soundproofing?
These neighbours sound like utter cunts. We lived in a 2 bed semi in the late 1990s, and a lovely elderly couple lived there when we moved in, and were there for the first 3 or 4 years we were there. Then they left, and a couple moved in their mid 40s moved in.. (no kids.)
Basically, they forced us to move because they used to go out to the pub every Friday and Saturday night, and leave the music playing full blast from 7pm until midnight when they came back, (this was to 'deter burglars' apparently.) 
We asked them several times to be more quiet please, because our DD (only 5 or 6 at the time) went to bed at 7.30pm and couldn't sleep with the music pounding until midnight. And we couldn't hear our TV properly!
We didn't complain to the council, because they were such horrible, rude, anti-social arseholes, (with noisy weekend BBQs every weekend of the Spring and Summer too, and loud music playing in the week sometimes too,) that we wanted to sell up and move. A neighbour dispute being officially registered would have had to have been declared.
Our house sold within a couple of months. A private landlord bought it. We had the last laugh too, because 2 couples moved in, who were in their 20s, and according to someone who lived in the street (who we bumped into a few months later,) the noise levels from these 2 couples was fierce, and the old neighbours who forced US out, put their house up for sale 4-5 months after we moved out!
My friend is currently having issues with a new neighbour who moved in, back in January. A couple in their late 30s... They work during the day, but have the TV on loud, with a sound bar on, thudding through the walls every evening for 4 or 5 hours. On a Friday night (and sometimes Saturday too,) they have loud music thump-thump-thumping through the wall until 2am. They even have a TV and a stereo in the bedroom, and sometimes go into the bedroom at midnight, and have the TV or stereo on til 3am, blasting through the wall. (They live in a small 2-bed, semi-detached house built in the late 1990s.)
When my friend has knocked to ask them to turn it down, they don't answer. She popped a note through 2 weeks ago, and since then, it's been even louder.
Utter cunts.
She is currently recording the noise, and keeping a diary, on the advice of a police officer friend.
I don't know why some people are such horrible bastards, and so inconsiderate and rude. Probably the same type who throw stuff out of the car window, and leave their rubbish at the park, let their dogs loose off the lead, and let their dogs shit everywhere and never pick it up. Horrible, self-serving, entitled, selfish cunts.
My friend's police officer friend, also said that around 20% of call-outs/jobs on his shifts are neighbour complaints/disputes, often caused by excessive noise. As I said, I don' know WHY some people are like this. 
@Noisyneighbourhelp12 YANBU obvs! Not sure where you get a noise measuring app. Hope someone can advise you. My friend is just using a mic on her mobile phone, and an old fashioned tape recorder.
