My wife and I live in a terrace house with our 12 month old son and small (quiet) dog. We've been living here for 3 years now and everything has been great but we just got new neighbours 4 weeks ago. 
The new neighbours consist of a mum, her boyfriend and her 3 teenagers. They are noisy ALL the time. They slam doors, stamp about and play loud base heavy music sporadically throughout the day from about 7am till 11pm. Sometimes for hours on end. It is driving us crazy. We have spoken to the mum twice and both times she has shouted to the kids to turn it down, which they have, just for it to start again 10 mins later.
Today they have woken our son up twice in the space of 1 hour by slamming the front door when leaving. The second time I opened our door and politely asked the teenage boy if he HAD to slam the door EVERY time he leave? he just grinned and said he can do what he wants along with some other mouthy stuff -so I told him to fuck off- and then got in his dads car. His dad then sat outside for 10 mins with his window down staring at me through our window. I went out and asked him to leave and he started shouting at me in the street about how rude I was and I needed to learn some lessons on how to be polite. This made me laugh.
I knocked on next doors door to try to speak to them about the noise but the boyfriend was the only adult in and when I said base can be turned down he said he can't hear it. Even though I can hear it on our ground floor when they are listening to it on their 2nd 
Apparently I have to deal with it because that's what living in a terraced house is like. The old neighbours were never this loud and they we're going and had parties!
Sorry if this makes no sense. I am very angry and have a teething and very overly tired baby sitting on my lap.
