Change the room your bedroom is currently, to one at the back. Use industrial strength motorcycling earplugs but do remember to clean them regularly to prevent ear infections. Go out for some nights out to Clapham or Brixton or Putney and be grateful for the bus home. If - while on the bus - you think it is very noisy (get off at the stop PAST your house so you know) - ask the driver why he drove so noisily and/or write to TfL as above (Kensington post) and explain your thoughts to them. Best wishes.
