I have just moved into my first home, a top floor Victorian era tenement flat. There is really old brown swirly carpet throughout and I was planning on putting down laminate in living room, hall & kitchen/diner but my mum has been freaking me out telling me that the laminate is really noisy and my downstairs neighbour will hate me 
Originally l had planned to have laminate underlay laid on top of the original carpet underlay but the shop l am buying the flooring from has told me this isn't a good idea as they are different kinds of underlay? I have purchased 5mm thick underlay but have been looking online and see that there is audio reducing underlay that can be used, does anyone have any recommendations?
I live alone, no kids and l am generally very quiet and wear slippers indoors but still keen not to upset my new neighbours. The downstairs neighbor is an older retired lady and l get the feeling she could be difficult if l upset her
