Looking for some help & advice regarding floor soundproofing. Daughter has just bought a first floor flat and there is a lot of noise from the flat below, particularly voices.
Today I've lifted the carpet & underlay to find a lot of gaps around the old floorboards. There is also an empty void between floor & ceiling of flat below so some insulation/ soundproofing is definitely needed.
I've had a look about and I'm thinking a covering on top of the floor is probably the best bet, having seen some rubber mat type that seals the floor and supposedly reduces noise levels by 50%.
However as always these mats are pretty expensive so I'm wondering if anyone has done a cheaper DIY solution? I'm thinking boards with some cheaper sound deadening underlay may work?
So any & all advice welcome. Tia.

There is a board screwed to underside of joists but various holes cut when flat has been renovated for heating pipes etc. This allows you to see the void above downstairs ceiling.
I have watched a couple of yt videos describing what you suggest but I'm unsure which method is best ie rockwool & new thick board flooring or mats onto original floorboards.

Great advice thanks everybody,
I had another look this morning and as coolhands says there is too many pipes and wires to try and fill void.
Think I'm going to try filling all gaps, there is a lot which is probably a big part of the problem. I'm then going to try the mass vinyl as suggested on top followed by good underlay.
