I rent a room in a flat above the shop. The problem is that the shop's fridges are buzzing so loud that I can hear them in my bedroom. It's really annoying and it's really affecting my sleep, I can even hear it during the day. I asked the owner to do something about it, so he fixed the fan motor however I can still hear the humming - it isn't as loud as previously though.
My question is, is there any way I can soundproof my floor? I cannot replace the floors and put a carpet on them as I'm not the owner. I bought a huge rug and it helped a bit but I was thinking of getting some thick underlay. Do you reckon it will be a good idea? Are there any alternatives? I'm desperate!
Thank you in advance!
