Sound proofing - using MDF under wooden floorboards


I have bought a top floor flat/ apartment in a house conversion. It is victorian so 100+ years old. I am installing engineered wooden floors onto the current wooden floor. I was thinking of laying MDF in between to help as a sound insulator before using an underlay. My carpenter says this wont help. Although i have it in my current flat. It seems to work where I live now, as my neighbours dont complain. Although in my current flat the base floor is concrete. He says MDF on wooden floors don't help with the noise reduction. I cant seem to find any arguments for or against this.

Can anyone offer any suggestions.

Thanks you

MDF under the flooring won't help significantly. The sound will be going through wood(MDF) then wood (floorboards), and won't be reflected back or absorbed. Sound reduction in the situation you're describing is expensive, involved, or both.

Good luck!
