Sound proofing walls leads

I can hear all the conversation from my downstairs neighbour I require soundproofing the floor if possible?

Offices share a wall at our house. We work from home.
Seems like no insulation. In shared plasterboard wall.
Rented house so wanting to keep costs low and will need permission from landlord.
Approx 2m x3m dimensions.
Can hear each other talking between the wall.
A neighbour told me there is hardly any insulation in these houses. A small cardboard layer apparently.
Looking to see what price and effectiveness of a treatment would be.
Thanks

Living room ceiling needs sound proofing

My neighbour is constantly complaining about the sounds of us walking around the house and other daily noise. I would like to replace all of the carpets with soundproof ones entirely but I need a payment plan rather than to pay ina lump sum as money is tight.

SOUND PROFFING THE GROUND FLOOR IN A RENOVATED C1860 STONE BUILDING.

I need to soundproof the floor of a bedroom 8x9 m2, in a Victorian terraced house.

Soundproofing 1 bedroom which is above and adjacent to neighbours tv. Sound is carrying throughout the entire house but the bedroom needs to be soundproofed.

I’m looking for a professional soundproofing solution for a flat in a Victorian terraced property in South London.
Issue:
I’m experiencing clearly audible vocal noise (speech/raised voices) from my neighbour through a brick party wall. The wall includes a chimney breast from an old, closed fireplace, and there is currently a vent in the chimney breast, which I suspect is acting as a sound path.
What I’m looking for:
• A site visit / survey to identify direct transmission and flanking paths
• Advice on treating the chimney breast and vent safely (fire-safe, condensation-safe)
• A high-performance wall solution (e.g. independent stud wall or isolation clip system)
• Target outcome: screen out voices so speech is no longer intelligible
Property details:
• Victorian terraced building
• Noise appears to come directly through the wall, not via floor or ceiling
• This is for a [bedroom / living room – delete as appropriate]
Please could you advise:
1. Your recommended wall build-up (materials & thickness)
2. Expected realistic dB reduction for speech
3. Whether chimney breast / flue treatment is included
4. Approximate cost per m²
5. Lead time and duration of works
Many thanks,
Tim
