Extensions

First Floor extension over existing ground floor extension - noise

Anonymous user 03/03/2024 - 3.45 PM

We have recently had an extension on an existing ground floor - we have created a new bedroom with ensuite. Below the new bedroom is the utility, cloakroom and office. If I am in the bedroom I can hear everything from downstairs - for example my husband working from home I can hear every word when he is on a call. If we are downstairs and the ensuite toilet is flushed we can hear that in the utility and if the shower is being used it sounds like water is hitting the ceiling - my question is, should the noise be that loud? I expect some noise to carry but not to be able to make out every exact word etc! Should I be going back to the builders? **Should they have fitted acoustic flooring? Is that normal? thank you

Are you a tradesperson and able to answer this question?

Not enough insolation in the floor or wrong type of insolation used

You need acoustic insulation between the floor joists to stop the noise coming through.

It's not uncommon for some noise to travel between floors, but based on what you described, it sounds like the level of noise is excessive and could be a concern. You should consider going back to the builders and discussing the issue with them. In terms of soundproofing solutions, one option is to install acoustic flooring. Acoustic flooring is designed to reduce noise transmission between floors and is often used in multi-story buildings, hotels, and other commercial spaces. It may also be suitable for residential properties where noise is a concern. There are several types of acoustic flooring available, including underlayments, resilient channel systems, and specially designed floor coverings. The best option will depend on the specific circumstances of your home, including the type of subfloor, the type of noise, and the level of soundproofing required. When discussing the issue with your builder, ask them if they considered acoustic flooring during the planning and construction phases. If not, ask if they can retrofit the floor with acoustic flooring or offer any other solutions to reduce the noise transmission. If the builder is not able to help, you may want to consider consulting with a soundproofing expert to find the best solution for your specific situation.

The problem is definitely either a lack of the required amount of insulation/sound proofing or it's not in the gap between floor joists at all!! I had the same problem with a middle floor flat that I have recently renovated. The sound transfer between the above and below flats on different floors was really noticeable until I lifted the floorboards and full filled the 300mm floor joists with a sound and fire proof insulation which has made a massive difference.

To reduce the sound you need sound proof and fire proof insulation and make sure the floor boards are correctly installed And I would re plaster with another layer of plaster the downstairs ceiling It might help reduce the sounds. Or if the ceiling it’s high enough add another sheet of plasterboard on and then plastered it again.
