https://asa.scitation.org/doi/10.1121/1.5089219Whether it’s a granny flat, a music studio, drum practice room, home theatre or rented room, hearing thuds and clicks from someone walking upstairs is a problem. It’s even worse if you can hear them talking (and they can hear you). So this type of soundproofing is critical to a quiet life.
The first thing to realise is that acoustic foam won’t make much difference, if an at all. Carpet on top of the floor may help. In reality, the transmission loss of the floor needs to be improved. Most commonly, in timber house constructions, this is a good solution – wooden floor soundproofing
Underneath a concrete floor, adding a layer of plasterboard to the concrete will do very little. It’s better to add the plasterboard to a batten, creating a cavity, and insulating the cavity.
Make sure that other paths for sound to follow are fixed before you go improving the floor. Penetrations for lights and air conditioning, stairwells, windows, pipes etc can all allow lots of sound to bypass any work done to the floor.
Soundproofing Offices, Meeting Rooms and Consulting Rooms – Do’s and Don’ts
Don’t use soundproofing foam – There is one thing that really doesn’t work – putting acoustic foam on the walls (or any acoustic absorption for that matter, polyester board etc). If anyone tells you it will, ask them to give you before and after acoustic isolation (transmission loss) figures, and I bet you they can’t and wont.
Don’t take advice form those not qualified – Similarly, if the friendly builder/handyman/plasterer tells you they know what to do, ask them the same thing as the foam guys and they will have no idea. Would you spend time and money on a gut feel??
Do engage an acoustic engineer – It is a complex problem that requires assessing all noise transfer paths and bringing them to a common level that is sufficient to stop the level of noise that needs to be isolated. This includes, doors and door seals, walls, ceilings, glazing, air conditioning ducts etc. For example, there is no point making a wall highly soundproof if there are drop in ceiling tiles as the sound easily travels up and over the wall.
