I am planning to sound insulate my low ceiling 11 m2 room, from the noisy neighbours upstairs, without removing the old ceiling in a relatively clean and easy way. My design and materials are the following:
1. I drill will small holes on the ceiling and inject expanding foam, to reduce echo withing the joists:

2. Apply a layer of self adhesive Tecsound 50, sound membrane to stick under the ceiling, for airborne noise insulation (2.6 mm thick) :

3. A layer of rubber carpet underlay stapled on the ceiling under the sound membrane, for impact noise insulation (5mm thick):

4. Install acoustic plasterboard under the other two layers (12.5mm thick):

5. Use plastic plugs for the screws to attach the plasterboard to the ceiling, to further insulate the plasterboard from joists vibration:

Overall, will reduce the ceiling height only 20mm and will add around 185 k of weight.
What do you think?
