Note: Every 10 decibels(dB) reduction in noise level is roughly perceived as a halving of the perceived loudness. So, for instance, if you have a sound that measures 70dB and it decreases to 60dB, it would sound about half as loud to the human ear. Decibels explained.
NOTE: When the panel is installed, the plasterboard layer faces the room, and the acoustic membrane on the back of the board adheres to the wall.
- Ensure the surface you are applying the panels to is in good condition, and make good any remedial work to the existing wall to ensure it is flat and secure before you attach the panels.
- Remove skirting boards and coving and extend electrical outlets; these can be reinstated once the work is complete.
- Begin the installation by installing the bottom row of boards. Leave a 2-3mm gap between the floor and the boards using 2-3mm packers or an equivalent to support the panels.
- Apply the Noisestop Acoustic Panel to the walls using Hammer Fixings. Fix the panels using nine Hammer fixings per board. These fixings are suitable for most solid walls. Always check before the installation to ensure suitability. Screw the panels onto timber or metal studs with drywall screws.
- Use acoustic sealant between each panel as you butt them together.
- Leave a 2-3mm gap around the wall’s perimeter to reduce flanking sound transmission, and apply an acoustic sealant to fill the gap once the installation is complete.
- Cut the panels using a hand saw or a circular saw.
- Skim plaster or tape and fill the tapered edges.
- Upon completion of the soundproofing, reinstate the skirting and coving.
- When reinstating electrical outlets, use acoustic putty pads inside recessed back boxes.
Finishing soundproof panels
- Taping and jointing -Apply joint tape (paper or mesh) over all joints. Use jointing compound to fill and feather out over the tape.
- Skim Plastering – Apply a thin coat of finish plaster (usually 2–3 mm thick) over the entire plasterboard surface.
- Plasterboard Direct Decoration (No Skim) – Tape and joint as usual. Sand and apply a sealer or mist coat. Paint or wallpaper directly onto the plasterboard.

Wall soundproofing FAQS
- Mass-loaded vinyl (MLV): A dense, flexible material that blocks sound.
- Soundproof panels: High-density soundproofing boards that block sound.
- Acoustic insulation slabs: Help absorb sound within wall cavities.
- Decoupling clips: Sound-isolation clips decouple the existing wall from the new wall, reducing vibration noise.
- Soundproof Plasterboard: Denser than standard plasterboard, making it better at blocking airborne sound.
Soundproofing can significantly reduce noise, but it’s unlikely to block 100% of sound. Low bass frequencies or very loud sounds may still get through, but the overall noise reduction can be substantial. To ensure you get the most from your wall soundproofing solution, consider other areas of the building that may be weak spots and allow sound to pass through. See our flanking noise answer below.
Common flanking noise paths.
- Ceilings and floors, joists with empty cavities
- Side walls that connect to the soundproofed wall
- Studs and framing inside the structure
- Doors and windows
- Electrical outlets, vents, and gaps
