"Yes, you can fix anything on your walls internally."

"Yes, you can improve the sound insulation of a party wall by installing acoustic panels, but simply fixing decorative acoustic panels directly to the wall will only provide a small reduction in noise.

For the best results, a professional system should include:

- A timber or metal stud framework fixed to the wall.
- Acoustic mineral wool insulation between the studs.
- Resilient bars to reduce sound transfer.
- Two layers of acoustic plasterboard with staggered joints and acoustic sealant around the perimeter.

This type of installation is far more effective at reducing airborne noise such as voices, televisions and music than surface-mounted panels alone.

If your main concern is improving thermal insulation rather than soundproofing, insulated plasterboard can also be installed on the party wall, although this will have less impact on noise transmission.

Before carrying out any work, it's worth identifying whether the noise is airborne (voices, TV, music) or impact noise (footsteps or banging), as the most suitable solution depends on the type of sound you're trying to reduce.

A qualified insulation or soundproofing specialist can assess the wall and recommend the most effective system for your property and budget."

"Yes, acoustic insulation panels can often be fixed directly onto a party wall to help reduce noise transfer between properties. However, the effectiveness depends on the wall type, the insulation system used, and how it is installed.

For the best acoustic performance, many systems use:
• Acoustic panels or soundproof boards
• Isolation bars or resilient channels
• Mineral wool insulation
• Double plasterboard layers with acoustic sealant

Simply fixing panels straight onto the wall can help slightly, but a full acoustic system normally gives much better sound reduction results.

It’s also important to ensure the installation does not create damp or ventilation issues and complies with any fire or building regulations where applicable.

A site inspection from an acoustic specialist or experienced contractor is always recommended before proceeding."

"Yes and I have done this myself. There are many products for this use like the JCW Acoustics Wall Liner Overlay Noiseboard 5. It really depends on what your budget is and how heavy the noise polution is. It will also depend on the age of your property as different property construction will mean a different wall thickness etc. So it's really a case of speak to a professional and or researching what products are available and what Db insulation levels they provide. I hope this helps."
