Noise complaints are the background hum of Maltese apartment living: the street café below, the neighbour's television through the party wall, the upstairs heels on tile at midnight. Soundproofing is a field full of overpromises — so here is the honest hierarchy of what works, what it costs, and what physics refuses to allow.
First, diagnose the noise
- Airborne noise — voices, TV, traffic — leaks through weak points: apertures, gaps, thin walls, and travels wherever air travels.
- Impact noise — footsteps, dragged chairs, the upstairs washing machine — transmits through the structure itself, and is far harder to fix from below.
Which one you have decides everything, including whether your money should go to your flat or to a diplomatic conversation upstairs.
The hierarchy of fixes (best value first)
- Seal the air paths. Sound follows draughts: perished aperture seals, gaps under doors, uncovered keyholes, the service penetrations behind kitchen units. A handyman sealing visit (€60 – €150) is the cheapest decibel reduction available and pairs with the winter draught-proofing you should do anyway.
- Upgrade the glazing. Street noise mostly enters through glass and its frames. Double glazing with good seals transforms front rooms; where apertures are protected (Valletta and village cores — the UCA reality), secondary glazing inside the existing aperture achieves similar numbers reversibly. €300 – €900 per aperture.
- Solid-core doors where hollow doors separate you from noise — bedroom and entrance doors especially, with proper perimeter seals. €150 – €400 per door fitted.
- The independent lining wall. For a genuinely offensive party wall: a decoupled stud lining with acoustic insulation and double plasterboard, built off the wall face. This is the real treatment — and it costs 6–10cm of room depth and €60 – €120 per square metre. On typical Maltese masonry party walls it is the difference between "hearing the argument" and "hearing that there is one".
- Ceilings, honestly: impact noise from above is best fixed at the floor above (rugs, soft feet — the diplomatic route). A suspended acoustic ceiling below helps meaningfully but not magically, at €70 – €130 per square metre and a ceiling-height cost Maltese rooms can usually afford.
What doesn't work: egg boxes, thin "acoustic" foam panels (they tame echo inside a room, not transmission between rooms), and paint-on miracles. If a product promises soundproofing in millimetres, it is treating the room's acoustics, not your neighbour.
Sequencing and expectations
Do the cheap layers first — sealing plus glazing solves most street-noise cases outright. Reserve linings for the one wall that earns it. And set expectations by construction: Maltese solid masonry already outperforms lightweight builds for airborne sound; what it transmits enthusiastically is impact, which is why the upstairs-tiles problem is the island's hardest case — and why it is often cheaper to gift the neighbour some felt pads than to rebuild your ceiling.

Frequently asked questions
How do I reduce street noise in a Malta flat?
Seal every air gap first, then address the glazing — double glazing or reversible secondary glazing behind protected apertures. Those two layers solve most street-noise complaints; walls are rarely the entry point.
Does soundproofing a party wall work?
A properly decoupled acoustic lining wall works well against airborne noise — at the cost of 6–10cm of room and €60 to €120 per square metre. Thin stick-on panels do not; they change the room's echo, not the neighbour's volume.
Can I soundproof against footsteps from upstairs?
Only partially from below — impact noise travels through structure. A suspended acoustic ceiling helps; soft flooring installed upstairs helps more. It is the one noise problem where the conversation is genuinely more effective than the construction.
