For three years, our property management company used the same general contractor for every fit-out job that came with an acoustic component. Soundproofing was treated as a line item on a bigger scope — never the main event, never anyone’s specialty.

We didn’t question it until a client complaint forced us to.

The job that exposed the gap

We manage a mixed portfolio across Dubai — villas, a few boutique offices, and a handful of high-end apartments. One client, a music producer renting a Downtown apartment, complained that sound from his studio was bleeding into the neighbouring unit despite us having commissioned “acoustic treatment” during the renovation eight months earlier.

I called our usual contractor to ask what had gone wrong. The answer was vague — something about the panels needing time to “settle.” That’s not how acoustic treatment works, and on a colleague’s recommendation I reached out to waseemtechnical for an independent assessment of what had actually been installed.

What they found explained everything.

What “general contractor acoustic work” actually looked like

The panels installed in the studio wall were decorative acoustic foam — the kind sold for home recording on a budget, with an NRC rating nowhere near sufficient for inter-unit sound isolation. There was no decoupling between the stud wall and the neighbouring unit’s wall, no mass-loaded vinyl layer, no addressing of flanking transmission through the floor.

In other words: someone had installed acoustic-looking material without addressing acoustic physics. It looked like a soundproofed room. It was not one.

A few patterns we recognised once we looked back across other jobs the same contractor had done for us:

•       Acoustic scope was always subcontracted to whichever fit-out team had spare capacity that week — not a dedicated specialist.

•       No pre- or post-installation sound testing was ever performed. We had no data confirming the work had actually achieved anything.

•       Material selection was generic across every job — the same foam panel spec regardless of whether the brief was a home theatre, a music studio, or an open-plan office needing speech privacy.

•       Flanking paths — floors, ceilings, shared ducting — were never part of the conversation. Only the visible wall.

None of this was malicious. It was a general contractor doing what general contractors do — treating a specialist discipline as a generic finish.

What a dedicated acoustic specialist actually changes

The difference started with the assessment itself. Waseem Technical’s team measured sound transmission class across the shared wall, tested reverberation inside the studio, and identified the flanking path through the ceiling void that the original work had never addressed.

The remediation plan specified mass-loaded vinyl with a decoupled stud wall, proper acoustic seals around the door and any penetrations, and a ceiling treatment to close the flanking path. Every recommendation came with the physics behind it, not just a product name.

It read like the work of people who do one thing and take it seriously — not a team picking up acoustic work between drywall and painting jobs.

The result, and what we changed going forward

Remediation took nine days. Post-installation testing showed a measurable drop in sound transmission between units — confirmed with data, not just “it sounds better now.” The client renewed his lease two weeks after the work was completed.

What stood out across the project:

•       Dedicated acoustic expertise, not a subcontracted afterthought. Every recommendation was grounded in measured data and acoustic principles specific to the space — not a standard package applied regardless of the brief.

•       Testing before and after, with numbers attached. We finally had proof the work had done what it claimed to do — something our previous contractor never provided on any job.

•       Flanking paths were part of the scope. The ceiling void that had been ignored for eight months was identified and closed in the same project.

We’ve since moved every acoustic-related scope in our portfolio away from general contractors and over to a specialist. If you manage properties or are planning a fit-out where sound isolation actually matters — a studio, a home theatre, a shared-wall office — it’s worth looking at their Acoustic Wall Panels Services in Dubai rather than folding it into a general renovation scope.

What I’d tell other property managers

Ask whoever is quoting your acoustic work whether they test before and after. If the answer is no, you are buying a finish, not a result.

And ask specifically about flanking paths — ceilings, floors, shared ducting. A wall can be perfectly treated and sound will still travel around it if nothing else was checked. That single gap cost us eight months and a client’s trust before we caught it.
