FAHU and AHU Acoustic Services in Dubai
Fresh air and air handling units are big noise sources. We keep them from disturbing the spaces around them.
Why are AHUs and FAHUs so noisy?
Air handling units house large fans that make noise through the supply and return ducts, through the unit casing into the room around it, and as vibration through the structure. Each path needs its own control: silencers for the ducts, heavier construction for the room and isolators for the fan and pipework.
AHU noise is one part of MEP acoustics; the rest of the air system is covered by HVAC acoustic services. Silencers and isolators are installed by our MEP acoustic contractors.
AHU and FAHU noise tends to show up after handover, when the plant room is above a meeting room or the unit sits next to a bedroom wall. By then the options are limited and expensive.
We review the unit sound data, size the silencers, and design the plant room construction and vibration isolation so noise stays where it belongs. It sits naturally alongside our wider MEP acoustics work.
What's included
Sound power review of AHU/FAHU units
Manufacturer data checked against room and boundary targets.
Discharge and intake silencer design
Attenuation for the air paths to and from the unit.
Casing breakout and plant room walls
Wall and ceiling construction that contains casing noise.
Vibration isolation and flexible connections
Isolation for units, ducts and pipework.
When to call us
You don't need a finished brief. If any of these sounds familiar, let's talk.
- A plant room sits next to or above occupied space.
- An installed unit is louder than the design predicted.
- You're selecting AHUs and want the noise checked first.

FAHU/AHU Acoustics questions, answered
Can an existing AHU be made quieter?
Usually. Options include adding silencers, lining ducts, isolating the unit and improving the plant room enclosure.
Where does AHU noise travel?
Through supply and return ductwork, through the unit casing into the room around it and as vibration through the structure.
Why is a rooftop FAHU heard in the apartments below?
Mostly through structure-borne vibration, when the unit sits on the slab without proper springs or the inertia is too low, and through casing breakout down unlined ducts or shafts. A survey at night, when background noise is low, usually shows which path dominates.
What information do you need to assess AHU noise?
The manufacturer's sound power data by octave band for the supply, return and casing, the fan duty, duct layouts and the room types served. If the unit is installed, we also measure on site.
