Room sound level measurements allow us to determine one key thing: whether installation noise remains within strict standards or exceeds them. More importantly, we precisely identify which device or installation error is responsible for the problem. Without hard data from a certified measurement, you have no basis for corrective action, negotiation with the main contractor, or effective defense against claims.

What exactly do we measure?

We closely examine the building's "nervous system." We assess the noise reaching rooms from technical equipment and installations, including:

• Mechanical ventilation, air conditioning (HVAC), and VAV boxes.

• Heat pumps, exchanger stations, and heating substations.

• Sanitary risers and compressed air installations.

• Elevator machine rooms and door drives.

• Chillers and commercial equipment.

Our methodology is based on the ISO 16032 standard, which allows us to unequivocally assess the measured sound level against the requirements of PN-B-02151-2 – the key Polish standard defining permissible noise levels in buildings of various uses.

Why is the manufacturer's declaration a trap?

A device certified in the catalog as "extremely quiet" can become a source of disruptive noise in a finished building. Why? Because the final result depends not only on the device itself, but on its installation method. Lack of vibration isolation, incorrectly designed duct routes, rigid connections to the slab, or an improperly sized service shaft can negate even the best equipment specifications. A device sounds different on paper than in reality.

When are our measurements indispensable?

We operate where tolerance for noise ends and engineering verification begins:

• Technical acceptance (Due Diligence): Before the final handover of the facility or payment of the last installment, the investor must be sure that the installations comply with the standards. A field measurement is hard evidence, verifying what the design does not guarantee – namely, workmanship quality.

• Complaint diagnosis: The tenant of an office or the owner of a luxury apartment complains about noise. The question is not "is it loud" (because that is subjective), but "does it exceed the standard and where does it come from?" Our measurement ends the debate, identifies the culprit, and eliminates blame-shifting between the installer, the developer, and the equipment manufacturer.

• Verification of remedial effectiveness: Acoustic silencers were replaced, vibration isolation mats were added, ducts were modified. Has the problem disappeared? Post-completion measurement confirms the effectiveness of the intervention and closes the case.

Where do we work?

We conduct tests in environments requiring the highest acoustic standards:
Premium apartments and residences, A-class office buildings, hotels and accommodation facilities, schools, medical facilities, and public buildings. We operate both in newly constructed facilities (before acceptance) and in renovated properties with an existing noise issue.

Report: From diagnosis to solution

The result of our work is a comprehensive engineering document that leaves no room for speculation.
You receive: detailed measurement results, a comparison against the stringent requirements of PN-B-02151-2, precise identification of the noise source, a legal and technical assessment of compliance with the standard, and – crucially – specific corrective recommendations (what to replace, how to insulate it, and why).
