Indoor sound level measurements allow us to determine one key thing: whether installation noise falls 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 decisions, negotiations with the general contractor, or an effective defense against claims.

What exactly do we measure?

We take a close look at a building’s "nervous system." We examine noise reaching rooms from technical equipment and installations, including, among others:

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

• Heat pumps, heat exchanger stations, and heating substations.

• Sanitary risers and compressed air systems.

• Elevator machine rooms and door drives.

• Chiller units and commercial equipment.

Our methodology is based on the ISO 16032 standard, which allows us to unambiguously 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 a manufacturer’s declaration a trap?

A device certified in a catalog as "extremely quiet" can become a source of nuisance noise in a completed building. Why? Because the final result depends not only on the device itself, but on the way it is installed. Lack of vibration isolation, incorrectly designed duct routes, rigid connections to the slab, or unsuitable volume of the installation shaft can ruin even the best equipment parameters. What a device sounds like on paper is different from reality.

When are our measurements essential?

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

• Technical acceptance (Due Diligence): Before final handover of a facility or payment of the last tranche, the investor must be sure that installations meet standards. Field measurement is hard evidence that verifies what the design does not guarantee—namely, workmanship quality.

• Complaint diagnosis: An office tenant 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, developer, and equipment manufacturer.

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

Where do we work?

We conduct studies in environments requiring the highest acoustic standards:
Premium apartments and flats, Class A office buildings, hotels and accommodation facilities, schools, medical institutions, and public utility buildings. We work both in newly constructed facilities (before acceptance) and in modernized ones with existing noise problems.

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, comparison with the strict requirements of PN-B-02151-2, precise identification of the noise source, legal and technical assessment of compliance with the standard, and—most importantly—specific corrective recommendations (what to replace, how to insulate, and why).
