Noise problems?
We solve them.
Acoustic measurements, investigations and expert advice for residential, commercial and governmental clients across the Benelux. Clear reports, legally admissible, delivered within two weeks.
Noise pollution affects your health, sleep and wellbeing
Impact noise from upstairs, neighbour noise, a humming heat pump or a poorly insulated new-build: without an objective measurement, you cannot prove unlawful nuisance.
Schedule a free consultation“I hear every footstep from upstairs”
Impact noise from footsteps, children playing or furniture on laminate is the most common complaint. We measure impact sound insulation per NEN 5077.
“My new-build home is noisy”
Even new construction often fails to meet acoustic requirements. An objective measurement proves whether the contractor met their obligations.
“The neighbour's heat pump is too loud”
Outdoor unit noise may exceed legal limits. We measure the sound level at your facade and advise on sound-reducing enclosures.
“I need evidence for court or the HOA”
Our reports per NEN 5077 and NEN-EN-ISO 16283 are regularly used in legal proceedings, HOA disputes and enforcement cases.
