Measurements
Noise measurement and acoustics
Noise complaint, occupancy approval or authority requirement? We perform field noise measurement and acoustic calculations according to noise sources and protected areas in the neighbourhood.

Service details
Scope and deliverables
What we provide
- We measure LAeq and LAFmax during normal operation in the field
- We assess transport and technology noise on site
- We verify the effectiveness of noise control measures after implementation
- We measure noise from HVAC, heat pumps and plant rooms
What you receive
- noise measurement report
- acoustic statement on technologies within a building
- noise study with measure recommendations
When you need this service
- Building permitting or occupancy approval is in progress
- You are addressing a noise complaint from operation
- You need a noise study for EIA or project change
- You are assessing noise from a heat pump, HVAC, cooling or industrial site
Documents and preparation
What to send us
- noise source locations and operating schedule
- building authority or KHS requirement
- layout of nearest protected development, transport and day/night operating mode
Typical mistakes and risks
- Measurement at an unsuitable time or without considering operating mode
- Confusing measurement and computational study for a new project
- Incomplete description of noise sources and operating schedule
Typical situations
- noise measurement for occupancy approval or change of use
- noise study for a heat pump, HVAC or cooling system
- noise study for an industrial site with day and night operation
- verification of a noise complaint from technology or transport on site
- acoustic assessment as an EIA or building permitting appendix
Frequently asked questions
When do we need noise measurement?
Order noise measurement for occupancy approval, complaints, technology change, new equipment, workplace inspection, verification of measures or on instruction from KHS or the building authority.
What is the difference between noise measurement and a noise study?
Noise measurement verifies the actual state at a specific location and time. A noise study evaluates an expected or modelled state — for example a new technology, industrial site, transport, HVAC, heat pump or operational change.
What standards apply to noise evaluation?
It depends on whether the noise is at the workplace, in a protected outdoor area, in the protected outdoor area of buildings or in the protected indoor area of buildings.
Who is responsible for ensuring noise does not exceed hygienic limits?
A person who uses or operates machinery, equipment or a facility whose operation generates noise is obliged to ensure by technical, organisational and other measures that noise does not exceed hygienic limits in protected areas.
Can noise be addressed before technology installation?
Yes. Before installing technology, prepare a noise study or acoustic assessment — this allows timely adjustment of source location, output, operating mode or noise control measures.
