Studies and calculations
Acoustic assessments
Do you need an acoustic assessment for a plant room or technology within a building? We assess noise for building permitting and KHS — a different scope than a neighbourhood noise study for a project.
Studies and calculations
Service overview
What we provide
We prepare assessments for building modifications or change of building use. We propose soundproofing for plant rooms, HVAC and technologies within a building
When you need this service
You are planning building modifications with impact on noise within the building
What you receive
acoustic assessment with evaluation and recommendations; noise control measure design
Service details
Scope and deliverables
What we provide
- We prepare assessments for building modifications or change of building use
- We propose soundproofing for plant rooms, HVAC and technologies within a building
- We prepare statements for building permitting and occupancy approval
- We link to operational measurements or acoustic calculation
What you receive
- acoustic assessment with evaluation and recommendations
- noise control measure design
- documentation for building permitting or KHS
When you need this service
- You are planning building modifications with impact on noise within the building
- Occupancy approval or change of building use is in progress
- The building authority or KHS requires an acoustic statement
- You need a soundproofing design before implementation
Documents and preparation
What to send us
- project documentation or project description
- layout plans and noise source locations
- operating schedule and authority requirement
- existing measurements or equipment technical data sheets
Typical mistakes and risks
- Confusing an acoustic assessment with a neighbourhood noise study for a project
- Assessment without link to actual operating schedule
- Incomplete project documentation of noise sources
Typical situations
- acoustic assessment for an HVAC plant room or boiler room in a building
- soundproofing assessment for a production hall or technology
- acoustic statement for change of building use
- link to neighbourhood noise study for a project
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.
