More information about the service can be found here >>.
📐 What is included in the service?
This service includes:
-
Sound measurement of up to 4 rooms
(for example one sender room + three receiving rooms) -
Subsequent reporting with results and assessments
If there is a need for more rooms or more time, this will be invoiced at the current hourly rate.
🎛️ Measuring equipment and method
We use class 1 laboratory-grade measuring equipment from Norsonic – among the market’s most precise and recognized instruments.
-
When measuring airborne sound, a multidirectional sound source is used in the sender room. The sound level is then compared with measurements in adjacent rooms.
-
For impact sound, a mechanical beating machine is used in the sending room (typically the floor above) and the sound level is measured in the room below.
📊 What does the measurement give you?
-
An accurate picture of existing sound insulation
-
Ability to assess the need for measures before upgrading
-
Evaluation of effect after installation of soundproofing materials
-
Decision basis for any further improvement of the isolation
This service is suitable both for those planning sound insulation and for those who want to document the effect of measures already implemented.
If you want measurement combined with advice or design of measures, we are happy to help!
Gorm Sørensen, technical manager, shows how we set up the equipment from Norsonic for measuring airborne noise
When measuring airborne noise, a multi-directional loudspeaker is used in the sender room, where the noise value (R´w) is specified by calculating how much noise is transported to the receiver room.
When measuring impact sound, a beating machine is used that sends vibrations into the floor using five calibrated hammers. Next, the noise level (L´n,w) is measured in the room below.
