Winter is the time for sound emission measurements!
During the winter months, suitable wind conditions are regularly available. Agricultural activities are also on hold. This facilitates the precise recording of turbine noise, thereby increasing the accuracy and reliability of the measurements. Hence our clear recommendation: Make the most of this time to carry out sound emission measurements!
What is important to note about this test: The sound emission measurements take place in the immediate vicinity of the wind turbine and verify whether the planned and approved sound power levels are being adhered to.
What happens if the measured sound power level differs from the approved level?
- Levels below the authorised sound power levels are often found due to manufacturer’s safety margins and lead to a reduction in the stated noise reduction. This enables increased output whilst simultaneously complying with the operational emission limits defined for the protection of local residents.
- Exceedances can sometimes occur due to acoustically relevant defects. In such cases, it must be checked whether the exceedance at source also leads to an exceedance of operational emissions at the point of exposure. If this is the case, appropriate measures must be taken.
Hence our tip! Check now for any conditions in your authorisation notice and schedule SE measurements promptly during the winter months!
