We know the rules
Guideline values are not guesswork
Our experience has given us a thorough knowledge of the rules and guideline values that apply to traffic noise, construction noise, industrial noise and disturbance from music. We help clients, developers and property owners choose the right sound class and meet the requirements, already at the programme stage.
