Evidence of adequate noise control can be provided by measuring the noise levels in the immediate vicinity of a facility or by making measurements according to immission categories, depending on the task description. Müller-BBM is an accredited testing laboratory according to the DIN EN 45001 standard and an officially recognised measuring facility according to Article 26 of the German Federal Immission Control Act, for the evaluation of noise and vibrations and the determination of emissions and immissions of air pollutants.

Continuous verification is possible using a long-term measurement station with telephonic data transmission.
