Determination and evaluation of noise

Noise levels are measured or evaluated in a standardised manner in order to enable subsequent comparison of the measured data with the legal requirements. This page contains an overview of the relevant documents on the determination of noise levels.

Noise is unwanted sound.  Noise emissions describe the processes at the noise source.  The noise then propagates from the source to areas in which people are affected where it can be perceived as onerous.  Noise in areas in which people are affected is referred to as noise immissions.  Emissions and immissions are determined on the basis of clearly defined criteria that are comparable and reproducible.

Noise levels can be determined by measurement or calculation.  In order to enable assessment in line with noise pollution regulations, the specific characteristics of the sound level (time of occurrence, pulse and tonality content) are analysed to form a rating sound level Lr that can be measured against the noise exposure limits.
