Several noise sources result in typically higher levels of immission.
Noise calculation is done for the following reasons: Mostly, noise calculation is part of any such planning process and may become part of the decision process for physical change Environment engineering differentiates between: Each of before mentioned require different algorithms for noise calculation which have been defined over time in a number of different national or international standards.
This list of widely accepted noise calculation standards is incomplete, and new standards may be under development: NoiseScore is a mobile app for crowdsourcing community noise.
[1] Noise experts and some small specialized companies have slowly developed a limited number of calculation tools, which have increased in number and become more user-friendly, covering more application cases, and adding service elements to the noise calculation tools.
The noise calculation process is complex in input (gathering data, correctly modeling acoustic elements in the field) and from a pure compute power perspective, recently advances involved: The quality of results from the noise calculation depends on the quality of the acoustic data provided and the capability of the noise calculation engine.o take decisions.
