Environmental noise is unwanted sound and vibration coming from a plethora of sources, among them industrial plants, road and rail traffic, construction work, and aircraft. Add to these sports events, shooting ranges, leisure parks, etc, and you have noise from many different sources, each with different characteristics and posing specific problems for the professionals who have to assess them. The way the problems are dealt with differs immensely from country to country and is very much dependent on culture, economy and politics. We offer solutions to cover all demands from level checks to in-depth analysis, from measurement or prediction, to post-processing and reporting.

Controlling and monitoring railway and train noise in residential and urban areas is a critical function of a railway. The noise generated can be dependent upon the engine, rail cars, rail construction, train speed, and the horn. Modern high speed trains have also created new levels of high frequency noise that create an acoustic disturbance that sounds like an aircraft going by.
