Research on local conditions influencing noise propagation

Vibrocomp ME recently conducted a research on local conditions that influence significantly the noise propagation. Meteorology, atmospheric absorption and ground attenuation typical for the Gulf States have been investigated and modelled. The research consisted of a number short and long term noise monitoring measurements, meteorological data collection and automatic traffic counting. Measurements were carried out at different road types in different built-up areas (free field also). Vibrocomp ME has equipment to carry out short term (1 day to 1 month) and long term (1 month to 1 year) noise measurements, meteorological and traffic data collection. The result is a database on factors influencing the noise propagation

This database is needed as input data for accurate (taking local conditions in account) noise modeling in the GULF.
