By the spread of environmental noise mapping and real-time noise
monitoring techniques a new demand has appeared for a noise map
that represents the actual noise situation by its regular
updating. With the help of the propagation modeling we are able
to determine the noise immission’s spatial distribution while
with the help of monitoring we can determine its time
distribution. Therefore, the combination of the two techniques
is obvious. However, multiple theoretical and practical problems
have risen during the realization. The present paper describes a
hypothesis about the determinability of the noise immission
level at every point in a certain area with the source-selective
noise immission data of a reference point; and another
hypothesis about the possibility to measure noise immission
source-selectively by determining the dominant sources of noise
events using observations of the surrounding environment. The
paper verifies the above hypotheses and presents an experimental
realization of them in a real environment.
