--data describing the receptors considered (the number of receptors to pollutant immission
concentration taken into account, the height of placement of every receptor considered, landmark coordinates to a fixed point, the nature of land);
standards are based on noise quality criteria or guideline values for noise exposure to be applied to specific locations and are generally built into planning procedures (Kaklauskas et al.

At an Action Against Noise seminar at the NEC, Mr Meacher said the Sound Immission
Contour Maps (SICMs) are an important step in reducing noise pollution.
Other environmental technical standards are, for instance, emission and immission
limits for S[O.sub.2] air pollution, or the nitrate content of ground water, or the exposure of the human body to radiation, measured in REM.
Occupational noise management--Measurement and assessment of noise immission
In combination with the Immission
Frequency Distribution Model (IFDM)] using emissions from line sources and point sources, the model chain provides daily [PM.sub.10] and [PM.sub.2.5] values on a 25 x 25 m receptor grid (Lefebvre et al.
Additionally, the students' exposures were described by a noise immission
level ([L.sub.IM]), i.e., a measure of the cumulative sound (noise) energy to which an individual was exposed over time given by the formula (2):
Other authors, such as , divide the noise and vibration problem into three weakly coupled subproblems (emission, transmission, and immission
) and develop a specific model for each stage.
The main aims of environmental regulation can foster the improvement of emission or immission
