This Nordtest method specifies a method for measurement of A-weighted sound pressure levels (noise immission) from railway traffic inside and outside buildings and in open terrain.
The method includes manually operated measurements only (and not long term automatic measurements). In Annex A a few guidelines are given for the performance of measurements under weather conditions other than those described in the main body of this Nordtest method.
