Målinger av lydtrykket i nærfeltet til en rifle

This report is part of an ongoing effort to improve the ability of the Norwegian Defense Estate Agency (FB) to assess noise pollution from ring ranges. Here we provide documentation of measurements done at Norwegian Defense Research Establishment (FFI) 16 September 2005, to capture time series of the sound pressure near a ri e. This report is the rst one in a series, to provide data for different types of weapons under different conditions. At the FFI we are currently developing methods to theoretically predict the sound pressure near the muzzle of a weapon. The measurements reported here will later be used to check the validity of the theoretical methods against measured values.
