Emisjonsdata for støy fra HK 416 og HK 417

In Norway noise from military installations must not exceed limits set in law. Norwegian Defence Estates Agency is responsible for planing installations to accomplish this. One tool is to be able to calculate noise maps around installations. Such maps are made with the software package Milstøy. As input Milstøy use noise emission data close to the weapon, 10 m for rifles. New emission data must be acquired continuously as new weapons are purchased. This report gives emission data for HK 416, HK 416 K and HK 417 which has recently been purchased by the Norwegian Defence. These data replaces the temporary emission data previously given in FFI-report 2008/02125 We see that the noise level from HK 417 is comparable to AG3. The noise level from HK 416 is 2.8 dB lower than AG3.
