24、Technical Committee ISO/TC 43 “Acoustics” in DIN EN ISO 17201-3:2010-06 EN ISO 17201-3:2010 (E) 3 Introduction The initiative to prepare a standard on impulse noise from shooting ranges was taken by the Association of European Manufacturers of Sporting Ammunition (AFEMS), in April 1996 by the submis

25、sion of a formal proposal to CEN (see doc. CEN N 1085). After consultation in CEN in 1998, CEN/TC 211, Acoustics, asked ISO/TC 43, Acoustics, Subcommittee SC 1, Noise to prepare ISO 17201 (all parts). This part of ISO 17201 provides guidance for sound propagation calculation of shooting sound from s

26、hooting ranges. If calculation procedures are not implied or specified by local or national guidelines, rules and regulations, and if a more sophisticated propagation model is not available, then ISO 9613-2 may be applied, provided that the recommendations in this part of ISO 17201 are observed. The

27、 source energy of muzzle blast is typically measured or calculated for free-field conditions and often exhibits strong directivity. In many cases firearms are fired within a shooting range which has structures such as firing sheds, walls or safety barriers. Guns, particularly shotguns, are sometimes

28、 fired in many directions, e.g. in trap and skeet where the shooting direction is dictated by the flight path of the clay target. This part of ISO 17201 recommends ways in which source data can be adapted for use with ISO 9613-2 to obtain a general survey for the sound exposure levels to be expected

29、 in the neighbourhood of shooting ranges. DIN EN ISO 17201-3:2010-06 EN ISO 17201-3:2010 (E) 4 1 Scope This part of ISO 17201 specifies methods of predicting sound exposure levels of shooting sound for a single shot at a given reception point. Guidelines are given to calculate other acoustic indices

30、 from the sound exposure level. The prediction is based on the angular source energy distribution of the muzzle blast as defined in ISO 17201-1 or calculated using values from ISO 17201-2. This part of ISO 17201 applies to weapons with calibres of less than 20 mm or explosive charges of less than 50

31、 g TNT equivalent, at distances where peak pressures, including the contribution from projectile sound, are less than 1 kPa (154 dB). NOTE National or other regulations, which could be more stringent, can apply. 2 Normative references The following referenced documents are indispensable for the appl

44、e projectile hitting the target 3.13 diffraction point point on top of a barrier which provides the shortest pathlength for the sound travelling over the barrier to the reception point 4 Source modelling 4.1 Introduction The basic quantities to be used are the angular source energy distribution, Sq(

45、), and the angular source energy distribution level, Lq(), as defined in ISO 17201-1. The angle between the line of fire and the line from the muzzle to the reception point is designated by . If the gun is fired in an open air situation, Sq() can be used to describe the muzzle blast. For rifle shots

46、, projectile sound has to be included (see 4.3). Substitute sources can be used for shed situations and for the incorporation of reflection and diffraction to calculate the reception levels as if it was an open field situation. Impact sound caused by the projectile hitting the target can usually be

47、neglected. This part of ISO 17201 does not apply to projectiles containing a charge which is detonated at the target. 4.2 Muzzle blast 4.2.1 Background For the non-free-field situation (such as a shed with one opening), the propagation model of ISO 9613-2 is insufficient, and more complex propagatio

48、n models and calculation procedures are needed. Annex A provides a benchmark case and a demonstration of how sophisticated sound propagation approximations (see Annex B) may be used to describe the sound emitted from such a range, based on the free-field data of the angular source energy distributio

49、n levels. The sound emission is then expressed by the angular source energy level distribution of a substitute source positioned at a representative position in front of or above the firing shed. All further calculations of the sound pressure level are carried out as specified in Clause 5 by a point source with directivity independent of the range, which may be formed by a shed, baffles and side walls, etc. 4.2.2 Open field situation If the weapon under consideration is used outsid
