17、zation for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establishe

18、d has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

19、International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Pub

20、lication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent

23、ting ranges was taken by the Association of European Manufacturers of Sporting Ammunition (AFEMS), in April 1996 by the submission 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 prep

24、are ISO 17201 (all parts). This part of ISO 17201 provides guidance for sound propagation calculation of shooting sound from shooting ranges. If calculation procedures are not implied or specified by local or national guidelines, rules and regulations, and if a more sophisticated propagation model i

25、s not available, then ISO 9613-2 may be applied, provided that the recommendations in this part of ISO 17201 are observed. The 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

26、shooting range which has structures such as firing sheds, walls or safety barriers. Guns, particularly shotguns, are sometimes 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 wh

27、ich source data can be adapted for use with ISO 9613-2 to obtain a general survey for the sound exposure levels to be expected in the neighbourhood of shooting ranges.

28、 from shooting ranges Part 3: Guidelines for sound propagation calculations 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 from the sound exp

29、osure 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 g TNT equivalent,

30、at distances where peak pressures, including the contribution from projectile sound, are less than 1 kPa (154 dB).

44、y distribution, Sq(), 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 bla

45、st. For rifle shots, 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 tar

46、get can usually be 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

47、 complex propagation 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

48、 energy distribution 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

49、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 outside a firing shed or similar structure, use the angular source energy distribution level Lq() of the specific weapon/ammunition combination directly. If a shot is fired with a reflecting surface near the shooter, take the reflection into account. The directivity has to be adjusted accordingly. If th
