Foreword
ISO (the International Organization 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 established 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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
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 rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).

This second edition cancels and replaces the first edition (ISO 17201-3:2010), of which it constitutes a
minor revision. The changes compared to the previous edition are as follows:
— Formulae (B.1) and (B.3) have been corrected by insertion of F .
— Minor corrections have been made in Annex C.

ISO 17201-3:2019(E)
Introduction
The initiative to prepare a standard on impulse noise from shooting ranges was taken by AFEMS, the
Association of European Manufacturers of Sporting Ammunition, in April 1996 by the submission of
a formal proposal to CEN. 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 document 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 is not available, then ISO 9613-2 may be
applied, provided that the recommendations in this document 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 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 document recommends ways in which source data can be adapted for
use with ISO 9613-2 to obtain a general survey for the sound exposure leve
