ISO/FDIS 17201-4 is a document in the final stage of development as a standard for noise from shooting ranges. Specifically, it focuses on the calculation of projectile sound, providing a model to determine the acoustical source level and its spectrum. This final draft international standard (FDIS) is awaiting final approval by member countries, which will then lead to its official publication as an ISO standard.
