This document specifies methods for recording the time history of the sound pressure produced either by shooting with calibres of less than 20 mm, or by detonation of explosive charges of less than 50 g TNT equivalent, within the shooting range at locations of interest, regarding the exposure to sound of the shooter, or any other person within the shooting range. The time history of the sound pressure can be the basis for further analyses of this type of sound at the locations of interest.

What is ISO 8253-3 - Speech audiometric test methods about? ISO 8253-3 is an international organisation for standardization that specifies basic methods for speech recognition tests for audiological applications. To ensure minimum requirements of precision and comparability between different test procedures including speech recognition tests in different languages, ISO 8253-3 specifies requirements for the composition, validation, and evaluation of speech test materials, and the realization of speech recognition tests. ISO 8253-3 does not specify the contents of the speech...
Acoustics. Audiometric test methods. Speech audiometry
This document specifies basic methods for speech recognition tests for audiological applications. NOTE Examples of speech materials are given in Annex A. In order to ensure minimum requirements of precision and comparability between different test procedures including speech recognition tests in different languages, this document specifies requirements for the composition, validation and evaluation of speech test materials, and the realization of speech recognition tests. This document does not specify the contents of the speech material because of the variety of languages. Furthermore, this document also specifies the determination of reference values and requirements for the realization and manner of presentation. In addition, there are features of speech tests described which are important to be specified, but which are not understood as a requirement. This document specifies procedures and requirements for speech audiometry with the recorded test material being presented by an audiometer through a transducer, e.g., an earphone, bone vibrator, or loudspeaker arrangement for sound field audiometry. Methods for using noise either for masking the non-test ear or as a competing sound are described. Some test subjects, for example children, can require modified test procedures not specified in this document. Specialized tests, such as those used for evaluating directional hearing and dichotic hearing, are outside the scope of this document.
