Description / Abstract:

SCOPE AND FIELD OF APPLICATION

This International Standard establishes the terminology for describing the physical properties of sonic booms caused by overflight of supersonic aircraft, and specifies the minimum performance requirements of equipment and the method to be used for their measurement. The conditions of measurement envisaged include those in which the direction and time of arrival of the pressure disturbance and even i t s approximate intensity are not necessarily known in advance. This International Standard provides the basis for the measurement and description of sonic boom pressure signatures suitable for evaluating their effects on people, structures, animals and unstable terrain features.

NOTE - The physical properties described by these procedures are properties of particular acoustic events (sonic booms) occurring at a specified location. They cannot be considered as properties of a particular aircraft, since the measured quantities depend also on prevailing conditions of flight, of atmosphere and of ground.
