In-situ Prediction of the Acoustic Impact of Stun Grenades

This work presents a tool for the prediction of the acoustical impact of stun grenades for use during an ongoing operation. The aim is to provide in-situ special forces with the necessary resources to better fulfill the principle of proportionality in the use of stun grenades. To this aim, a standardized measuring procedure was developed to measure the acoustic parameters of stun grenades. In a data acquisition phase, the impacts of different types of stun grenades used by Austrian special forces were recorded and evaluated. In the next step, a mathematical model for the simulation of the sound pressure level caused by stun grenades within rooms was investigated. This model considers parameters for the sound pressure level such as the volume of the room, the equipment in the room, the type of grenade and their distance to a human being. To enable a realistic evaluation scenario, an Android-based demonstrator application with a graphical user interface was developed.
