Our activities in the project
In addition to leading the consortium, the main tasks of the research group are the development of acoustic sensor technology and AI-based analysis algorithms. Part of the acoustic sensor technology consists of a calibrated sound level meter with a class 1 single measurement microphone, which allows the level and spectrum of sound events to be measured and documented in a court of law. A microphone array is developed for the clear localisation of sound events, which serves to spatially filter the sound field. Microphone arrays have a variably adjustable directional characteristic and are capable of suppressing interference signals from other directions and visualising sound fields ("acoustic camera").

Project details
The number of motorbike and tuning enthusiasts has risen sharply in recent years. Illegal street races regularly take place in the larger cities, which are extremely dangerous for other road users on the one hand and very disturbing due to the noise generated on the other. Various modifications to the engine and exhaust system produce extremely loud bangs that can be heard from afar and are an enormous nuisance for neighbouring residents. The aim of the project is to develop a multi-sensor measuring device that will enable the police to secure forensic evidence in the course of tuning events. This mobile measuring device will consist of a combination of acoustic sensors, visual and thermal sensors and a distance sensor.
