Main Research Topics

For many years, Fraunhofer IDMT has been conducting research and development in the fields of audio-visual signal processing and analysis, machine learning and the associated data protection and security aspects. Currently, the researchers investigate to what extent these established analysis methods from the broadcasting sector can be adapted and applied to industrial applications.

At regular intervals, the scientists exchange information with industry representatives and present current research results at scientific conventions.

Forschung im Dialog

Wissen, warum es wo laut wird

»Stadtlärm« – Ein Forschungsprojekt zur Klassifizierung und Vorhersage von städtischem Lärm

 

Dokumentation MDR Wissen / 17.1.2020

Ist es zu laut bei uns?

Die 45 minütige Dokumentation untersucht gemeinsam mit dem Fraunhofer IDMT und weiteren Experten Lärmursachen und fragt, wie man Lärm vermeidet.
