Fraunhofer-Institut für Digitale Medientechnologie IDMT

Individual company presentation

The Fraunhofer Institute for Digital Media Technology IDMT, headquartered in Ilmenau (Thuringia), is one of 76 institutes and research units of the Fraunhofer-Gesellschaft. The Fraunhofer-Gesellschaft is the world's leading organization for applied research. The institute offers companies research collaboration and development services through to prototype production.

The Fraunhofer IDMT develops innovative technologies for the targeted generation and control of sound. This is used, for example, in the production and reproduction of spatial sound experiences for the professional audio, entertainment and automotive sections. The institute is also working on processes for the active improvement and targeted generation of sound fields. A new field of application will be demonstrated at Intersolar Europe - the acoustic cleaning of photovoltaic modules using structure-borne sound. Here, sound fields are used in a targeted manner to cause solar modules to vibrate and thus remove soiling such as dust and sand from large and difficult-to-access solar systems.

You can read more about this here.

In addition to the development of actuator solutions, another focus of the institute is the secure and efficient AI-based recognition and classification of audio and video data. Our solutions are used, for example, in industrial sound monitoring, media forensic analysis, music classification and recommendation, broadcasting and media applications as well as environmental and biodiversity monitoring. An important aspect in the collection, evaluation, storage and transmission of data is the trustworthy handling of this information. To this end, the institute develops the necessary tools to ensure the protection of sensitive company and machine data as well as personal data.

The pictures show the step-by-step cleaning of a photovoltaik module using structure-borne sound. The soiling is gradually removed by targeted acoustic activation of the panel and the associated vibrations.
