After the cancellation of DAGA 2020, DAGA 2021 will take place in Vienna from August 15 - 18, 2021. Fraunhofer IDMT will present latest research results in the fields of "Acoustic Metamaterials" and "MEMS Loudspeakers" in two structured sessions.
Structured Session: Acoustic Metamaterials
Organization and Chair: Prof. Dr.-Ing. Joachim Bös, M.S./SUNY – Director Fraunhofer IDMT, Head of DEGA technical committee "Physical Acoustics", Elke Deckers
Metamaterials – a field of research that has its origins primarily in optics and electrical engineering – have also been attracting growing interest in acoustics for some years now. Basically, these are artificially produced materials whose properties differ from those of natural materials, such as negative stiffness or a negative refractive index. As such, they enable novel approaches to solving existing technological challenges. The structured session "Acoustic Metamaterials" will include contributions on recent results from industry and research. Not only will various application areas be addressed, but the actual design process of acoustic metamaterials will also be examined in more detail.
Structured Session: MEMS loudspeaker – where are we today?
Organization and Chair: Dr.-Ing. Daniel Beer – Head of Electroacoustics Fraunhofer IDMT, Head of DEGA technical committee "Electro-Acoustics"
After the MEMS loudspeaker was mainly just a research topic in the last years, the transition into the product area is now taking place. The contributions include recent results from industry and research.
In addition, the division Hearing, Speech, and Audio Technology in Oldenburg will present their research areas of auditory modeling, speech enhancement, and sound personalization in several contributions:
