Technical visits

RWTH Aachen University - aixCAVE Virtual Reality System & Institute of Technical Acoustics

Date: Wednesday, 3:45-6 pm
70 persons max.
Registration: At the conference (registration office)


The visit to the Institute of Technical Acoustics of RWTH Aachen University provides an insight into the scientific activities and the infrastructure of the research institute. The tour will cover the two main aspects of virtual acoustics and hearing research. Members of the institute will show one of the largest virtual reality systems worldwide, the sound reproduction of room acoustic scenarios calculated in real-time and the auralization of building environments including sound insulation. In the field of hearing research, experimental setups will be shown to investigate auditory attention switching, speech in noise perception with hearing aids and children’s hearing in a mobile laboratory facility for listening experiments using virtual acoustics.

Participants can identify two topics of core interest in order to experience those two exhibits in a dedicated demonstration.
The topics to choose from are the

  • aixCAVE VR System,
  • building acoustics auralization in a HMD demonstration
  • Speech in noise perception in a spatial scenario with hearing aids in a hearing booth
  • Binaural auditory selective attention experiment in a hearing booth
  • Speech reception of children using virtual acoustics in a mobile hearing lab (MobiLab)

Please indicate your topics of interest when registering to the technical visit at the registration desk on-site. Participation in this live demonstration is subject to availability.


RWTH Aachen University - Institute for Automotive Engineering

Date: Tuesday, 9h00 - 10h00
30 persons max.
Registration: At the conference (registration office)

On this tour, the participants are invited to the labs of the Institute for Automotive Engineering (ika) of the RWTH Aachen University. The increasing importance of electromobility and autonomous driving pose new challenges for acoustic research in the automotive sector. Participants will have the opportunity to experience various test benches including a combined thermal-acoustic chamber and the fully electric research vehicle SpeedE, which incorporates a variety of interesting concepts such as customizable Active Sound Design and a steer by wire system for steering angles up to 90°.


Sound. Voice. Passion. – Experience HEAD acoustics

Date: Wednesday, 15h15-18h00
Duration: 1 1/2 - 2 hours

24 persons max.
Registration: At the conference (registration office)

In addition to a company tour (including insights into our test and research facilities), you are invited to become active yourself. Look forward to suspense topics: From active sound design through sound intensity measurements to procedures for optimizing voice and audio quality. Furthermore, we present 5-minute teaser lectures on current research and provide the opportunity to interact with our software and hardware solutions. This excursion will bring you closer to the variety of HEAD acoustics
