Cabin Noise – Prediction, Testing, Reduction

The 27th CEAS-ASC Workshop on Cabin Noise will be jointly hosted by SFB/TRR SynTrac and DLR. Registration and participant information will be available soon. 
The workshop includes a workshop dinner in the evening of Oct. 20. Optionally, a lab tour to DLR’s acoustic windtunnels and possibly the turbofan test stand at TU Braunschweig will be offered after the end of the workshop in the afternoon of Oct. 21.

Workshop Topics

Cabin noise in aircraft and ground vehicles is not only a topic in passenger comfort, but it concerns health, working environment for operating personnel, and -not the least- a low noise cabin is a quality criterion for customers and thus economic success for manufacturers. Cabin noise is as well a topic in space applications, as particularly the launch noise may be harmful for some of the payload. Cabin noise is complex since it occurs as a result of many different sources of sound. A substantial complication is the coupling of aerodynamics, aeroacoustics, vibroacoustics along the transfer path from source to the cabin interior air. The workshop focusses explicitly on cabin noise occurring directly or indirect as a result of flow (Aeroacoustics). Topics of interest include:

•    airborne noise from the propulsion and turbulent flow past the surfaces
•    structure borne noise, i.e. by the excitation of vibrations from rotors and jets
•    interior sources from within the vehicle such as the HVAC system as well as hydraulic pumps etc.
•    noise from electric motors in new a/c concepts with electrically driven propulsion etc.
•    tone noise excitation from open rotors/ propellers as the most energy efficient propulsion for flight
•    payload compartment in space applications

The Workshop intends to bring together experts to discuss possibilities for prediction and testing in the light of today’s capabilities for computation and experiments. Moreover, concepts for passive and active reduction of cabin noise in view of intelligent materials and systems are of high interest. Contributions from the field of psychoacoustics are highly welcome as well.
