During the presentation, the Chairman of the jury and DLR Executive Board member rolf Henke (2nd from right) measures the noise level of a propulsion system recorded by the students at original volume. One of the demanding requirements of this year's NASA/DLR Design Challenge was that the designs should produce low noise emissions.
