Applications


In the field of transports, the owl flight is one of the most silent amongst birds. This animal eliminates any sound that could alert its prays using several techniques: its extra large wings need less flaps, its paws and wings are covered with very soft down feathers that ansorb any vibration. Lastly, at the end of each wings, saw-tooth feathers break noisy turbulences and reduce noise extensively. Whether it is for train or plane sounds, a research center is dedicated to sound reduction technologies created in Southampton. Covering tests are being undertaken for train and will be tested for the Airbus A380.
