• Acoustic and Sonar Training Seminars - Applied Technology Institute (ATI) is the leading technical training organization specializing in short courses in acoustics, signal processing and underwater sound.
• Acoustical detection of enemy aircrafts - From the first world war until the 30's air acoustics played an important role in the air defence. Air vehicles carrying a weapon could not be located from the ground e.g. at night time or under cloudy conditions. As radar was still to be discovered, vision had to be supplemented by hearing using the sound of the engines. (MUSEUM "WAALSDORP": TNO-FEL Museum).
