Tightness Integrity - Wind Noise & Water Leaks.
Quality control applications were developed for the transportation sector to improve the tightness of vehicles. The method consists of flooding the interior of a volume with ultrasound waves. Due to their very small wavelenght these can penetrate tiny holes. Using an SDT detector on the outside of the volume, inspectors can quickly pinpoint the source of defects that could become potential sites of water leaks or wind noise. Current sector uses:

Automobile - Wind and Water Leaks on Cars
Aeronautics - Integrity of Aircraft and Helicopters
Transportation - Trucks, Buses, Trains
Buildings - Integrity of Building Envelopes
Military - Submarines, Aircraft, Space Vehicles
Nuclear - Containment Wall Integrity
Marine Industry (Click "Hatch covers ultrasonic tightness testing and on board condition monitoring").
