10 Revolutionary Stealth Technologies in Modern Naval Vessels
3. Acoustic Signature Management

Sophisticated acoustic signature control systems used in modern navy ships help to reduce underwater detection. This technology includes active noise canceling devices, specifically engineered propulsion systems, and several layers of sound-dampening materials. While prairie-masker air systems leak small bubbles around the hull and propellers to mask propulsion noise, advanced rubber mounting systems isolate equipment vibrations. Virtual silence to passive sonar systems is achieved by computer-controlled active noise cancelling devices continuously monitoring and countering sound characteristics in real-time. Combining these technologies has cut submarine detection ranges by more than 75% from past generations.
