Passive Noise Control
Passive noise control refers to the use of materials and structures to reduce noise levels without the use of active noise control systems. This can include the use of sound-absorbing materials, vibration damping materials, and structural modifications to reduce noise transmission. Passive noise control is often used in aerospace engineering to reduce noise levels in aircraft and spacecraft, as well as in the design of launch vehicles and satellites. The use of passive noise control can help to improve the comfort of passengers and crew, as well as reduce the impact of noise pollution on the environment.
