Passive Noise Control

Passive Noise Control involves using physical materials and structures to reduce sound transmission without active devices. It works by blocking, absorbing, or reflecting sound waves—such as adding insulation, soundproof panels, or double-glazed windows—to minimize noise in a space. This approach relies on the properties of materials to dampen sound energy, making environments quieter and more comfortable. It's commonly used in building design, automotive, and industrial settings to enhance acoustic comfort without requiring power or active systems.
