Active Noise Cancellation for Buildings

Active noise cancellation for buildings uses window-mounted systems that generate anti-noise sound waves to cancel out incoming outdoor noise before it penetrates indoor spaces. Unlike traditional soundproofing that blocks noise through mass and insulation, ANC systems use microphones to detect incoming noise, then produce inverse sound waves that destructively interfere with the unwanted sound.

The technology is particularly effective against low-frequency noise from traffic, aircraft, construction, and industrial sources that traditional windows struggle to block. Window-mounted units contain microphone arrays, signal processing electronics, and speaker arrays that work together to create quiet zones inside buildings. Advanced systems can adapt to changing noise patterns in real-time and maintain effectiveness across different frequencies. This enables urban residents to enjoy quiet indoor environments without the cost and complexity of complete building soundproofing renovations.
