Zen Acoustics develops active noise cancellation technology designed specifically to mitigate noise pollution through open windows. The company’s proprietary system utilizes window-mounted hardware that detects incoming acoustic waves, such as traffic or transit noise, and instantly generates opposing anti-noise frequencies to neutralize the sound. This approach allows residential and commercial properties to maintain natural ventilation and airflow without compromising the indoor acoustic environment. By reducing external noise levels by over 80%, the technology addresses the challenge of balancing indoor air quality with noise control in dense urban areas.
