Innovative Noise-Cancelling Windows Block Noise While Allowing Ventilation
摘要
Noise control has always been a hot topic in Taiwan. The EPA has not only been strengthening control of noise pollution sources through government regulations, but also continues to develop new control technologies. After considering innovative concepts of active noise control technology that have been used in other countries, the EPA recently installed the first set of noise-cancelling windows for demonstration in Taiwan. Initial studies have shown that these windows can reduce noise by about 3 decibels while still allowing for proper indoor ventilation.

Active Noise Control (ANC) is a method that reduces noise by using a computer to analyze the perceived noise sources and generating an inverted wave to cancel the noise out. The market has already been filled with products utilizing ANC technology, including active noise-canceling earphones, and noisecanceling systems in confined spaces such as cars and airplanes. Installing noise-canceling windows for noise control in public places came as an outcome of initial studies and new concepts from the EPA’s technology program during 2019. Since noise-canceling windows are not yet commercialized and are still at the early stage of development both in Taiwan and overseas, the EPA will continue to do research on the practical applications of ANC systems and related details such as suitable space sizes.
