“Sound is a pressure wave, which consists of a compression phase and a rarefaction phase. A noise-cancellation speaker emits a sound wave with the same amplitude but with inverted phase (also known as antiphase) to the original sound.”

“The waves combine to form a new wave, in a process called interference , and effectively cancel each other out – an effect which is called phase cancellation .”

Based on the Acoustic Stirling Technology .
