Active noise control ANC , also known as noise cancellation , or active noise reduction ANR , is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. Sound is a pressure wave , which consists of alternating periods of compression and rarefaction. 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 destructive interference. Modern active noise control is generally achieved through the use of analog circuits or digital signal processing.

Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals. Audio signals are electronic representations of sound waves — longitudinal waves which travel through air, consisting of compressions and rarefactions. The energy contained in audio signals is typically measured in decibels. As audio signals may be represented in either digital or analog format, processing may occur in either domain. Analog processors operate directly on the electrical signal, while digital processors operate mathematically on its digital representation.
