Active noise cancellation started off in over-ear and on-ear headphones, and can now be found in earphones, in both wired or wireless varieties. As the first word of the term suggests, active noise cancellation requires power, as opposed to passive noise reduction. The battery power feeds ANC circuitry that, using microphone signal feeds, creates a live, inverse signal of the surrounding noise. Just as a negative number added to its positive equivalent equals zero, the goal here is to offset the actual surrounding noise with inverse sound waves.
