What is noise canceling?

The headphones equipped with the noise canceling function detect ambient noise using the built-in microphone and output antiphase sound to reduce the noise. This reduces unwanted ambient noise, especially in a vehicle such as an airplane, train or bus, allowing you to enjoy music even at a low volume.

Waveform of noise (original sound) ()

The microphone built into the headphones picks up ambient noise, then the noise canceling circuit analyzes the signal of the noise.

Waveform of antiphase sound ()

Antiphase sound that cancels out the analyzed noise is generated.

Waveform of composed and canceled noise ()

The original and antiphase sound combine to cancel out the original sound, reducing noise at the eardrums.
