Abstract

A noise cancelling apparatus is disclosed. In accordance with the apparatus, a noise cancellation signal is generated such that a residual noise signal is maintained to be below a minimum audible acoustic pressure level to reduce a noise, and an external noise is cancelled to hear only a desired audio signal when using a portable device using an earphone or a headphone.
