These ‘bits’ which represent the sound are then analysed and manipulated by a course of action named Electronic Signal Processing. Software is then accustomed to execute precise variations on the `bits` of knowledge such as reducing the amplification of background sound. These electrical bits of information are then fed into a minute microphone and transformed back into sound, which can be fed in to the ear channel to act over the eardrum.
