<p>Disclosed is an equalization apparatus and method based on audiogram. The equalization method includes the steps of a) outputting a reference sound having reference frequency and intensity for approximate assumption of auditory threshold, b) determining a start sound corresponding to an assumed value of the auditory threshold while calling a sound having intensity different from a prior sound at a sound source memory depending on whether a user has received an answering signal in response to the reference sound, c) outputting a first test sound whose intensity is controlled at a value set prior to the start sound, having the reference frequency, d) calling a test sound having intensity and frequency different from the prior sound at the sound source memory depending on whether the user has received the answering signal, e) storing data on reception of the answering signal of the user in response to the test sound, f) repeating the steps d) to e), g) determining the auditory threshold per previously set frequency band using the reception data of the answering signal, and h) performing equalization depending on the auditory threshold per the determined frequency.</p> |
