摘要

PURPOSE: A private hearing property and the sound sizing method considering the speaker transfer characteristic and the loudness control device using the same are that the clear sound hitting for the private hearing property the gradually controlled sound is reflected to the speaker transfer characteristic it gives an order is formed in the private hearing property. CONSTITUTION: A threshold of hearing system sound is instituted as the first standards sound of the acoustic-apparatus or the communications device(S10). The fixed first standards sound as described above is compared with the lowest price blue color sound of individual(S20). The lowest price blue color sound of individual is measured at(S30). The lowest price blue color sound of the identified individual as described above pitches as the second standards sound of individual(S40).
