Patent ID: 8340308

Claim:
An automatic noise compensation method used with audio reproduction equipment, which used a first time period and a second time period comprising: (a) collecting a plurality of mixed audio signals, each mixed audio signal including equipment sound output by the audio reproduction equipment, and background noise; (b) removing the equipment sound from the mixed audio signals to obtain the background noise therein; (c) determining whether or not the plurality of mixed audio signals under inspection include a significant sound, and if the determination is affirmative, proceeding to (d); (d) when the energy of the background noise in the mixed audio signals under inspection is smaller than the energy of the significant sound, adjusting the volume of the audio reproduction equipment according to the energy of the significant sound and the background noise in the mixed audio signals under inspection to satisfy a first compensation condition, wherein, in (d), after automatically adjusting the volume of the equipment sound output by the audio reproduction equipment, performing (d) is suspended for the second time period so as to maintain the stability of the volume following adjustment; and if the determination is negative, proceeding to (e);(e) adjusting the volume of the audio reproduction equipment according to the energy of the background noise in the mixed audio signals under inspection to satisfy a second compensation condition.
