Abstract:
The present invention provides a method of eliminating background noise and a device using the same. The method of eliminating background noise comprises the steps of: detecting an effective value of a received audio signal, and generating an average power signal of the received audio signal; generating a noise eliminating control signal by comparing the average power signal with a first threshold; and eliminating the noise, and amplifying the voice signal using the noise eliminating control signal. A device of eliminating background noise comprises a detecting unit, which is configured to detect an effective value, and generate an average power signal of the received audio signal; a first signal generating unit, which is configured to generate a noise eliminating control signal; and an amplifying unit, which is configured to eliminate the noise, and amplify the voice signal.
