Abstract

본 발명은 음향기기에 관한 것으로, 특히 무음 구간에 자동으로 뮤팅 기능을 수행하여 신호대 잡음비(S/N비)를 개선하도록 한 음향기기의 무음 구간 뮤팅방법에 관한 것이다.The present invention relates to an acoustic device, and more particularly, to a silent section muting method of an acoustic device to automatically perform a muting function in a silent section to improve a signal-to-noise ratio (S / N ratio).

이러한 본 발명은 음성 출력 레벨을 일정 시간 검출하여 그 평균치를 산출하는 제1과정과, 산출한 평균치와 무음 구간을 판별하기 위해 기설정된 기준 레벨과를 비교하는 제2과정과, 비교결과 설정된 기준 레벨이 평균치보다 클 경우 무음 구간으로 판단하고 뮤팅을 위한 제어신호를 발생시키는 제3과정을 순차 실행시켜 신호대 잡음비를 개선시키게 되는 것이다.The present invention includes a first process of detecting a voice output level for a predetermined time and calculating an average thereof, a second process of comparing the calculated average value with a preset reference level to determine a silent section, and a reference level set as a result of the comparison. If it is larger than this average value, it is determined that it is a silent section, and the signal-to-noise ratio is improved by sequentially executing a third process of generating a control signal for muting.

Claims (1)

음성 출력 레벨을 일정 시간 검출하여 그 평균치를 산출하는 제1과정과, 상기 산출한 평균치와 무음 구간을 판별하기 위해 기설정된 기준 레벨과를 비교하는 제2과정과, 상기 비교결과 설정된 기준 레벨이 산출한 평균치 보다 클 경우 무음 구간으로 판단하고 뮤팅을 위한 제어신호를 발생시키는 제3과정으로 이루어짐을 특징으로 하는 음향기기의 무음 구간 뮤팅방법.A first process of detecting a voice output level for a predetermined time and calculating an average thereof, a second process of comparing the calculated average value with a preset reference level to determine a silent section, and calculating the reference level set as a result of the comparison If the average value is greater than the silent section muting method characterized in that it consists of a third process for generating a control signal for muting. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
