sound reduction factorとは 意味・読み方・使い方

This device adds a correlation reduction signal for reducing the correlation of the sound generated by the factor other than the combustion of a burner to a sound signal, when acquiring the sound within a combustion furnace 41 as a sound signal from plural systems of voice detectors 1 and 1 forming a pair to a burner and detecting the combustion state of the burner, based on the correlative value of these sound signals.例文帳に追加

バーナに対して対をなす複数系統の音声検出部１・１から燃焼炉４１内の音声を音声信号として獲得し、これら音声信号の相関値に基づいてバーナの燃焼状況を検知する際に、バーナの燃焼以外の要因により発生した音声の相関を減少させる相関低減信号を音声信号に付加する。 - 特許庁

To provide a constitution which is simple and capable of open loop, by attaining improvement in power factor and reduction of a higher harmonic current and also reducing generation of noise and heat and reducing a reactor sound also providing no current protecting circuit, in a rectifying circuit.例文帳に追加

整流回路において、力率の向上および高調波電流の低減を図るとともに、ノイズおよび熱の発生を低減し、また、リアクトル音を低減するとともに、電流保護回路を設けずに簡易的でかつオープンループ可能な構成とすること。 - 特許庁
