aural characteristicとは 意味・読み方・使い方

A frequency band division means 6 divides the normalized residual signal obtained by a power normalization means 5 into plural partial frequency bands with a frequency resolution corresponding to the aural sensitivity characteristic which is aural characteristic of human being.例文帳に追加

帯域分割手段６はパワー正規化手段５で得られた正規化残差信号を、人間の聴覚的な性質である聴覚感度特性に対応した周波数分解能で複数の部分帯域に分割する。 - 特許庁
