diffracted soundとは 意味・読み方・使い方

The noises N (a diffraction sound) diffracted on the upper end 14A of the soundproof wall 14 and the canceling sound UN (a diffraction sound) diffracted on the upper end 14A of the soundproof wall 14 overlap each other to reduce the noise level on the anti-road side of the soundproof wall 14.例文帳に追加

防音壁１４の上端１４Ａで回折した騒音Ｎ（回折音）と、防音壁１４の上端１４Ａで回折した打消し音ＵＮ（回折音）とが重なり合い、防音壁１４の反道路側での騒音レベルが低減する。 - 特許庁

With this configuration, since the acoustic sound arriving at one of the sound holes for sound collection can be prevented from being diffracted and arriving at the other sound collecting element, acoustic paths (P1, P2) are integrated, and directive sound collection can be executed by appropriate operation processing.例文帳に追加

これにより、一方の収音素子用の音孔に到来した音響が回折して他方の収音素子に到達することがなく、音響パス（Ｐ１，Ｐ２）が一本化され、適切な演算処理によって指向性収音が可能となる。 - 特許庁

To provide a sound source separating device by which the separation of a sound with high accuracy is attained in a short time even in such a case that the sound is diffracted on a casing such as a cellular phone.例文帳に追加

携帯電話などのように筐体上で音が回折するような場合であっても、短時間に高精度な音の分離を実現することができる音源分離装置を提供する。 - 特許庁

To reduce sound leakage to the rear outside a speaker box through the inside of the speaker box, to improve sound absorption performance in the speaker box and to reduce sound diffracted from the front to be leaked to the rear.例文帳に追加

スピーカボックス内を通じてスピーカボックスの外側後方に漏れる音を低減し、スピーカボックス内の吸音性能を改善するとともに、正面から回析して後方に漏れる音も低減する。 - 特許庁

The components corresponding to the disturbing sound diffracted to a microphone from the sound inputted to the microphone 1 are suppressed by a subtracter 3 and an echo canceller 9.例文帳に追加

マイクロホン１で入力された音声から、マイクロホン１へと回り込んだ妨害音に相当する成分を減算器３およびエコーキャンセラ９により抑圧する。 - 特許庁

To alter amplitude/phase characteristics of a diffracted sound itself of a noise source by changing a sound proof barrier itself with an active silencing device into a cylindrical or rectangular duct etc., and to uniformly and securely reduce the diffracted sound of the sound proof barrier circumferentially along the barrier with one pair of a controller and a microphone even when a plurality of speakers are used.例文帳に追加

能動消音装置付き遮音壁において、遮音壁自体を円筒状や矩形等のダクトに変えて騒音源の回折音自体の振幅・位相特性を改変し、スピーカは複数用いても、制御装置、マイクが１組で遮音壁の回折音を壁周方向に均一に確実に低減できるようにする。 - 特許庁

Sound transmitted from outside of the room into the room through the film 3 is reflected from the sound reflecting plate 21 of the sound insulating plate 20 and then diffracted via sides of the interval d, defined between the sound reflecting plate 21 and the wall 1, to behind the reflecting plate 21, to reach a human listener.例文帳に追加

居室外から膜３を透過した透過音は音響遮蔽板２０の音響反射板２１で反射し、その反射音は音響反射板２１と壁１の間隔ｄの側方から音響反射板２１の後方へ回折し、受聴者まで伝搬する。 - 特許庁

The reduced sound is secondarily diffracted by the side 17a of a diffraction plate 17 and propagated to the side of the soundproofing wall 12 opposite to the noise source 16.例文帳に追加

低減させられた音は、さらに回折板１７の辺１７ａで２次回折して、防音壁１２の騒音源１６と反対側に伝搬する。 - 特許庁
