n.御寒耳罩

The optimum design of the controller of compound active noise cancellation earmuff is discussed. 探討了復(fù)合式有源消聲耳罩的控制器的優(yōu)化設(shè)計(jì)方法。

This research proposed several rib-strengthened structures trying to improve the sound insulation of an earmuff by increasing its stiffness. 本研究提出了數(shù)種肋條強(qiáng)化結(jié)構(gòu)，提升耳罩的剛性以改善隔音效果。
