The flow induced oscillation in a cavity exposed to external high speed flow and its suppression by means of soundexcitation at the leading edge of the cavity are experimentally studied.
Studies of the sound radiation and vibration of the ring stiffened cylindrical shell under the circumferential excitation are important to predict the noise of the underwater naval craft.
周向激励下加筋圆柱壳体振动和声辐射特性的研究是预测水下航行器壳体噪声的关键环节。

With forceful, clear, and smooth reverberated sound as well as special harmonic excitation functions, the noise frequency domain is obviously reduced, thus playing vocal perfectly and easy.
