摘要
本文介绍一种用于腔体内中低频噪声控制的多模态声共振器,即长T型声共振器。包括长T型共振器的设计方法、控制机理和控制效果等。同时对该共振器在船舶噪声控制上的应用进行了初步探讨。
A multi-modal acoustic resonator, long T-shaped acoustic resonator used for noise control in the low and middle frequency range, is introduced, including its design methodology, control mechanism, and control effectiveness. Successful preliminary study of ship noise control by using T-shaped acoustic resonators is also demonstrated.
