The use of vibration is proposed as a means of controlling the settlement of marine fouling organisms. In this study, panels with embedded lead zirconate titanate, known as PZT, were placed in the field over 3 months. The panels were vibrated at different velocity levels at frequencies between 70 and 445 Hz. It was found that barnacles (Amphibalanus variegatus Darwin and Elminius sp.) were the only fouling organisms affected by the applied vibration, and these organisms settled in significantly lower numbers when the plates were excited at specific frequencies and amplitudes. Panels vibrating at relatively higher frequencies, greater than 260 Hz, exhibited reduced barnacle settlement, whilst lower frequencies in the 70-100 Hz range had little or no effect. The settlement of other fouling organisms such as tubeworms, bryozoans, ascidians and algae did not appear to be affected by the applied excitation. The experimental results showed that increasing the velocity amplitude of vibration was a contributing factor in inhibiting barnacle settlement.
提出利用振动来控制海洋附着生物的沉降。在这项研究中，将嵌入锆钛酸铅（称为 PZT）的面板放置在现场超过 3 个月。这些面板以 70 至 445 Hz 之间的不同速度水平振动。结果发现，藤壶（Amphibalanus variegatus Darwin 和 Elminius sp.）是唯一受到施加振动影响的附着生物，当板在特定频率和幅度下受到激励时，这些生物的附着数量明显减少。以相对较高的频率（大于 260 Hz）振动的面板表现出减少的藤壶附着，而在 70-100 Hz 范围内的较低频率几乎没有或没有影响。其他附着生物，如管状蠕虫、苔藓虫、海鞘和藻类的附着似乎不受施加的激励的影响。实验结果表明，增加振动速度幅度是抑制藤壶附着的一个因素。
