In this study various species of captive marine fish and one species of squid were exposed to the noise from a single air gun. Six trials were conducted off the coast of Western Australia with each trial using a different noise exposure regime. Noise levels received by the animals ranged between 120 and 184 dB re 1 μPa(2).s (SEL). Behavioural observations of the fish and squid were made before, during and after air gun noise exposure. Results indicate that as air gun noise levels increase, fish respond by moving to the bottom of the water column and swimming faster in more tightly cohesive groups. Significant increases in alarm responses were observed in fish and squid to air gun noise exceeding 147-151 dB re 1 μPa SEL. An increase in the occurrence of alarm responses was also observed as noise level increased.
在这项研究中，各种海洋鱼类和一种鱿鱼被暴露在单个空气枪的噪声中。在西澳大利亚海岸进行了六次试验，每次试验使用不同的噪声暴露方案。动物接收到的噪声水平在 120 到 184 dB re 1 μPa(2).s（SEL）之间。在空气枪噪声暴露前后，对鱼类和鱿鱼进行了行为观察。结果表明，随着空气枪噪声水平的增加，鱼类通过游到水柱底部并以更紧密的群体游动来做出反应。在空气枪噪声超过 147-151 dB re 1 μPa SEL 时，观察到鱼类和鱿鱼对空气枪噪声的警报反应显著增加。随着噪声水平的增加，警报反应的发生率也有所增加。
