There is increasing scientific recognition that marine invertebrates are sensitive to the particle motion component of underwater sound. As part of the EU-funded interdisciplinary SATURN research project, a specialized experimental laboratory system was developed, the AquaVib. The core components of this system include a transparent acoustic chamber equipped with sensors for sound pressure, particle acceleration, dissolved oxygen, and temperature. The chamber is enclosed at both ends by a pair of 1 kN electrodynamic (ED) shakers. These shakers allow us to reproduce low-frequency sounds within the enclosed water volume, similar to underwater radiated noise (URN). The control in the relative phase between the pair of ED shakers in two different configurations, that is, 0 and 180°, permits the reproduction of a sound field at different kinetic-to-potential (K-to-P) energy ratios, that is, varying the pressure and particle motion components of sound exposure, providing a multimodal approach to investigate physiological, pathological, and ultrastructural effects of noise on invertebrate species at any of their life stages. The primary objective of the device presented in this chapter is to identify and quantify the risks, as well as the acute and long-term impacts, of anthropogenic noise exposure on marine invertebrates and fishes, while separately assessing the effects of acoustic pressure and particle motion.

摘要

There is increasing scientific recognition that marine invertebrates are sensitive to the particle motion component of underwater sound. As part of the EU-funded interdisciplinary SATURN research project, a specialized experimental laboratory system was developed, the AquaVib. The core components of this system include a transparent acoustic chamber equipped with sensors for sound pressure, particle acceleration, dissolved oxygen, and temperature. The chamber is enclosed at both ends by a pair of 1 kN electrodynamic (ED) shakers. These shakers allow us to reproduce low-frequency sounds within the enclosed water volume, similar to underwater radiated noise (URN). The control in the relative phase between the pair of ED shakers in two different configurations, that is, 0 and 180°, permits the reproduction of a sound field at different kinetic-to-potential (K-to-P) energy ratios, that is, varying the pressure and particle motion components of sound exposure, providing a multimodal approach to investigate physiological, pathological, and ultrastructural effects of noise on invertebrate species at any of their life stages. The primary objective of the device presented in this chapter is to identify and quantify the risks, as well as the acute and long-term impacts, of anthropogenic noise exposure on marine invertebrates and fishes, while separately assessing the effects of acoustic pressure and particle motion.
