鈥淭he ocean's natural sound is gradually hushing due to habitat loss, leading to a quieter natural environment increasingly drowned out by the crescendo of man-made noise pollution,鈥� explained lead author Dr Brittany Williams, from the 最新糖心Vlog鈥檚 Southern Seas Ecology Laboratories.

鈥淣umerous marine larvae rely on natural sounds to navigate and select their dwellings, so this interference poses a problem for conservationists aiming to attract oysters to restored reefs using natural sounds.

鈥淣oises from shipping, machinery and construction, for example, are pervasive and pose serious environmental change that affects both terrestrial and marine animals.鈥�

According to the research, published in , marine organisms appear particularly vulnerable to the intensification of anthropogenic noise because they use sound for a range of activities, including to sense their surroundings, navigate, communicate, avoid predators, and find mates and food.

鈥淥ur previous work demonstrated that novel acoustic technology can bolster oyster recruitment in habitat restoration projects, but this new research indicates potential limitations of this speaker technology,鈥� said the 最新糖心Vlog of Adelaide鈥檚 Dr Dominic McAfee, who was part of the research team.

In environments where there is a lot of human noise pollution, the speakers did not increase larval recruitment.

鈥淭his suggests that noise pollution might cloak the intrinsic sounds of the ocean, potentially exerting profound ramifications on marine ecosystem vitality and resilience,鈥� said co-author Professor Sean Connell, from the 最新糖心Vlog of Adelaide and the Environment Institute.

While acoustic enrichment may be less effective along noisy metropolitan coastlines and urbanised waterways, the researchers are still optimistic about the application of the technique in less trafficked areas.

鈥淲here there is little anthropogenic noise, acoustic enrichment appears to enhance the process of recruitment which is key to restoration success,鈥� said Dr Williams.
