Underwater noise presents a significant threat to marine life and ecosystems, disrupting vital functions such as communication, navigation, feeding, reproduction, and overall survival. It also affects human activities that rely on underwater systems. Marine creatures heavily depend on sound for communication, navigation, hunting, and threat detection. However, increased human activities like shipping, offshore construction, and naval operations have introduced substantial anthropogenic noise into the oceans. This noise pollution disrupts marine species' behaviors, leading to issues like stranding, reduced reproductive success, and altered migration patterns.

For instance, ships with submerged propellers generate underwater noise, which can be disruptive for both the ship's crew and passengers, as well as marine life such as fish, dolphins, and whales. This noise can reach high levels, especially when cavitation occurs due to the propeller reaching high speeds, causing the water to undergo a phase transition into water vapor. Cavitation noise is a well-known issue for ships and emits underwater noise that can be harmful to marine life. Thus, taking urgent action to reduce or mitigate underwater noise is imperative.

At ATA Mute, we take responsibility for minimizing the adverse effects of underwater noise by addressing its source. Our simulations have shown that our patented ultra-thin ABC mufflers can effectively work in various fluid environments, including normal water and seawater. We are currently in the process of conducting laboratory tests to integrate ABC mufflers with ship propellers. Additionally, as mentioned in other sections, our technology can be applied to onboard ship components to reduce noise from sources such as HVAC systems and ship engines.
