Underwater noise presents a significant threat to marine life and ecosystems, disrupting essential functions such as communication, navigation, feeding, reproduction, and overall survival. Marine creatures rely heavily on sound for these vital activities, but anthropogenic noise—caused by shipping, offshore construction, and naval operations—has introduced substantial challenges. This noise pollution disrupts marine species' behavior, leading to issues like stranding, reduced reproductive success, and altered migration patterns.

Ships with submerged propellers are a primary source of underwater noise, affecting not only marine life such as fish, dolphins, and whales but also human activities reliant on underwater systems. Cavitation, a common phenomenon caused by high propeller speeds, generates significant underwater noise when water transitions into vapor. This noise can disrupt marine ecosystems, degrade passenger experiences, and reduce crew comfort.

At ATA Mute, we are committed to minimizing the adverse effects of underwater noise by addressing it directly at the source. Our innovative solutions utilize cutting-edge materials and designs to mitigate noise across a variety of marine applications.

 

Engine and Propeller Noise Reduction

• Exhaust Mufflers: ATA Mute has developed prototypes of exhaust mufflers that achieve more than 80% absorption of noise without causing pressure drops. These mufflers are designed with either a low reflection coefficient or a low transmission coefficient, ensuring minimal acoustic energy is emitted or transmitted.

• Propeller Noise Mitigation: Our patented ultra-thin ABC mufflers and acoustic tapes have been successfully tested in fluid environments, including seawater. By integrating these technologies with ship propellers, cavitation noise is significantly reduced, protecting marine life and improving onboard comfort.

 

Luxury and Sustainability for Yachts

For yachts and leisure boats, ATA Mute provides noise reduction solutions that blend luxury and functionality:

• Customizable Acoustic Panels and Tapes: Designed with high-end finishes such as leather, our solutions reduce noise while complementing the yacht's aesthetic.

• Silent Propellers: Innovative propeller designs minimize noise emissions, ensuring a quiet and pleasant journey for passengers.

 

Noise Barriers and Acoustic Panels

Noise from engine rooms, HVAC systems, and other onboard components can disrupt both passengers and marine life. ATA Mute offers:

• Noise Barriers: Engineered barriers for ship engine rooms and machinery enclosures to block noise propagation.

• Acoustic Panels: These panels absorb up to 95% of noise, ensuring a quieter environment for passengers and crew.

 

Marine HVAC Systems

HVAC systems aboard ships and submarines generate secondary noise that contributes to overall onboard disturbances. ATA Mute addresses this with:

• Acoustic Tapes and Coatings: Applied to HVAC casings and ducts, these reduce operational noise by 6-10 dB without affecting performance.

 

Eco-Friendly and Sustainable Solutions

ATA Mute's technologies are designed with sustainability in mind:

• Reduced Underwater Noise Pollution: Our solutions protect marine life by mitigating noise emissions from ships, submarines, and other underwater systems.

• Sustainable Materials: Lightweight, durable, and recyclable materials ensure that our technologies align with global sustainability goals.

 

Ongoing Innovations

We are conducting laboratory tests to further integrate our patented ABC mufflers with ship components. Our goal is to create exhaust ducts with high absorption capabilities that neither reflect nor transmit acoustic energy. These innovations ensure compliance with environmental regulations while enhancing onboard comfort and marine ecosystem protection.

By integrating ATA Mute's advanced underwater noise reduction solutions, marine vessels and underwater systems can achieve quieter, more efficient operations while safeguarding the marine environment. For further information, please do not hesitate to contact us.
