Aeroacoustics noise, particularly in the aviation and wind turbine industries, poses significant challenges due to its low-frequency nature and the broad range of frequencies it encompasses. Aircraft noise, primarily below 100 Hz, and wind turbine noise, typically between 20 Hz and 400 Hz, not only disturb the environment but also cause health concerns such as sleep disturbances and stress for those living nearby. ATA Mute's cutting-edge solutions effectively address these issues, integrating innovative designs with proven noise reduction technologies.

 

Acoustic Panel

The acoustic panels developed by ATA Mute offer exceptional sound absorption across a wide range of frequencies, particularly effective in reducing ultra low-frequency aeroacoustics noise. These panels are designed to be applied to large surfaces, such as the interior linings of wind turbine nacelles or aircraft cabins, to minimize noise transmission and enhance acoustic performance.

 

Acoustic Tape/Coating

ATA Mute’s acoustic tape is a highly versatile solution that can be applied to airfoil surfaces, blades, and other aerodynamic structures. This custom-designed coating significantly reduces aeroacoustics noise at the source by absorbing up to 90% of the sound energy across targeted frequency ranges. It is ideal for use on propellers, wind turbine blades, and aircraft wings, effectively mitigating the propagation of noise into the environment.

 

Design of Silent Fans

Axial fans, often used in cooling systems for aviation or in wind turbines, are major contributors to aeroacoustics noise. ATA Mute specializes in the design of silent fans, reducing noise levels by up to 14 dB without compromising performance. This technology applies advanced blade designs, including serrations, perforations, and optimized geometries, to ensure quieter operation while maintaining efficiency.

 

Silent Body/Cover

ATA Mute’s Silent Body/Cover is a revolutionary solution that combines structural strength with exceptional acoustic absorption. Designed for the bodies of airplanes, wind turbines, and aerodynamic blades, our technology enables the replacement of traditional metallic or composite casings with advanced materials that are lightweight, durable, and highly efficient in capturing aeroacoustics noise. These materials not only provide sufficient structural integrity but also absorb at least 6 dB noise. By integrating sound-absorbing properties directly into the structural components, the Silent Body/Cover ensures a quieter operational environment while maintaining aerodynamic and mechanical performance. Additionally, our solution contributes to sustainability by using recyclable materials, offering both environmental and acoustic benefits.

 

Patented Innovations

ATA Mute’s patented Anechoic Broadband Compact (ABC) mufflers provide groundbreaking solutions for absorbing aeroacoustics noise from rotating machinery and aerodynamic systems. These ultra-thin mufflers use advanced thermo-viscous damping mechanisms to achieve up to 99.9% noise absorption. Their integration into fan blades, ducts, or airfoil surfaces ensures a substantial reduction in low-frequency noise, enhancing the operational environment and public acceptance of these technologies.

 

Impact on Aeroacoustics Applications

By reducing the low-frequency noise generated by wind turbines and aircraft, ATA Mute’s products contribute significantly to environmental and societal well-being. These technologies help address public opposition to wind power projects, enhance passenger comfort in aviation, and minimize the health risks associated with noise pollution.
