Under the regulations set forth by the European Union (EU), noise pollution from transportation systems—including motor vehicles, airplanes, trains, trucks, ships, and emerging urban air mobility—has become a significant concern. The Environmental Noise Directive (END) mandates substantial noise-reduction measures to be implemented by 2030. For instance, the Regulation on the Sound Level of Motor Vehicles specifies that the maximum sound level for new passenger cars (M1 category) must not exceed 68 dB(A) by 2026, necessitating a 4 dB(A) reduction compared to 2016 levels.

ATA Mute provides innovative, lightweight, and efficient solutions tailored to meet these regulatory requirements while enhancing comfort, sustainability, and performance across various transportation sectors.

 

Motor Vehicles

Noise in motor vehicles originates from multiple sources, including HVAC systems, door panels, tires, and electric vehicle (EV) heat pumps. ATA Mute addresses these challenges with the following solutions:

• Ventilation Fan Noise Reduction: Lightweight acoustic tapes (1mm thick) applied to fan housings significantly reduce low-frequency noise without compromising performance.

• Silent Door Panels: Acoustic tapes integrated inside door panels enhance noise insulation, ensuring a quieter cabin environment.

• Wheel Covers with Acoustic Solutions: These reduce road noise while maintaining aerodynamic efficiency.

• Heat Pumps in Electric Vehicles: EV heat pumps, essential for winter heating, can generate low-frequency noise. ATA Mute’s Silent Fans, Acoustic Tapes, and Compressor Jackets effectively reduce this noise, enhancing passenger comfort.

 

Trucks and Ships

Heavy-duty transportation systems like trucks and ships are significant contributors to noise pollution. ATA Mute offers:

• Exhaust Mufflers: Patented mufflers absorb more than 97% (32 dB) of noise from exhaust systems while maintaining system efficiency with no pressure drop. These mufflers are ideal for large diesel engines used in trucks and ships.

 

Rail Systems

Rail transport systems face noise challenges from sources such as HVAC systems, bogies, and station environments. ATA Mute mitigates these issues with:

• Noise Barriers: Custom-designed barriers installed along railway tracks block noise propagation, reducing disturbances for nearby residents.

• Acoustic Coatings: Applied to HVAC systems and interior train components, these coatings absorb noise by up to 90% (6–22 dB), improving passenger comfort and meeting regulatory standards.

 

Airplanes

Aircraft noise, particularly in low-frequency ranges (below 100 Hz), affects communities near airports and poses environmental challenges. ATA Mute offers:

• Mute Propellers: Silent propeller designs incorporating ultra-thin ABC mufflers reduce noise at the source, enabling quieter operations.

• Silent Aircraft Body: Acoustic tapes and panels integrated into fuselages and wings absorb and dampen noise while maintaining structural and aerodynamic performance.

• Acoustic Liners: Engine exhaust liners reduce noise propagation, ensuring compliance with noise regulations and improving the passenger experience.

 

Air Taxis and Urban Mobility

As urban air taxis become more prominent, managing noise in urban areas is critical. ATA Mute provides:

• Silent Propellers: Advanced designs that reduce noise emissions significantly, ensuring compliance with urban noise regulations.

• Noise-Absorbing Airframes: Lightweight, vibration-absorbing tapes and coatings integrated into air taxi bodies reduce emitted noise and enhance community acceptance.

 

Heat Pumps in Electric Cars

Similar to residential heat pumps, EV heat pumps generate low-frequency noise during operation, particularly in winter. ATA Mute applies its Silent Fans, Acoustic Tapes, and Compressor Jackets to minimize noise and vibration, improving passenger comfort while ensuring regulatory compliance.

By integrating these solutions across transportation sectors, ATA Mute supports compliance with EU regulations, including the Environmental Noise Directive (END), and contributes to a future of quieter, more sustainable mobility. For inquiries and further details, please contact us.
