As silent technology continues to evolve, the operating noise of ducted air conditioning units—key components in central HVAC systems—has become a major factor affecting indoor comfort. This is particularly true in environments such as residences, apartments, and meeting rooms, where users are placing higher demands on sound quality and quiet operation.

To address industry pain points—such as concentrated fan noise frequencies and the limitations of traditional passive sound insulation—AncSonic has developed a highly integrated active noise cancellation (ANC) solution, leveraging years of expertise in intelligent acoustics. This breakthrough provides a new path for the acoustic upgrade of ducted AC units.

AncSonic’s ANC module is custom-designed to fit directly into the air outlet structure of ducted units. It requires minimal installation space and integrates a complete system—including high-sensitivity microphones, dedicated speakers, and a customized noise control board. Without altering the air duct layout or the external design, the module ensures seamless integration with excellent engineering compatibility and plug-and-play usability.

On the technical side, the solution features a hybrid ANC architecture capable of real-time sensing of airflow noise and generating inverse sound waves to effectively cancel out unwanted noise. The system adapts intelligently to variable conditions such as fan speed and airflow, maintaining consistent performance across multiple operating scenarios.

The noise cancellation system has been precisely optimized for the 200Hz–1500Hz frequency range, delivering exceptional attenuation especially in the sub-1000Hz band where fan noise typically peaks. It achieves up to 16dB of noise reduction, significantly improving the quietness and relaxation of indoor environments.

Beyond noise control, the system is also engineered for future scalability. With reserved interfaces for Bluetooth audio playback and integration of high-performance audio DSP chips with advanced algorithms, it supports low-latency response and energy-efficient operation, creating a robust technological foundation for smart interaction capabilities.

Noise cancellation is no longer just a supplementary feature—it is fast becoming a core competency in modern HVAC equipment. Backed by continuous breakthroughs in active acoustic control, AncSonic offers a practical, forward-looking solution that combines engineering flexibility with cutting-edge algorithmic power. This ANC solution is poised to extend across more air conditioning systems, enabling the industry to move toward a quieter, smarter future—delivering truly peaceful spaces and intelligent living experiences.
