The difference between three-dimensional active noise reduction technology and single-point active noise reduction technology Ansheng Technology completed tens of millions of A round of financing

Beijing Ansheng Technology has successfully closed a multi-million RMB Series A funding round. The investment came from Northern Light Venture Capital and Xiangfeng Investment, a subsidiary of Singapore's Temasek. As a global leader in active three-dimensional space noise reduction solutions, Ansheng has been backed by top-tier venture capital firms such as Jiuhe Venture Capital, Rich Capital, Taihuo Technology, and Tycoon since its establishment in 2016. Liu Yifan, founder and CEO of Ansheng Technology, stated that the company will focus on product development, market expansion, and team growth following the successful fundraising. In 2017, Ansheng signed a strategic partnership with Yunmi Technology, a major player in the Xiaomi ecosystem, to develop an active noise reduction system for range hoods. The company also collaborates with well-known home appliance brands like Haier, Dreamer Fresh Air, and AIRMX Fresh Air. Xu Yinhai, co-founder of Ansheng Technology, explained that unlike single-point active noise reduction technology, three-dimensional active noise reduction involves analyzing and modeling the entire sound field. This approach allows for more effective handling of complex noise problems in environments such as homes and vehicles. Noise can have serious long-term effects on the central nervous system, impacting overall health. Active noise reduction technology was developed to combat this issue. Creating a quiet and comfortable living and driving environment is a fundamental desire for many people. Prolonged exposure to noise can affect the brain’s central nervous system through the auditory pathway, leading to various physical and mental health issues. With advancements in active noise reduction technology, it is becoming one of the most efficient solutions to tackle noise pollution across multiple industries. Beijing Ansheng Technology is the first domestic provider specializing in three-dimensional space active noise reduction technology. It utilizes cutting-edge digital signal processing and acoustic holography to offer comprehensive sound quality improvement solutions to manufacturers. The key difference between three-dimensional active noise reduction (3D ANC) and single-point ANC lies in their application scope. Traditional passive noise reduction relies on physical barriers to block noise, which often fails to address low-frequency sounds and can negatively impact airflow and heat dissipation. In contrast, active noise reduction uses microphones to detect noise and emits counter-waves to cancel it out during propagation. Single-point ANC targets only the user's ear, typically used in headphones. However, 3D ANC requires advanced algorithms and deep acoustic knowledge to manage noise across entire spaces. This makes it suitable for applications in automotive, aerospace, rail, home appliances, and more. Ansheng Technology’s core technology stems from the prestigious Ray W. Herrick Laboratory in the U.S., known for its research in acoustics. This lab has worked with companies like Rolls-Royce, General Motors, and Midea for over 60 years. Ansheng’s proprietary algorithm significantly improves computational efficiency and extends the noise reduction frequency range to 2100Hz—more than double the industry standard. Their products, such as AS-Hood, AS-Fan, and AS-Air, help household appliances balance performance and noise levels effectively. The future of 3D active noise reduction looks promising. Its integration into automotive and home appliance sectors will enhance user experience and reduce health risks associated with prolonged noise exposure. Soon, Ansheng’s technology may become a common feature in everyday products. The founding team of Ansheng Technology includes experienced professionals from renowned companies like Huawei and LeTV, as well as academic experts from Purdue University. Liu Yifan, the CEO, graduated from Beijing University of Aeronautics and Astronautics and previously worked at Huawei. His twin brother, Liu Yangfan, serves as CTO and is a research professor at Purdue University. He developed a high-order multi-level sub-sound field simulation model, earning recognition from *Applied Acoustics*, the leading journal in acoustics. Xu Yinhai, another co-founder, comes from LeTV, bringing strong technical expertise. Shi Rui, the market partner, has extensive experience from Huawei and offers valuable industry insights. Together, they form a powerful team driving innovation in active noise reduction.
