Beijing Ansheng Technology announced the completion of tens of millions of A round of financing. The investors are Northern Light Venture Capital and Singapore ’s Temasek wholly-owned subsidiary Xiangfeng Investment. Ansheng Technology is a leading international provider of active three-dimensional space noise reduction Solutions. Since its establishment in 2016, it has been led by Jiuhe Venture Capital, Rich Capital, and many institutions including Taihuo Technology and Tycoon .
Liu Yifan, founder and CEO of Ansheng Technology, said that after the completion of this round of financing, he will focus on product development, promotion and team expansion. In 2017, Ansheng Technology has signed a strategic cooperation agreement with Yunmi Technology, a millet industry chain enterprise, to help it create an active noise reduction system on top suction hoods. At the same time, cooperate with many well-known home appliance manufacturers such as Haier, Dreamer Fresh Air, AIRMX Fresh Air and so on.
An Yin Technology co-founder Xu Yinhai said: Unlike single-point active noise reduction technology, three-dimensional active noise reduction must consider the analysis and modeling of the three-dimensional sound field. The noise separation algorithm can effectively deal with the noise problems of three-dimensional space fields such as home appliances and automobiles.
Noise affects the central nervous system of the brain and accumulates over time, threatening health. Active noise reduction technology came into being.
Having a quiet and warm home and driving environment is one of the basic wishes of people to achieve a better life. In fact, the impact of noise on humans is by no means limited to subjective feelings. Living in a noisy environment for a long time, the noise will act on the central nervous system of the brain through the hearing organs, which will affect the body tissues. With the development of active noise reduction technology and the application of this technology in various consumer products, it will become one of the most effective means to solve the noise problem.
Beijing Ansheng Technology Co., Ltd. is the first domestic solution provider focusing on three-dimensional space active noise reduction technology, using internationally leading digital signal processing technology and acoustic holography technology, is committed to providing manufacturers with a comprehensive range of sound quality improvement solutions.
The difference between 3D active noise reduction technology and single point active noise reduction technologyThe traditional noise reduction method is called passive noise reduction, which refers to blocking noise absorption to achieve noise reduction. However, the heavy acoustic package not only does not help the annoying low-frequency noise, but also affects the air output and heat dissipation performance of exhaust appliances. Active noise reduction (ANC) technology refers to the use of microphones to listen to noise sound waves and send out reverse sound waves after processing. The two interfere with each other during the propagation process to achieve noise reduction technology.

Active noise reduction technology is also divided into single-point active noise reduction technology and three-dimensional active noise reduction technology. The main difference in application is that: single-point ANC technology only covers the single point of the human ear, which requires wearable headphones and ears. Covers are used as carriers. The endless active noise reduction headphones on the market are products of single-point ANC technology.
The three-dimensional space active noise reduction technology needs to have excellent active noise reduction algorithm foundation, but also requires a deep acoustic theory background, analysis, simulation, and noise reduction of the three-dimensional space sound field in order to achieve specific The area achieves the effect of active noise reduction, thereby greatly expanding the scope of application. Typical application scenarios are: military industry, aviation, high-speed rail, automobiles, home appliances, IT, industry, etc.
The core technology of Ansheng Technology originates from the prestigious American Ray W. Herrick Laboratory
At present, only five companies in the world have mature three-dimensional space active noise reduction solutions, most of which only apply to their own car audio, and can only deal with low-frequency noise below 300Hz.

The core technology of AAC comes from the well-known American Ray W. Herrick Laboratory in the field of acoustics. This laboratory has served Rolls-Royce, General Motors, Ford, Midea and many other well-known enterprises for more than 60 years. Ansheng Technology's unique algorithm greatly improves the calculation efficiency of the three-dimensional sound field, and expands the frequency range of noise reduction to 2100Hz, which is more than 2 times the highest level in the industry. The noise reduction solutions AS-Hood, AS-Fan, and AS-Air that have been released for household appliances can help household appliances such as range hoods, air purifiers, and fresh air solve the contradiction between air volume and noise.
Prospect of Active Sound Technology's 3D space active noise reduction technologyThe introduction of three-dimensional active noise reduction technology to the automotive, home appliance and other industries will bring consumers a more comfortable product experience. In addition, the application of this technology will also help users who are exposed to noise for a long time to reduce the noise caused by noise. Hidden health risks, I believe that in the near future, products equipped with the three-dimensional active noise reduction technology provided by Anson Technology will be everywhere.
The founding team of Ansheng Technology comes from well-known enterprises in the industry such as Huawei and LeTV and Purdue University
Ansheng Technology founder and CEO Liu Yifan graduated from Beijing University of Aeronautics and Astronautics, and previously worked at Huawei Technologies Co., Ltd. Ansheng Technology CTO and Chief Scientist Liu Yangfan is also a research professor at Purdue University in the United States. It is worth mentioning that Liu Yifan and Liu Yangfan are twin brothers. The theoretical model of the high-order multi-level sub-sound field simulation mentioned above is by Liu Yangfan Founded, and thus was rated as a professional reviewer by Applied AccusTIc, the most authoritative academic journal in the acoustic world. In addition, Xu Yinhai, the co-founder of An Sound Technology, comes from LeTV and has extensive experience in technology development and project management. Market operation partner Shi Rui is from Huawei and has extensive market experience and keen industry insight.
