On October 30, 2025, the 7th "Golden Collection Award" ceremony hosted by GAC Motor came to a successful conclusion in Shanghai. As an authoritative award in the field of automotive suppliers, the Golden Collection Award aims to "discover good companies, promote good technology, and achieve automotive professionals". With outstanding innovation and mass production capabilities in the field of intelligent cockpit acoustics, Huayanhui Sound's RNC active road noise reduction technology stood out from thousands of candidate companies and successfully won the "Best Technology Practice Application Award". This honor is not only a high recognition of the deep cultivation achievements of Huayan Huisheng in the field of automotive intelligent acoustics technology, but also marks a key milestone for domestic active noise reduction technology to enter the leading camp in industry competition.

Technological breakthrough: From RNC to ERNC, reconstructing a new benchmark for cabin quietness

With the rapid development of new energy vehicles, the high-frequency noise of electric drive systems and the low-frequency road noise caused by tires and road surfaces have become the core pain points that restrict the upgrading of driving experience. Compared with traditional passive sound absorption and insulation methods, RNC active noise reduction technology uses real-time acquisition and calculation of vehicle vibration and noise signals, and utilizes the sound system to release reverse sound waves for precise cancellation, reconstructing the cabin acoustic environment from the root, and bringing passengers a more advanced sense of tranquility and immersion. Huayanhui Sound has been focusing on the research of acoustic algorithms and vehicle integration technology for many years. In 2024, it was the first to achieve a breakthrough in the localization of RNC technology and launched the first domestic RNC active noise reduction system integrated into the vehicle intelligent cabin domain control platform, which has completed mass production and landing. This achievement not only breaks the long-term technological monopoly of international brands in this field, but also helps more Chinese automakers quickly build differentiated competitiveness in cabin acoustics with the advantages of "strong performance, excellent cost, and good service". In 2025, Huayanhui Sound further launched an upgraded version of ERNC integrated engine noise and road noise coupling control technology. This technology achieves collaborative suppression of engine noise and road noise under complex operating conditions with ultra-low latency of 1 millisecond through multi-source coupling algorithm optimization and domain control level computing power improvement. It can achieve a noise reduction effect of over 15dB, significantly improving the overall acoustic smoothness and cabin quietness experience of the vehicle. The global debut and mass production of this technology not only sets a new performance benchmark in the field of active noise reduction, but also fully reflects the forward-looking layout and innovative strength of Huayanhui Sound in the direction of intelligent automotive acoustics.

Industrial value: Breaking the deadlock with "sound", empowering the transformation of high-end vehicles

In the current deep transformation of the automotive industry towards intelligence and comfort, the "quietness" inside the car has become an important indicator for measuring the luxury and quality of the entire vehicle. The mature application of RNC technology not only brings users a "perceptible and comparable" driving experience improvement, but also promotes the high-end transformation and upgrading of vehicle manufacturers in the field of intelligent cabin comfort. To ensure precise matching of technology with vehicle requirements, Huayanhui Sound has accumulated rich experience in mass production and calibration data by deeply participating in joint development and adaptation verification with multiple OEMs, forming a mature technology implementation system. At present, the RNC and ERNC series solutions have been applied to multiple mid to high end new energy vehicles and flagship models of domestic brands, receiving unanimous praise from OEMs. Behind this series of achievements is the continuous cultivation of "industrialization capability" by Huayanhui Sheng. The company has established a full chain acoustic innovation loop covering "algorithm research and development → hardware adaptation → domain control integration → vehicle calibration", truly achieving dual leadership in technological innovation and stable delivery, providing solid support for promoting the high-quality development of China's automotive industry.

Original aspiration like a rock: driving the evolution of the automotive acoustics industry through continuous innovation

At the award ceremony, Mr. Han Qiang, co-founder and CEO of Huayan Huisheng, represented the company to receive the award on stage. He stated that this award is not only a high recognition of Huayan Huisheng's long-term focus on acoustic innovation and independent research and development, but also a core driving force for us to continue breaking through technological boundaries and leading industry upgrades. Looking towards the future, Huayanhui Sound has always adhered to the core strategic rhythm of "mass production of one generation, release of one generation, and pre research of one generation". Against the backdrop of constantly increasing technological iteration speed and system integration complexity, it continuously strengthens its engineering development and system integration capabilities, and maintains leadership through continuous innovation. At the same time, we will deepen ecological collaboration with vehicle manufacturers, chip manufacturers, and domain control partners, promote the multi scenario application and rapid iteration of active noise reduction technologies such as RNC and ERNC, build intelligent acoustic full stack capabilities, and create a more peaceful, comfortable, and intelligent travel space for users.
