Huawei's Cloud-Based Active Noise Cancellation Revolutionizes Automotive Acoustics
Huawei's Shanghai Acoustics R&D Centre has developed a cutting-edge active road-noise cancellation system, utilising cloud computing for real-time processing. This innovation, led by Chief Automotive Sound & Acoustics Advisor Lars Goller, is set to revolutionise automotive acoustics, with BYD (Build Your Dreams) being the first brand to invest in this technology.
The system continuously processes sensor data, facilitated by the cloud, to cancel out road noise in real-time. It relies on independent sound-zone technology, which requires instantaneous DSP adjustments based on wave interference patterns calculated in real-time.
The development process involved extensive audio measurements, listening sessions, and the application of psychoacoustic principles. Huawei's investment in R&D, totalling CNY 179.7 billion (approximately £20 billion / €23.4 billion) in 2024, has enabled such innovative solutions. With over 113,000 R&D employees, the company processes massive acoustic datasets and runs simulations to enable real-time audio processing.
Huawei supplies these solutions to over twenty automakers, covering driver assistance, cockpit and control systems, and acoustics. The centre's cloud-computing infrastructure processes variables and runs simulations that would overwhelm local processing capabilities, demonstrating its scalability and cost-effectiveness.
Huawei's active road-noise cancellation system, developed under the leadership of Lars Goller, is set to enhance the driving experience for BYD customers. This technology, facilitated by cloud computing, showcases Huawei's commitment to innovation and its impact on the automotive industry.
