Active Noise Cancellation – From Modeling to RealTime Prototyping

Active noise control (ANC), also known as active noise cancellation, attempts to cancel unwanted sound using destructive interference. ANC systems use adaptive digital filtering to synthesize a sound wave with the same amplitude as the unwanted signal, but with inverted phase. • This video first reviews the basic principles of ANC. It then shows how to use Simulink® to design and simulate an ANC system to cancel noise within a pipe model using a Filtered-X NLMS adaptive filter. Finally, you’ll see how to implement the ANC system using a real-world duct pipe and a Speedgoat real-time audio machine equipped with an ultra-low latency operating system and ultra-low latency A/D and D/A converters. The video shows how you can use automatic C code generation to go from the simulation model to the real-time prototype. • Explore the example used in this video: https://bit.ly/31bTp9z • Other Resources • Adaptive Filters: https://bit.ly/339uGor • Presentation by ASK Industries at MATLAB EXPO 2018: https://bit.ly/2KgwIvD • -------------------------------------------------------------------------------------------------------- • Get a free product Trial: https://goo.gl/ZHFb5u • Learn more about MATLAB: https://goo.gl/8QV7ZZ • Learn more about Simulink: https://goo.gl/nqnbLe • See What's new in MATLAB and Simulink: https://goo.gl/pgGtod • © 2019 The MathWorks, Inc.
