Research on Optimizing the Layout of Secondary Speakers for Indoor Active Noise Cancellation

With the rapid development of industrialization and urbanization, noise pollution has become a significant factor affecting people’s quality of life and health. Active noise control (ANC) technology has garnered widespread attention due to its superior performance in controlling low-frequency noise. This paper proposes an active noise cancellation system based on the optimization of secondary sound source layout, which enhances the system’s noise reduction effect and stability by optimizing the position of secondary sound sources and algorithm parameters. Experimental results indicate that the system demonstrates good noise reduction performance in various complex sound field environments, holding important practical application value.
