I nterior noise of EMU active control syste m based on DSP
摘要
Abstract
Due to the massive use of high-speed railway,running noise increases with speed,seriously affecting the comfort of the staff exposed to the operational environment.A DSP-based active noise control system was de-signed.The system consisted of the DSP part and the audio part.The DSP part took TMS320VC5509A as a core, expanding SDRAM memory modules and power supply modules.The audio part takes TLV320AIC23B as a core, building voice input and output modules.DSP used I2C for communication with AIC23B,which was two-wire and master-slave way.DSP calculated the input from AIC23B and returned the output,while observing the effect in real time via the PC.The noise amplitude decreased obviously after using the system.Experimental results show that the DSP-based active noise control system can effectively reduce interior noise of EMU.Broadband noise reduction needs to be improved.关键词
