基于主动噪声控制技术的校园房屋建筑减噪装置OA

With the rapid development of urbanization and population growth,the environmental noise around campus buildings has gradually become a serious problem,which has brought trouble and discomfort to the study and work of students and staff.The traditional sound insulation measures can not solve the noise source itself,so it is necessary to develop a device that can actively reduce noise.This paper presents a noise reduction device for campus buildings based on active noise control technology.The device can reduce or eliminate the noise by collecting the environmental noise signal and generating the opposite acoustic signal by using the phase and spectrum information.The device consists of a noise sensor,a signal processor,a loudspeaker system and a control system,which can adjust the output of the loudspeaker system in real time to achieve the best noise reduction effect.Through the introduction of campus building noise reduction device based on active noise control technology,the adverse impact of environmental noise on students and staff can be effectively reduced,and a more quiet and comfortable learning and working environment can be created.However,the performance and feasibility of the device still need further research and practical verification.In the future,the design of the device can be further optimized and its potential in a wider range of applications can be explored.
