Abstract
Low frequency signals are prone to interference from environmental noise during transmission,resulting in a decrease in signal strength and affecting the accuracy of sound source localization.In order to improve the localization ability of low-frequency acoustic signals,a low-frequency acoustic signal localization system considering feature vector constraints is proposed.The MEMS acoustic sensor is used to collect the low-frequency acoustic signals,denoise them,and then transmit them to the low-frequency acoustic signal source localization module.A low-frequency acoustic signal source localization method considering feature vector constraints is used to achieve low-frequency acoustic signal source localization.The experimental results show that the error between the low-frequency acoustic signal source localization of the system and the actual position coordinates is small,indicating that the positioning method of the system has excellent performance,high positioning accuracy,and can improve the low-frequency acoustic signal source localization ability.关键词
