Design of Building Engineering Weak Current Intelligent System Based on Sound Enhancement Technology
In order to optimize indoor acoustic environment,an intelligent weak current system based on sound enhancement technology for building engineering is developed.The system is composed of three modules,in which the environmental sound monitoring and analysis module monitors the environmental sound in real time,and uses adaptive filtering and wavelet transform for noise reduction and feature extraction.The sound enhancement and propagation control module uses Digital Signal Process(DSP)chip and speaker array to realize accurate sound enhancement and spatial audio processing.Intelligent decision and response module is based on Q-learning algorithm to realize intelligent optimal control of sound environment.The experimental results show that the system can obviously improve the speech transmission index and user satisfaction of the conference hall.
