Abstract:
To monitor environment noise,are try to design an intelligent noise monitoring system which can measure,store,calculate and analyze the common noise rating quantity,such as LN,Leq,Lnp,TNI,Ldn,SD and so on.The design proposal,block diagram and the software flow pattern are written in this paper,which also focus on the design and realization of the main hardware circuit and the functions of software.At the same time,the experiment proves that the instrument works well and achieves the expected design objectiv...
