A Design And Research Studio Noise For Real-time Monitoring System

Along with the depth of the development of China’s construction of spiritual civilization, entertainment and cultural needs further expand and popular entertainment, a series of acoustic products for audio and video products, and broadcast media products need higher quality requirements. Sound studio as the basis of place of recording sound, ambient noise is intrinsically linked to the quality of the recording products. As the acoustic basis of product quality protection, noise control requirements of the sound studio is very strict on the relevant indicators must meet industry-accepted level and national norms in order to put into use.The subject rise for monitoring characteristics and requirements of the sound studio, a design sound studio monitoring system can achieve real-time continuous automatic monitor unattended. The acoustic parameters of the system acquisition with higher precision microphone, through a series of data processing, and then by way of a wired communication link, the processed data to the control center for the next data reprocessing, the graph shows and data alarm count. The characteristics of this system is capable of achieving isolated from the monitoring node and the display control center, to avoid doing collected sound signal to bring a noise environment, the system can achieve a long-time automatic monitoring and data saving and counting, recording sound studio found. This article will focus on comprehensive consideration of its data accuracy and anti-jamming technology, evaluation criteria and other aspects of the monitoring system, developed a set of useful systems.The sound studio noise monitoring system is designed for sound studio noise requirements have to measure the amount of noise evaluation function of a system is divided into two parts on the hardware and software. In the hardware of the system (including measurement node, signal conditioning modules, signal acquisition and processing module), hardware design and solutions in detail were discussed by article, including the choice of the element chip application circuit design and anti-jamming design. In software design, STC12C5410AD chip and PC were used as the core, elaborated on the program such as design ideas, algorithms, and description of the flowchart.
