Analysis and Solutions for Common Audio Issues in Conference Sound Reinforcement Systems

ZHU Shuting (Henan Natural Resources Comprehensive Security Center,Zhengzhou 45OO16, China）

Abstract: [Purposes] This paper analyzes the causes of common audio faults in sound reinforcement systems and seeks appropriate solutions to eliminate and avoid adverse effects caused by system failures, thereby ensuring conference quality.[Methods] First,understand the working principles of various acoustic devices and the overallarchitecture of the venue's sound reinforcement system to familiarize with the acoustic environment.Next,deploy specialized sound measurement equipment for on-site simulation tests to replicate audio faults and systematicall investigate their causes.During troubleshooting, employ the substitution method,bypass method,or elimination method to isolate and analyze issues.Solutions may include replacing faulty cables,adjusting audio device parameters,optimizing venue layout, or enhancing technician training.[Findings] Corresponding solutions should be applied based on fault causes.For instance: microphone feedback requires adjusting the relative positions of microphones and speakers; low-to-mid frequency electromagnetic interference necessitates checking the grounding of the sound reinforcement system;high-frequency wireless signal interference demands identifyingand avoiding the interference source.[Conclusions] The sound reinforcement system is an integrated complex involving sound capture,processing,transmisson,and amplification.Familiarity with common faults and appropriate countermeasures enables efficient troubleshooting,improving conference efficiency and quality.

Keywords: audio faults;conference sound reinforcement; noise cause analysis
