摘　　要：在电视播出系统中,音频信号传输常遇信号丢失、噪声侵扰及音量不均衡等问题,影响音频品质与观众体验。对此,分析音频信号异常的表现及根源,提出解决方案。信号丢失与硬件故障、线路异常及外部干扰有关,噪声侵扰由环境噪声、设备老化及线路问题所致,音量不均衡与设备兼容、增益调控不当相关。可采用的应对措施包括优化处理流程、引入自适应滤波技术、加强监测与维护等。In the television broadcasting system,the audio signal transmission often encounters problems such as signal loss,noise intrusion and volume imbalance,which affect the audio quality and audience experience.In this regard,this paper analyzes the performance and root causes of audio signal anomalies,and puts forward solutions.Signal loss is related to hardware failure,abnormal line and external interference,noise intrusion is caused by environmental noise,equipment aging and line problems,and uneven volume is related to equipment compatibility and improper gain control.Possible countermeasures include optimizing the processing process,introducing adaptive filtering technology,and strengthening monitoring and maintenance.
