摘要
结合江阴广电中心大型演播室声频工程设计与施工的实际,完成了演播室的声学测试,包括混响时间、最大声压级、传声增益、声场不均匀、传输频率特性、总噪声级、语言传输指数等性能指标,对测试数据作了详细分析,并针对演播室的听音评价测试,给出了评价结论。
Combined with the electroacoustic system design and construction of large-scale television studio practiee in Jiangyin broadcasting and television center, the studio acoustic test is completed, including the reverberation time, maximum sound pressure level, sound transmission gain, sound field uneven, transmission frequency characteristics, the total noise level, speech transmission index and other performance indicators. A detailed analysis of the test data is given, and according to the listening evaluation test of the studio, the conclusion is carried out.
