摘要
对北京和长沙两地某高端KTV会所内的扩声系统声学特性进行了测量和音质主观评测,并进行了对比分析,结合长沙会所现场的声学情况进给出了声学改进意见。对改造前后长沙会所的混响时间频率特性、本底噪声、声场不均匀度、传输频率特性、传声增益等声学指标进行了客观测量和主观评价,结果表明对长沙某高端KTV会所的声学改造效果明显。通过该项目总结了此类场所在声学上值得注意的问题。
The acoustic properties of two high - end KTV club amplification systems are measured and the subjective eval- uation of their sound quality are also analyzed. According to the acoustic environment of Changsha club and the results of the measurements, a series of acoustic improvement suggestion are given. The frequency characteristics of reverberation time, to- tal noise level, transmission frequency response, transmission gain, sound distribution and the sound quality of Changsha KTV club are measured again after the implementation of the reform measures. The results show that the improvement of the acoustic effect at Changsha KTV club is obvious and summarizes on some of the acoustic problems that worth to pay attention at such places.
