摘要
主要介绍了小型录音室的音质要求及声学设计方法,根据小空间中声场特点着重对混响时间的频率特性及声扩散等声学要求进行了设计,为满足录音对信噪比的要求,设计中采用了综合降噪措施,降低室内背景噪声,通过验收测试数据及使用人员评价,说明各项声学指标满足声学要求及使用要求。
The paper mainly introduces the requirements of the sound quality and the acoustic design methods for the small recording room,emphasizes on the design,including the frequency features and the sound diffusion of the reverberation time according to the sound field characters of the small space to meet the requirements of the signal-to-noise ratio of the record,adopts the comprehensive measures to the noise reduction to lower the background noises indoor,and indicates all the acoustic indexes meet the requirements of acoustics and usages according to the reception test data and the evaluation of the personnel.
