我们结合工程特点,研制一种新的中空立体吸声体,通过试验和试点工程应用的结果,表明本吸声体具有良好的吸声特性,吸声频带宽,基本上能满足电影厂录音工作频率的范围,能够有效、灵活地控制和调节室内混响时间达到最佳频响特性,由于吸声体具有较高的吸声效率,施工简便、装饰性好,用于工厂车间降低噪声也较为有效,值得推广。
Based on the engineering characteristics, we developed a new hollow stereo sound absorber. The results of the experiments and pilot projects show that the sound absorber has good sound absorption characteristics and sound absorption bandwidth. It can basically meet the needs of cinema recording work Frequency range, can effectively and flexibly control and adjust the indoor reverberation time to achieve the best frequency response characteristics, the absorber has a high sound absorption efficiency, easy construction, good decorative, for the workshop to reduce noise is also more Effective, worth promoting.
