| 摘 要： | 在有源噪声控制系统中,由于传统扬声器具有全指向性,在控制点处获得降噪效果的同时,在声场其他区域噪声会增大.参量阵扬声器是具有强指向性的新型声频声源,可以作为有源噪声控制系统中的次级声源,以实现特定方向或区域的降噪,同时减少对声场其他区域的影响.对参量阵扬声器和传统扬声器作为次级声源的有源噪声控制系统进行了仿真实验,结果...

| Abstract: | In active noise control system,unidirectional loudspeakers are used as secondary source to reduce the sound pressure levels in the targeted locations.However,the sound pressure levels elsewhere in the sound field is likely to increase.Because of its high direction,the parametric loudspeakers can be used as secondary source in active noise control system to suppress the noise in the targeted points without augment in other areas.In this paper,the comparison of the unidirectional loudspeakers and parametric l... |
