| 中文摘要: |
| 本文对一种三扬声器重发系统中倾听者所在区域的声场进行了分析。结果表明:采用该三扬声器系统重发声信号,其听音区域(“甜点”范围)大,可重发较高频率的声信号,系统声像稳定性较好。重发时,可根据重发信号频率来确定使系统达到最佳效果的扬声器布置方案。该系统将在室内声场模拟、多媒体计算机、家庭影院等方面具有广阔的应用前景。 |
| 英文摘要: |
| The sound fields created by a sound reproduction systems with three loudspeakers at listener's position are analyzed. It was proved that the listener's area (sweet spot) created by the system was large. This system can also reproduce higher frequency sound signal. At the same time the stability of sound-image is also better. The optimum loudspeaker arrangement will be decided according to the frequency of reproduced sound signal. This system has great prospects for the room acoustics simulation, multimedia computer system, and family cinema. |
