| 中文摘要: |
| 本文首先说明声场控制的各种方法,然后对卷积法、混响室反馈法和混响器反馈法进行了实验研究,并着重阐述卷积法声场控制的实验系统。实验结果表明,卷积法可使中频混响时间提高3倍以上,效果良好。 |
| 英文摘要: |
| In this paper,first the various methods of sound field control are expounded,then the experimental work has been tried on the methods of convolution,o freverberation room feedback and of rever berat or feedback.The emphasis is made on the explanation of the experimental system,which is controlled by the convo lution method.The experimental results show that this method canincrease the rever beration time at midfrequency by more than three times with good effects. |
