| 中文摘要: |
| 完全扩散声场中的总声压级计算公式是假设混响声能在厅堂中的分市各处相等，与接收点的位置无关．实测发现该公式的计算值们高，特别当接收点在临界距离以外时．本文提出了一个总声压级计算的修正公式，它与实测及计算机模拟的值符合较好． |
| 英文摘要: |
| The classical expression for the total sound level distribution in an auditorium over-estimates the reverberant energy, which is assumed to be a constant to all receiving points beyond the critical distance in the auditorium. It was found that the predicted values have wide divergence compared with the field measurements, especially when the receivers are far away from the sound source. A revised expression is presented in this paper and the predicted vaues quite agree with the measured and the computer simulated results as well. |
