The peak sound level is independent of the detonation frequency. Impulse sound pressure level and sound power level and sound power increase along with the increasing of detonation frequency. 峰值声压级与爆震频率无关,脉冲声压级、声功率级、声功率随爆震频率的提高而提高。
The regression analyses of the peak sound pressure on shuttle and picker of silk loom and the discussion on its reduction 丝织机梭子、皮结峰值声压的回归分析及其降低的探讨
The Research on Anticipated Measurement of Total Peak Sound Pressure Level by the Light Arms 轻武器噪声峰值总声压级预测方法的研究
Due to the large transient peak sound pressure during an extremely short period, shock noise can cause lots of harms. And corresponding safety criterions about shock noise have been composed all over the world. 冲击噪声极大的瞬态的声压峰值和极短的持续时间决定了其极大的危害性,世界各国经过试验都制定了相应的冲击噪声的安全标准。
Panel contribution analysis was made at those frequencies where peak values were found. Then panels which had a large contribution to the sound pressure of focused points could be found out in order to set target for the structural optimization. 4. 针对峰值频段,对车内关注点处声压进行了面板贡献度分析,找出对关注点处声压贡献较大的板件,为结构优化制定目标。
