目的 探讨不同起始压和不同压力变化速率对静态声顺值的影响 ;方法 采用 - 6 0 0～ + 40 0daPa起始压 ,每 5 0daPa为一间隔 ,压力变化速率设置为 5 0 ,10 0 ,2 0 0 ,40 0daPa/s ,对 19名测试对象进行静态声顺值的测试 ;结果 在不同起始压条件下测得静态声顺值呈“V”型分布 ,压力变化速率的变化和所得静态声顺值为正相关关系 ;结论 起始压和压力变化速率参数设置改变对静态声顺值有影响 ,随着压力变化速率的增大 ,静态声顺峰值也增大
Objective To investigate the influence of different initial pressures and different pressure rates on the static acoustic compliance. The method uses a pressure of -600 ~ +40 0 daPa, an interval of 50 daPa, and a rate of pressure change of 50% , 20 0, 40 daDa / s. Nineteen test objects were tested for their static acoustic compliance. Results The static acoustic compliance was measured at different initial pressures with a “V” distribution and a change in pressure change rate The obtained static acoustic compliance is a positive correlation. Conclusion The change of initial pressure and pressure changing rate parameters have an impact on the static acoustic compliance. As the rate of pressure change increases, the static acoustic compliance peak also increases
