主题：Tone burst test discussing

请问一般作Tone burst test的电压Vp-p和所用Track依什么规则定？

我用的ALMA的EIA-426B测试碟

测试的目的：

使用一种加速寿命的方法测试一个单元在或者是接近他的最大位移以确保这个单元符合系统的需求超越系统的寿命；当遭遇音乐有一个高的振幅因数时，这种脉冲测试是设计来重复这个位移和机械应力；而不是设计用来测试喇叭的热能处理；相对于用于功率处理它是典型地运行在一个高峰值电压水平， 但这种信号是建立在避免磁路过热影响这样的一种方式的基础上。                                      

原文如下，供比对参考：

To test a transducer at or near its maximum excursion with an accelerated lifetime method to insure the transducer meets the requirements of the system over the system’s lifetime. The tone-burst test is designed to replicate the excursion and mechanical stress encountered with music having a high crest factor.  It is not designed to test the thermal power handling of the speaker.  It is typically run at a significantly higher peak voltage level than that used for power handling, but the signal is structured in such a way as to avoid significant heating of the motor structure.

 不过说真的，这种测试方法对测试喇叭中心胶强度和边与胴体粘接强度倒不失为一个好方法。
