测事测了个SCAN SPEAKER 9700

哈！上图！

测事测了个SCAN SPEAKER 9700

曲线也受到了一点环境噪音的影响呀,最近声卡工作不正常.不知为何.信噪比不理想了.现在家里超热.活像在桑拿房.有机会换个声卡玩玩.现在用的是黑金卡农.

好象测得非常不错哦，和官方图的走向非常接近

我的9900也快开测了。。。

对了，楼主用的什么声卡什么mic？

分别为白噪MLS、选通正弦波扫频、对数正弦波扫频。

第一个图中频响受到了障板衍射效应的影响产生了小峰谷。而这回采用近场的办法从测了一遍。9700曲线还真是不错。不枉人卖那么多钱呀！

以下是引用梦游在2005-5-17 8:35:00的发言：
频率下限比9500低了很多。不过从曲线看，障板衍射效应造成的峰谷比较明显了一些

老瓜壳

1图和2图的频响接近，但相位线却差别很大。还望维大给点分析：讲讲两种软件的测试区别。

我都论了好几次搞不出来这曲线呢

楼上两位估计都是考古系毕业的吧 ......这么好的帖子怎么就沉了呢，偶也参与一下考古 ，不知道测量设备是论坛出的测量套件么？准确度应该不错，9700看起来应该还是值那个价的

手谈目眩

维版，你的频响和相位线好清晰，为什么我的测试图会像过山车呢？


现在，跟着维版的脚印，开始25000里的折腾。
