测量音箱在房间内的频响不得不知道的一组测试频率
本帖最后由 fengxi 于 2015-4-25 17:40 编辑如果要测试音箱在房间的表现我想最简单的办法就是用声压计了,那么该用什么频率去测试呢?通常建议1/3倍频程分开,也就是下列数据:
10.0 hz
12.5 hz
16.0 hz
20.0 hz
25.0 hz
31.5 hz
40.0 hz
50.0 hz
63.0 hz
80.0 hz
100.0 hz
125.0 hz
160.0 hz
200.0 hz
250.0 hz
315.0 hz
400.0 hz
500.0 hz
630.0 hz
800.0 hz
1.00 khz
1.25 khz
1.60 khz
2.00 khz
2.50 khz
3.15 khz
4.00 khz
5.00 khz
6.30 khz
8.00 khz
10.0 khz
12.5 khz
16.0 khz
20.0 khz 别人都i5i7了,你还在用手摇的。 pcello 发表于 2015-4-25 09:25

成本差远了,又不是专业,当然选择低成本方案。 fengxi 发表于 2015-4-25 10:09

如果能测到上面的频率,声压计的价钱可以买到不错屿音箱了 jingship 发表于 2015-4-25 10:54

一般情况下10到25Hz不测也行,大多数音箱达不到那个频响,剩下的缺四个数字,那就没办法了,廉价的声压计能测30~8K。 现在专业测试仪器不贵,谁不是拿着智能手机?有智能手机,声压,频率全测了。 fengxi 发表于 2015-4-25 10:59

一般万元以下的能保证精度的是300到8K,你看下其说明书 lf00516 发表于 2015-4-25 14:32

智能手机精度不够 楼主的频率间隔是三分之一倍频程好不好
六分之一倍频程还得增加一倍的频点 jingship 发表于 2015-4-25 15:22

廉价的型号AR844,说明书是这样写的:

你是对的,我少放了频率点,偷懒了 你看一下测量套件的频率分布吧:

给个公式就好了啊,再加前面几个数字就够了吧。
我估计,真拿这个表格去测量的人几乎没有吧。

这是LSPCAD测量的导出数据,不是谁编的。整个测试从点击测试按钮到数据出来就不到一秒,这就是工具的重要性。 pcello 发表于 2015-4-26 00:00

不好意思,没留意,还以为只是频点呢,是实测数据啊。(这就是数据多了的缺点)
这些数据直接显示成一个曲线多好?详细的数据一般根本用不上。 cdzx11 发表于 2015-4-26 00:59

本来是曲线的,导出来是TXT格式。
