为什么用中文书写？ Why we are writting in Chinese?

因为马来西亚90+%的燕屋业者都是华人，所以我们决定暂时以华文为主要的媒介语，如果需要其它语言的翻译或更详细的解释，我们也一样可以提供。

We are writing in Chinese because most of the swiftlet farmers in Malaysia are Chinese. If you have difficulty in understanding, or you need further explanations in other languages, please feel free to ask for translation.

扬声器的编排和声音


我从柔佛回来后，有不少读者问我，为什么会这样？3个月了还没有看到任何的燕窝。
大家请看以上的图片，每一个颜色代表不同方向扬声器所发出的声音。

大家如果了解声音的音波，相同频率的音波会互相抵消。红色的声音和青色互相抵消，橙色的和粉红色的互相抵消。同样的频率，同样的声音一起抵消，燕子所听到的声音会是非常的渺小的。

如果所有的扬声器都是用互相抵消的方式安装呢？

    if right and left tweeters not playing the same sound, then the sound will not able to cancel each others. Just like Home Theater system.
