POWERFUL EXTERNAL SOUND 超強力的外聲

You need good External and Internal sounds to lure Swiftlets to fly into your farms to build nests.  Your Swiftlet sounds have to be extraordinary, unique and stand out among all the sounds played by other Swiftlet farms.

您需要良好的外聲和內聲來吸引燕子飛進你的燕屋農場作燕窩。你的燕聲聽起來必須要非同尋常、 獨特和與其他燕屋所播出來的燕聲中脫穎而出。

It is not impossible to have a sound that could do that. The sound that I am referring to is 3 Birds King

這不是不可能的，的確有這種聲音可以這樣做。我所指的聲音是 3 Birds King.

All it needs is a good tuned sound frequency coupled with good Amplifiers that could channel out all those irresistible luring sound.

它需要的是，良好的聲音訊率調整加上好的放大器，發出那些不可抗拒的引誘聲音。

If your Swiftlet farms are unable to lure large numbers of birds to come and play then you can forget about them building nests.

如果您的燕屋農場是無法吸引大量的燕子來玩，那麼你別期望它們會做燕窩。

( Note: Best played with Hi-Nest B-52 Amplifier and Hi-Nest GS-18 Piezo Tweeter.)

（注： 最佳組合是與Hi-Nest B-52 放大器和Hi-Nest GS 18 壓電高音喇叭.)
