Ultrasonic Sound


“James is it Ok to use the Ultrasonic Sound as my friends encouraged me to use it”.



This is the Sms I received this morning. It is not new, I often receive question like this and they want to know about the Ultrasonic sound which is available in the market.



What should I say? To be sincere or …..Often sincerity would affect others people businesses.



This is not new I guess most have already known this for long time. Sound is frequency and frequency could be tuned and adjusted. It’s all depended on how the equipments being set during the manufacturing or assembling process.



The only worry that I had with the ultrasonic sound is that, has it been really tuned to the frequency that suit the Swiftlet. I mean the particular type of swiftlet which


is A.fuchipugus fuchipugus.



If the ultrasonic sound (frequency) is not tuned to suit the Swiftlet then it would do more harm than good. I doubted that the ultra sonic sound equipments available in the market are for the purpose of Swiftlet farming.



Basically it was brought in for other purposes and since there are people complaining about the loudness and Swiftlet sound pollution therefore those who knew about this capitalize on this niche business.



In fact Ultrasonic sound is or relating to acoustic frequencies above the range audible to the human ear, or above approximately 20,000 hertz. As for the swiftlet their echolocation is below this range therefore we could hear them.



Will it works….it is a big question. Many years ago if I could remember perhaps 4-5years ago the ultrasonic sound is already in the market. A buddy of mine took a set and tried out at a prime bird’s zone. The result, not a single birds came. He switched back to normal Amp with the same sound and within minute hundred of birds swapping above the tweeters.



He has not only tested it out on one particular area buy many different areas all over country as he has many Bhs and the results were the same.



Whether the ultrasonic sound works or not is not so important. The worry is that if the Ultrasonic equipment use is tuned wrongly it would cause disastrous effect to Bh.



It may produce some frequency that disliked by birds. In fact pest control companies for birds like Pigeon use sound frequency to chase away birds, because in some countries trapping and killing them is prohibited.



Imagine if you have bought a set of such Ultrasonic equipment and use in your Bh what would happen?



Good Swiftlet farming all
