My answer is no! Not too loud. I think I had mentioned this before in my previous article if I am not mistaken. Anyway my advice is not to blast the sound too loud. Swiftlet won’t be attracted to the loudness of the sound it is the quality and the contents of the sound that counts.
It is similar to human, if a lousy song is being played no matter how loud it is you will hate it and complain about it. If a top ten hit song is being played no matter how loud it is you will tap your feet and may sing along.
So the quality counts not the volume. Having good tweeters and Amp wouldn’t serve any purposes if the quality of sound is not good. Good quality sound means not only it is clear and sharp its also must contain good mix of attractive swiftlet chirping sound. If its only clear and sharp but the chirping sound is not attractive then it is useless too.
(At last on 1st. October 2007, the swiftlets started coming into the farm. We had waited with much anxiety, watching the birds circling and passing by but only a few entered the farm. Thinking that the farm is an standalone farm and far away from other farms, we set the calling sound louder than normal but it seems to backfire. Only after tuning the sound to a lower volume on the evening of 30th September 2007 that we saw the result.
Picture of the completed farm. It is a standalone farm on agriculture land and quite far from the nearest house (about 300 feet away).
The above picture is from my friend's blog "Tirok". I am sure many have known this. In fact he experienced this way back in 2007. So too loud of a sound would cause harm than good.
I am not talking about who or where you got or bought it from most important what sound is in the it.
Some even ask me shouldn’t they test it first which sound is effective before they purchase it. You could do that if you are inexperience in sound.
If you have knowledge in Swiftlet sound or know the language of Swiftlet the moment you hear the sound you would have known whether it will attract birds or otherwise.
So remember the content in the sound not the volume neither who nor where you bought if from.
Good farming All!
