"Pak Harry what will be the best volume that we need to use for the "Last Tango" gadget?"
Remember the "Last Tango" is something very effective to pull those wild birds into your BH. I invented is about three months ago, where I will install a separate set of power tweeters (about 10 to 14 pieces) around the entrance hole areas (for top entries) and connect to a timer with cable connected to the external sound amplifier.
To realize the effectiveness you need to push the volume higher than the standard external sound volume and played only during those peak hours.
What volume should it be tuned to?
My best advise to those who have the system is to observe the behaviour of those swiftlet when they passed by your BH.
You need to do the observation and have your helper to tune the volume to the level when the birds flying home will start to be affected by your external sound.
Talk to your helper with your mobile phone and observe the bird's behaviour.
The moment they started to jump into your open roof or your monkey house opening, that is the best volume using the selected external sound.
You might need to re choose the volume when you have decided to change the external sound.
Once you have the right volume, stick a tape on the volume control area and put a marking.
In this way you will know the right volume during your visit or if you accidently touched the volume knob.
I hope this short clarification gives you a better idea on the volume to be used for your BH "Last Tango" sound system.
