Hello,
I want to verify if it is true that ultrasound is effective against the varroa mite, currently the worst enemy of bees, which kills the hive in about two years if it is not treated with chemicals. I want to build an ultrasound source for that purpose.
I have a signal source like this
Now I need an amplifier and a speaker or tweeter. And a power source.
The system should work for about 30 days. You have to optimize consumption, so you do not have to use very large batteries.
My doubts are these:
- what power (watts) must the amplifier have to obtain 90 dB to 30cm in a closed enclosure such as the hive?
- What speaker would be suitable?
My bees appreciate your suggestions
