It’s on a crowd-funding site, Indiegogo - https://www.indiegogo.com/projects/varroa-killer-sound#/ <https://www.indiegogo.com/projects/varroa-killer-sound#/>. Scroll down for the English version. It seems that it’s a German commercial honey operator (Kruger) but they have an apiary in Sardinia (Italy).

As tempted as I’m right now to get myself a late Christmas present, this little tidbit is giving me a pause:

The frequency of  14.500 – 15.000 Hz with 90 Dezibel is audible for people with a good sense of hearing, especially children! Outside the hive its just 30 Dezibel. Beekeepers, who are able to hear this frequency should use earplugs while working on the bees with the "Varroa-Killer-Sound"

With so many stories about noise assaulting our ears, do I really want to find out whether I have a good sense of hearing? Also, while it might be Ok in an isolated apiary, those with beehives near neighbors might want to also pause...
