I disagree. Those tests were of 20-70 kHz, not 45-67 Hz. I've

The speakers don't work very well at the frequency range

There is an Article that says that the experiments done with low and
high frecuencies failed:
Thanks, Chris, James, Caryl
It's true emulating a dragon fly's wing beat maybe a bit simplistic
or ineffective

Let's put this to a test!
With all the flooding we are having in Montana this summer the clouds of

The speakers don't work very well at the frequency range specified by
that article for mosquito repelling; 45 Hz to 67 Hz.
The article fails to mention how much sound is needed; e.g. in dBm. It
gives a subjective measure only.
Other articles on the site mention secrets of ancient geometry and
