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 crystal harmonizers. This really doesn't impress me. Is there any evidence base for repelling mosquitos using low frequency sound? Is there any evidence that enough of the population of mosquitos is repelled? All it takes is for one strain to not be repelled and it will breed up. -- James Cameron http://quozl.linux.org.au/ _______________________________________________ IAEP -- It's An Education Project (not a laptop project!)
