Absolutely brilliant and well overdue!
It's also good news for #cats #dogs #rodents and other creatures whose hearing is sensitive well above human frequencies (assuming this device also suppresses > 20kHz).

Now, more importantly, perhaps someone in Johns Hopkins' psychology department can find a cure for those suffering from leaf-phobia.
@spacemagick I agree. That would finesse the entire problem and save money, time, and effort.
