Women and children often hear higher pitched noises, and some people hear at even higher ends of the spectrum, than the average woman or child. Like me. Now my hearing has been tested and I've been told by doctors that my hearing goes beyond the normal range of human ability, but I don't believe I'm the only person in the world who can hear high pitches. My neighbor got one of those and I thought I was going to go nuts. They couldn't hear it. I on the other hand would have run away if I was a rodent but I lived there and worked at home so was tortured with that noise for weeks until I could get them to disable it.
Because I could hear this thing, even on the lowest setting that humans supposedly weren't supposed to be able to hear (the thing even said some women and kids may hear it on the high setting), I don't trust that pets of any kind won't hear it (I'm sure they have individual variation too)...or humans either.
Sorry for the rant. It was horrible and stressful experience and I wouldn't want any person or pet to go through what I did.
Those sonic pest deterrents are a creation of beezlebub.
