Can humans hear the sound of this or just the animals

The frequency can be varied. I was able to adjust the frequency of the output low enough that I could hear it. I use the repeller at a higher frequency that I cannot hear. The highest frequency that one can hear decreases with age.

It has an audible high pitched hum. Very annoying if you are too close to it or if you have sensitive hearing.

If you are waering them no, they can´t. If you are not wearing them and they are really close to you they might hear it.

Same thing with our dogs. I wonder if they just adapt to it and bark anyway. I guess the noise they hear is not strong enough to be a deterrent. It might work with some dogs.

I'm not sure-depends on how sensitive your dog is and how close she is to you. My Lab can hear it through the walls and across the yard and will run to her dog house.

If you can't hear it then it's not electrically working. If you are expecting to turn it on and for everything to stay out of Tue year, there's no such product. Animals won't hang around areas in discomfort, that's really what this product provides.

No , the manufacturer promises the frequencies used are different than those that dogs and cats hear, so it will not harm them nor can they hear it.

I have no dog, but the device even with the ultrasound option selected emits a sound that can be hear by humans and is kind of uncomfortable if you are close to the device. Anyway I believe you should ask the seller, they have a wonderful customer service.

Yes, unfortunately humans can hear them. We have a toggle switch installed inside the car and only activate them - we have 2 - when we are in areas where deer are present. My husband brought the wires into the console via the door panel and gorilla tape. So far that works great and is holding up. Good luck!

It sounds like air blowing (not loud). You can set the pitch. Our dog clearly hears it, but it's not distracting to people. Our dog is really trained to it, and comes promptly (we don't have little ones, so I don't have actual data on this, but adults don't here it). I will try it when my grand kids are here at Christmas (ages 4 & 7). We are very happy with it (have 2).

Yes however, my neighbor's keep covering it because they can hear every setting volume across the street. Its not effective on the animals anyway. Only neighbor's.

the dog may not hear so well due to breed. dogs over the years have been bread to do different thing for man. hunt by smell sight or sound. my unit works ok but there is a pack of small dogs next door.they do stop barking after a min or so. I wish my neighbors would just move I can only hope. Joe

When I get really close to our dog, I can hear a slight sound, it does not mean it is faulty.

Probably. My dogs don't like sounds of any kind. This device only stops them because they can't figure out where it comes from.

Yes. It's not silent but if anyone is around you, they probably wouldn't know what the sound even is.

No. They must be in a place where the air can flow through it to create the sound to which the animalsrespond. I put mine on the front bumper of my truck and on the bottom of the grill of my car.

I would think so, they muffle conversations, music and other noise but you can still hear them. You will still be able to hear the dogs but it won't be as loud. I used these on my motorcycle and they weren't good for constant wind bombardment, but they were great for a show/concert I went to.
