Ultrasonic sound range?

a numerical sound range is not listed, a range of low, medium and high are the designations on the unit with a pattern option for rodents or insects.

I own restaurant - had big problem with rodents - Solved - at night when we leave , we turn it on loud setting - it's very loud and annoying ( has three levels - 1st not audible to humans , 2nd ok noise - high pitch 3; very loud - annoying ) Not sure what's the range - but it's very effective - I have one now at home and one in storage room. I m very happy Loud when turned on loud settings ( for rodents )

I usually have the sound source about 6 feet away. It all depends on the volume. As for following the music it's decent. For example if it's a slow song they blink and change colors slowly. If it's a fast song the respond accordingly. The more prominent the bass the better they react. You will not be disappointed with these. I wish I had purchased more sets has they have many uses.

It might be a little more than 40 ft. Both of my sensors are in the 50-60 ft range from one of the chimes and in the 40 ft range from the other. It probably depends on what is between the sensor and the chime as well.

You won't hear it unless you're within 10 - 15 feet. Also depends on how full it is.

10-20 feet. The range is pretty good on this device. Just don't have a wall in between your phone/device and these speakers because the frequency may cut here and there. Besides that, it has great sound quality and it can get pretty loud.

I have no way of measuring the sound. I run the unit on high about 3 feet from my bed when I sleep. Have no problem with the noise.

The warning beep will sound anywhere from less than two feet to about 10 or 12 feet. You can adjust it yourself with the range adjustment knob that the kick comes with.

42 dBA at one foot away. That's similar to a deskside computer with fans at medium speed. It doesn't interfere with listening to speech and music on an iPhone speaker.

I never tested to see how loud it could get, but the louder i made it go, the worse it sounded. you should be able to hear it withinn 10-20 ft. w/o any issues; you just might not like what you hear. I purchased it for music; sports or news may be OK.

I don't have a range for you, but if your going to be using another electronic device or cooking something in a nearby microwave ...it will distort the sound and make it impossible to obtain clear audio!

I'm guessing it's in the range of 75-100 feet but is truly a joke in terms of diameter of the speaker wire. At the very least this is one area where you'll want to upgrade to a larger gauge of speaker wire. Other than that for an entry level system I'm thrilled with it.

Consider that you are polishing metal so its going to make some noise I can hear mine in the garage from about 30'. My sonic solution cleaner is very quite.

Hey. I really wish I could help you but I have no idea on an ACCURATE frequency range. I remember reading some stuff when I bought them, but that was only what the company or Amazon claimed about them. I don't know if there's a way to measure, but I don't have any tools for that kind of thing.
