For the decibel reader, you might want to remove the foam screen cap. Thats there to prevent wind screen noise, but as you are indoors, would be entirely unnecessary, and at the range of sound you are recording, that foam screen cap may very well perform as an acoustic absorber. Also dB's are a non linear scale, 20 dB's is an extraordinary amount of energy, even an increase of 1 dB in the upper level is quite a significant and almost unsafe amount of energy. Also another thing is that High frequency noises are **extremely** directional. If your sensor is place even a little off access, you will get a significant decrease in decibel reading, this is part of the secret of how directional mics work to begin with.... which is another reason why emitters are ineffective. This speaks volumes that rodents will straight up eat within a choir of them. Good on you for exposing the fallacious industry of these sonic emitters.

If you look close, you can see that the mouse has ear plugs on.

It makes me so angry that these things are still being sold and they don’t work. Where are the consumer protection agencies banning these devices and suing for false clams.

Actually, the Federal Trade Commission did send out warnings to over 60 manufacturers in 2001, and even sued one for ignoring their warning. The problem is that these do work, in theory. I mean, wouldn't you avoid irritating noise? The problem is that the pests soon become acclimated and they lose their effectiveness. And future generations are not affected at all due to Natural Selection. But that's just like any pesticide. So the FTC can't ban them outright, and only tell them not to make outrageous claims. www.nachi.org/ultrasonic-pest-repellers.htm

Hey Amigo thanks for the effort you put into this. Most of what I read says that these ultrasonic devices don't provide much assistance in repelling mice for various reasons--placement, gradual acclimation to the sound produced, etc. I wonder though how accurately a standard db meter can detect volume( or more correctly sound pressure level-SPL). Decibel meters seem to be aimed at measuring the SPL of frequencies that humans can hear (20hz to 20,000 hz) to aid in the prevention damage to human hearing in noisy environments. Measuring the sound pressure level of frequencies beyond that range( so called ultrasonic) probably requires a different instrument. Perhaps the one repellent device that seemed to be "working" was emitting a frequency that the meter could detect. No criticism intended here just some fun musing. The bottom line is the little buggers are winning.

This doesn't change the conclusion, but the sound meter almost certainly has limited bandwith, so it wouldn't pick up much (if anything) at those frequencies. I'd guess the one it does give a reading for emitts EM noise. Look at the data sheet for it, it should have a frequency range specified. Outside that it likely drops off steeply.

You don't subtract the ambient level from the reading to determine the decibel level. As long as the noise source is above the ambient level that is the true decibel reading. If it is below the ambient level, you cannot measure it.

You can 'expect' the pest repellerto work well if it has the ability to change the frequency of sounds that it emits. This is because mice and rodents are not used to changing frequencies, and therefore might get irritated due to it. The high frequency sounddoes not work if it encounters a solid obstacle in its way...

I received it and plugged it in at the worst point of infection where they make the most contact with me. Their numbers were greatly reduced and they didn’t come too close to me. I had to use it at the highest setting which was audible to me and annoying af to my dog but it worked. Finally the spray arrived and I was able to keep them at bay out if my apartment until an exterminator took care of the whole building.

dB is a logarithmic scale, so in order to subtract the ambient noise you would first have to convert into sound power, then subtract and then convert it back to dB. But for the dB's you measured the end result should be almost identical to the original measurement (every 6dB the power drops by a factor 1/2, so for a 30dB difference means a factor 1/64 difference which translates to only a 0.1 dB reduction so negligible).

Thank you for video. It is good that you use a sound meter to evaluate DB level of each device. As far as I know, a quite room is appr 20 DBs. Conversation is 45 DBs. Busy traffic noise is 70 DBs. So anything below 70 will be ok for humans. However, since rats can normally hear ultrasound in its lifetime, so an additional amount of ultrasound produced from small device would be neglected. Anyhow I have been using this device for 2 weeks, I observed the different. It works under my carport. By the way, in your tests those with no signal or 5 DB should be broken circuit board.

The problem is that decibels don't measure frequency. Decibels are used to measure volume. FREQUENCY measure the number of times a sound wave passes a fixed point. Sound comes in waves and the number of times each second a new wave passes a point is the FREQUENCY of the sound.

If they are ultra sonic that would mean they are super high frequency right? Based on info for stereo systems.... low frequency is referred to as low on no directional, while high frequency is directional. So I wonder how effective ultra sonic emissions are if the are uni directional. Meaning if the sounds is dispersed almost straight out of the emitter, do they have to stand directly in the path to be deterred by it?

Well, even if the sound was annoying it was still worth enduring it for a free meal.

Your device cant check over 12 kHz soynd frequency. On the other hand the ultrasonic repeller frequency is more than 20KHz . So you wrong . You cant check ultrasonic with sound meter tester.

to test simply install a spectrum analizer app to your gadgets, it shows the frequency and the intinsity, sonic output of the device

Found the same thing with big speakers. Just get a sound file or play a 20kHz KZread video really loudly. Works better (I can hear them squeak and run after about 60 secs) and costs nothing. It's not a permanent fix but it seems to have an effect.

Nice and informative, and although I believe the units have little effect, the test method used is not really done properly. 1- First of all, the frequency range of the SPL is selected to reflect our hearing range, so the meter might not be within range of the devices, and one should ascertain that it can actually measure in the appropriate range, Sub-sonic or ultrasonic. The unit shown is many for human range. 2- Most SPL meters have a range from 20Hz to 20kHz, and have weightings, i.e. roll-off filters that limit the bandwidth, known as A-B-or C weighted readings. 3- The sound emitted by each device should all be measured at the same distance. At the distance shown, there is a massive difference even at a half-inch, likely around 10-20 dB each time you even marginally move the microphone. Think of how headphones change in sound pressure when you even move them a fraction from your ears. 4- room noise is never deducted from the reading, The device outputs the reading you see. Room noise is irrelevant to the sound pressure level of the device you are measuring, except if the output is below residual room noise. So to be honest, this test really didn't evaluate functionality, other than establish that either the mouse was deaf, or no longer cared and was really hungry. The mouse learned that the sound was just annoying, and not a threat. Sorry but you can't always believe what you see on the internet. The old sound engineer....

1. Keith Vanderkley has rightly pointed out. I am adding few lines on redundancy of Sound Level Meter (SLM) test conducted. The pest repellers generate ultrasonic range of frequencies (usually, 20 kHz-158 kHz - audible by pests), which is higher than human hearing range (20 Hz to 20 kHz). Moreover, the SLM used looks like an ordinary one, which may not responsive for frequencies more than 8 kHz or 16 kHz. Metaspencer may check the specs of SLM and verify its actual range of frequency response. Interestingly, a pest repeller must be faulty if someone can detect any sound (either by physical hearing or with an ordinary SLM), as that repeller is not supposed to generate any frequency below 20 kHz. In that case, the device will be harmful for human being, since prolonged exposure to a noise within audible frequency will create annoyance, distraction and other physio-psychological disorders. 2. Effectiveness of any repeller can be assessed by practical application. Of course, any influencing factors (as also mentioned by Keith Vanderkley) must be excluded, which a bias the effect.

How about for bugs, like spiders, roaches, ants, fly's and mosquitos? I took these to the Philippines. And using a 500 watt inverter for each. I placed 1 in each room and 2 in the kitchen. I didn't see roaches any longer. They were behind a baseboard in the kitchen. A mouse came to my home in a cargo box I had shipped from the U.S. I used a glue trap and that caught the mouse in one day! Mice in the Philippines look lots skinnier and different than U.S. mice. I held the glue trap up close to examine the mouse before trashing it. The eyes looked black and the surrounding part looked like it was dripping white. No kidding, looked like someone painted the eyes and the eyes were watery or melting. Very odd and gross to a certain extent. But no bugs once I turned the emitters on at night.

Yes, I have a perfect and complete solution for you. It doesn’t work on mice unfortunately, but if your problem is roaches, it absolutely works on them. And if you have pets, it’s great because it doesn’t harm them. It’s called Diatomaceous Earth. It’s cheap, it’s amazing, and it works like a charm. I moved into an apartment building once that turned out to be infested with roaches. Horrible. Asked the landlord to pay for spraying (even though I didn’t really want to, because I don’t think spraying hormone disrupters, etc, is good for us either, especially women). But I got it done anyway, and it did nothing. Finally learned about diatomaceous earth. It’s so cheap, I gave a cup to all my neighbors. No more roaches within 3-5 days.

ARE YOU REVIEWING THE DECIBELS OR THE EFFECTIVENESS REPELING MOUSE?

One thing you should know.....1 noise making 60 db and add another device making 60db does not equal 120 db. It would be 60 db. So your first device was actually putting out the registered amount. The higher number only cancels the lower so if it were dead quiet the readings would still be the same. just sayin

This made me laugh 😂 it’s clearly his stomach is taking over his ears 😅😅

Can I ask if your meter is omni directional. It seems as if you were getting a better signal when it was pointed at the device.

IF ITS A FLY SPRAY OR OTHER INSECT SPRAY THAT WOULD PROBABLY WORK BETTER. IF YOU SPRAYED DIRECTLY ON A MOUSE WITH INSECT SPRAY, IT WOULD KILL THE MOUSE. WILD MICE TO INVADE OUR HOMES ARE THE BIGGEST PESTS GOING.

If you get a cat, then make sure the cat knows how to hunt mice. Get a kitten raised by mouser barn cats would be optimal.

Q. The one we just bought says it must be plugged x inches above the floor. It is like over 30”! And it says it must be plugged into a vertical outlet, upright… not a sideways outlet. We’re in a small apt, and most of the outlets are only a foot above the floor. Can anyone explain why it would not be all right to plug it into an outlet that is only a foot above ground? Thanks.

@@metaspencer Thank you for your quick, savvy response. Had we seen this video, we probably would not have bought them. Thus far, the only thing that had worked is a live catch metal cage with a trigger. Mouse ventures in, finds treats on platform, and the door shuts. Then i take them outside to release them. Sigh. I waa hoping the sound deterrent would work.

aren't those decibel testers used for subsonic sounds? how is it going to test ultrasonic.

I installed an ultrasonic pest repellent in the kitchen and discovered the roaches actually congregated around the darn thing like it had candy on it. Weird. Save your money.

That will make it easier to kill them.

Just to be clear, your math on the dB was not 100% correct. It's not added to the ambient sound... In this case, your room was abut 35 dB (noise floor) and you had a device produce 75 dB. It's not additive i.e. 75-35 = 40, the device produced 75. If your noise floor was 10 dB, you still would have read 75 on the meter.

Is this a fair test? The ultrasonic wave could be of a higher range (e.g. 25KHz to 70KHz), whereas the decibel meter could be of a lower range (e.g. 8KHz to 31KHz). Decibel meters are typically designed for bionic waves that humans can hear (e.g. 10KHz-25KHz).

If it's just a matter of Decibel Levels, get yourself a Pantera CD (I recommend "Reinvention of Steel") put it in your Boom Box and play it all night. that should get rid of the mice...or you'll have a mice mosh pit

Well I had a mouse coming into my kitchen. I did a lot of research online , and ultra sonic pest repellents do work. First the brand matters. Also did you read the instructions? Do not use with an extension cord. Must plug into wall. I downloaded a app to my phone and it worked great til I could get a three pack at Walmart.

With mine it says when you plug it in a wall it has to be horizontal. In other words with the two prongs side by side instead of on top of each other. Then it has to be at least three feet off the floor. I had to use mutli outlets to hang to get this to work. So far the front one works. I'm still figuring out the back one. But I also use a good inside/outside pest spray.

"Manufacturers of ultrasonic pest repellers make claims that may be unsupported by scientific testing. In fact, more than 60 companies received warning letters from the FTC in 2001 stating that “efficacy claims about those products must be supported by scientific evidence." Two years later, one company was sued by the FTC for violating its warning." [INTERNACHI]

2:55 You cannot add decibels by simple arithmetic addition, because they are logarithms. If you have two sound sources, each producing, say, 50dB at a distance of 1 meter, turning them both on simultaneously will double the power, and the doubling of power in decibels is 3dB, so the resulting sound intensity is 53dB, not 100dB, which you would get by adding the numbers together.
