content: Hello everyone. Sorry to bother you but don't know where I might find help with this issue. This sounds really weird but I put up a fence to keep the neighbors dogs from eating my chickens. He then came over an was yelling that fences are ugly. Now when I'm outside or in my shop or house he is shooting something at me that pops in my ears and then my ears rings for hours. Whatever it is is portable. All I hear on my end is a click and then sounds like something pops in my ears. Almost feels like something touching you. Then my ears ring for hours. What ever it is shoots long distance. At least 150 to 200' feet. I've looked up dog deterrent but I don't think that s what it is. Any Ideas?

content: Jeez... First thing is to try to record that event. Then someone might help more. What you describe is weird. There is of course such thing as sonic weapons, but they work small distance, cost huge money and almost for sure that your neighbour does not own one. Also it will not work through walls.Maybe he is using some toy or a special purpose gun which shoots little exploding pellets? Thats all what comes to my mind. But then you would feel the direction, and also it will not make ears "ring for hours".Record it and post.

content: Did you try to settle the dispute with your neighbour, before building the ugly fence? If that didn't work, you should have left the fence as it was and set up some kill traps designed to catch foxes and coyotes.I have no idea what it could be, perhaps some sort of microwave or ultrasoinc weapon? If so, it's certainly illegal to use it in this manner, as you're not posing any threat to him.Do ear protectors help? Other than that, there's not much you can do, other than contact the authorities, in the hope they can do something about it. I doubt you can legally do anything to retaliate.

content: Quote from: Zero999 on January 05, 2021, 03:54:24 pmAt least in my country it really helps if you collect some evidence yourself. In fact, without having any evidence some lazy officers might just come and leave without doing nothing and make you look like an idiot. Not always, but happens. So in such case I would record audio, take pictures, make videos, etc, then contact authorities.

content: Have you seen him setting anything up? Police have sonic weapons they use against demonstrators. I've seen pictures of them, but thankfully have never had one used on me, as far as I know.Whatever it is, since directed audio frequencies or RF may be involved, there must be a meter which could pick it up and document whatever it is. What I would doif you are 100% certain he is doing thisis figure out some way to catch him in the act.Ultrasonic sound and RF are two different things that would be measured by completely different kinds of equipment. I wouldn't invest a lot of money, I would only do that if a first attempt reveals that there is something being aimed at you.If he is aiming something at you with the intent to do you harm, that must be a crime.Ears ringing. This deserves serious looking into, because ears ring when blood brain barrier is disrupted, (at least thats my theory) and I suspect that means you're likely to experience permanent cumulativehearingloss (if it is audio frequencies being directed against you for extended periods of time) or possibly worse if its powerful RF. (I think that's very very unlikely.) Hardware that's intended for crowd control if misused could likely cause permanent hearing damage. That's no joke.If you can prove it's there.Either way its not good. *Both audio and RF likely could cause a ringing in your ears* The ringing may be a secondary effect of ultrasonic sound, or some ototoxic, but non-auditory process, which is modulated by it but which also may be preventable by improving your glutathione status. (See below for more on that)Quote from: Zero999 on January 05, 2021, 03:54:24 pmMy gut feeling is that the authorities will just write you off as a nut unless they have some reason to believe you are credible. At the end of the day, among other things, you'd get credibility by hiring an environmental lab. But that will be expensive unless you know what you're looking for.Do you know any local police on a personal level? A good operative theory might be that your neighbor has somehow gotten a hold of one of these crowd control devices normally sold to cops, and is aiming it at you. You have every right to put a fence around your property, unless its prohibited in some way by your local laws. Some laws have height limits on fences.Maybe he is concerned about his pets?If I were you I would consider CCTV also, and a DVR.To measure ultrasonic sound you likely need a computer with an audio input whose sound card can sample above the standard 44-48 KHz. (92 KHz is fairly common) and you need a transducer with range that high.A piezo transducer may be able to help pick up and document ultrasound.A program called baudline does a good job of displaying the audio frequencies visually.For RF you likely need a field strength meter or spectrum analyzer with range in whatever putative frequency he is using. Find out what frequencies thesecrowd control"nonlethal"devices use.I think the audio frequency device is much more likely.They are almost certainly illegal to use by non law enforcement people unless they are literally in the middle of nowhere.---Which makes me want to ask the question, is there any way you can resolve this - even at this point?Especially if you live in a rural area, its better to have friends for neighbors than enemies.He sounds like a creepy person, but these days a lot of people are just stressed beyond belief by extraneous stuff.The more slack we try to give one another (within limits) the better.Keep also in mind that getting a credible official workup on the situation by a environmental lab that does forensic work could easily run you thousands of dollars. So make sure you have evidence (for yourself) that points in that direction before you hire somebody. Collect your first line evidence perhaps on video with a time date stamping, and perhaps a friend there, preferably somebody who has some heightened credibility in your community, who is unconnected to the situation who can act as a witness.-----Here is something I am personally curious about, that may be useful to know.Just for future reference, the evidence is pretty strong that NAC (see below) will help delay the hearing loss that comes with aging fairly well. The improvement in GSH (redox) status is good for all sorts of things. This might also prevent the ear ringing you describe which I know well. All sorts of things cause that ear ringing in me. Ive found NAC helps reduce or eliminate it more often than not.Often my ear ringing is caused by various household chemicals, VOCs, even some strong perfumes in lotions middle aged ladies seem to slather on. Big box stores often make me ill because of these low level smells. There is clearly a common mechanism involved which NAC helps fix.What is NAC?N-acetyl cysteine (NAC) - the most affordable amino acid precursor of glutathione in the body.Its possible, maybe even probable, that taking NAC when this is happening makes the ringing get better a few minutes later for a few hours? (but then it would get worse again when it wears off) You can spoon around a level teaspoon into some water and drink it, to get it into your bloodstream where it needs to be to prevent whatever damage may be occurring. As we get older, its a very good thing to take.(seehttps://academic.oup.com/jn/article/134/3/489/4688681?login=truefor a good overview of its function)However if you have "silver" (mercury amalgam) fillings. (dental restorations) that's NOT a good idea because it will pull mercury out of them. If you have silver fillings, fill a bunch of 000 capsules with it and take that instead.

content: I can hardly imagine RF beam causing such strong audible disturbanceswithoutburning the skin at the same time. Any high power microwave source will first of all cause noticable skin heating and possibly damage to eye cornea. Must be some sonic weapon. Very strange story.Edit: Just came to my mind. If this story is real it is possible that he is not shooting nothing, he is not using any "star wars" technology, he might be using some kind of poison to cause these effects to you. There are some well knownototoxins, which causetinnitus, which includes symptoms some of which fit your description.

content: Unless I could prove otherwise, I would assume the popping noise is the sonic boom from a projectile passing by. A gunshot. The 'click' could be the projectile impacting a tree where it would be unnoticed. Suppressors do a somewhat decent job of reducing the sound of the discharge. A small cartridge, like a .22 Short, might be very quiet. Apparently, an air rifle can cause a projectile to go supersonic and would be very quiet about doing it.In other words, I would take this very seriously and definitely report it to the cops. They're having a campaign right now to reduce gunfire. I would tell them of my assumptions. They may have a lot of interest in talking to your neighbor. Just a 'knock and talk' may end the hostilities.I don't have neighbors like that. We do have privacy fences and it's pretty much expected. We don't shoot at each other either!

If there is any chance he discharged a firearm at you, you should take this very seriously.Quote from: easttexasnewbie on January 05, 2021, 03:29:24 pmHave you seen this device, or any device? It likely cant be behind a fence, the slats of a fence would block most of it out. So its likely within your sight. Take a photo with the highest resolution you can.Look for something like a sound cannon.

content: How often does this happen, and where are you when it happens? Have you considered that your neighbor may not be doing this, but instead you have tinnitus? Tinnitus is more than just a constant high-pitched ringing in your ear -- it can also manifest as a sudden onset of loud ringing, and your ear feels/sounds as if it's plugged. After a minute or so, the ringing diminishes and your hearing returns to (almost) normal but with the ringing persisting at a much lower level. This can happen with no obvious triggering event.This happens to me several times a month, and (with no medical expertise) I assume it's one more inner ear hair cell dying, and that's one particular frequency I will never hear again except as a constant low-level ringing. The ringing can also be worsened by loud percussive noises (hammering, gunshots, etc.), stress, caffeine, aspirin, and no doubt many other factors. I blame this on my years of playing in a rock band, but there are probably many other potential reasons.

content: You need to have documentation of this. Get an inexpensive DVR, slap a hard drive in there, get some decent cameras and mikes and record this. If you want more resolution use IP-based cameras.Also, you should draw up a chronology. Illustrate it extensively with photos.Did either of you arrive recently? Your name implies you did. Do you know why the previous inhabitants left? Did they have similar problems?If I were you, I would try to ignore things like acorns. It makes your story seem less credible. Stick to the things that obviously pose a threat, in your opinion, and why.Keep in mind that it may be the kids, and try to ignore them. Kids will get bored if they are ignored. At the same time, set up a system that's recording motion when it occurs, all the time, including when you are away. Its easier and cheaper than you think.But if they are shooting anything at you, you want to know about it, and engage with authorities accordingly if its anything life or health threatening.

content: This is an electronics forum, I' not sure how you think we can help. Any particular reason you came here? It rather sounds like a matter for the local police.If you want to record sounds most microphones are designed for higher frequencies and don't pick up noise very well or may be designed to supress it. When my neighbours arrived a lot of noise started so I tried various ways of recording it and the only thing that worked was a sound amplifier thing i found left in the house when I moved in. It uses a small speaker as a microphone and has a headphone socket, the idea is that you can use it to hear things a long way off. As it was a cheap bit of junk it has no filtering and the larger microphone area being a speaker is perfect for those lower frequency bangs where a mobile phone did nothing.But if he is shooting something at you really it's a matter for the police.

How far is his property line from your yard? Is it possible he's installed some sort of ototoxin "sprayer" near the property line? Notice Maybe the click is a valve opening up? You would think you'd hear the sound of gas being projected out of some nozzle though.Does it only happen when you are in one area of the yard, or does it seems like it can be targeted?Wild...I feel terrible for you.

content: set up some cameras with infrared capabilities covering 360 degrees of your property, add some ir illuminators to extend the distance of the cameras view at night. record the activity, once you have what he is doing recorded, get the police involved once you have evidence. this might land him in legal trouble, but still, ask the court for an injunction/restraining order, as then you will have the proof to be able to do that. then when he violates that you can seek damages and likely he will go to jail if he doesn't already go to jail for what he is doing. Also, seek the advice of a lawyer before doing anything.

Ended up with lawyers at 50 paces over many years, over $100,000 spent on legal fees, won the case, then lost the case on appeal, and so then sued their original lawyer for a bad job. Over a decade of their life ruined.If I was living next to such a whackjob, I'd move, it will never end.That being said, the others that said this is an issue for the cops are right, gather evidence and contact them.

content: Quote from: HB9EVI on January 05, 2021, 06:46:28 pmCheck the law in your state/country. Foxes and coyotes are common pests in the US and I'm pretty sure it's legal to set kill traps in lots of the states. If the trap is legal and is on private land and it gets someone's dog, I don't see how they can take any legal action against you.If trapping is illegal, then how about poison? Dark chocolate/coco is very effective against coyotes and dogs.However, it would definitely be illegal if you shot your neighbour's dog, even on your land, unless it's attacking you. I'm sure there's a difference between the dog being killed by a trap/poison which is legitimately used to control pests and being shot.Quote from: Manul on January 05, 2021, 05:20:01 pmLook up microwave auditory effect.https://en.wikipedia.org/wiki/Microwave_auditory_effectQuoteIt's true that poisons can cause tinnitus, but I doubt it would be acute and it's a bit of a coincidence that it only happens, when he's outside. If it's a gas, he'd have to be using lots of it and it would affect other animals too. Going by the description, it seems to be too focused, to be a poison.

I'm guessing it was pretty cheap.You could ping someone with it across the room, and if the beam hit them they'd hear a clicking sound. I understand this isn't 'hearing' the beam, it's the on/off modulation of the beam causing a sympathetic vibration, and the subject hears that.Very low power and no ear ringing effects with it though.If you don't know what it is when you hear it, the effect is pretty unsettling.

The importance of Aspergillus fumigatus on the surface of wood dried in kilns is accentuated by its ability to produce tremorgenic mycotoxins. Eight strains of A. fumigatus from five different sawmills were isolated and cultivated on liquid media, and one of the strains was also cultivated on wood blocks. Extracts were prepared, and the tremorgenic reactions were induced by oral administration of extracts to rats. Extracts of the strain grown in liquid medium and on wood blocks induced very strong tremorgenic reactions when administered orally to rats. Four other strains induced mild tremorgenic reactions. High-performance liquid chromatography analysis revealed two tremorgenic mycotoxins, verruculogen and fumitremorgen C, in the five toxic strains. One nontoxic strain produced detectable levels of verruculogen. These results, coupled with the known resemblance of the acutely toxic phase of wood-trimmers' disease to the symptoms produced by these tremorgens, imply that wood-trimmers' disease and similar occupational diseases are, at least in part, mycotoxicoses.

content: if dog cant be treated as property, then assuming its a living soul like children under custody, if its tresspassing and made damage to other's property or life, the custodian should be charged in court or fined. if the law doesnt have such rule, the law is stupid, hence the more clever one (victim) should take action imho.

content: That neighbor clearly has a problem with anger management. He owns dogs that he's apparently unable to handle. I'd say, there's at least some probability he owns such a device already to discipline/punish his dogs.

content: Quote from: rstofer on January 05, 2021, 05:53:37 pmThis was my first thought as well. Does the popping/click sound anything like the click at the start of the recording innkeeper posted? You wouldn't necessarily hear the echoes of the discharge that follow it in the recordings.

content: Quote from: Manul on January 06, 2021, 01:04:20 amPeople love dogs, because people keep them as pets, so I knew the suggestion of kill trap/poison would be contraversial, but they're no different to any other pest animal and can be worse, in many respects: at least foxes, coyotes, wolves etc. are part of the natural ecosystem.I would have told my neighbour that something was attacking my chickens, presumably a wild animal and warned him, that I was going to put poison/traps on my land, because I know he has dogs. That way you give him the opportunity to deal with his dogs and show concern, by warning him first. The idea would be to not make it sound like a threat, but to inform him of the situation.I like dogs, cats, as well as foxes, but if kept hens and they were attacking them, I would take drastic action.

content: This story is spectacular, and I don't believe easttexasnewbie should be ruled out as a troll. Or perhaps this is some sort of homage to the fictional Sheldon Cooper, famously from east Texas and was terrorized by his neighbour's chicken.I mean he seems CCFCP to me.

content: LOLOne of my first thoughts was also "Hmm...this sounds like a movie,...am I getting trolled?"What's funny is thatmanygood ideas were proposed, including one that probably makes a lot of sense: A "pain field" or a high powered ultrasonic generator. But the OP comes back and says "Gosh I really thought you guys would be able to help, too bad." The OP has not responded individually to any of the proposed ideas, has not really provided any additional information, and overall does notseemall that interested in brainstorming with the people on this forum.That said...Not everyone is familiar with how an internet forum works, and many people are probably not familiar with the etiquette or features.Original poster (OP), if this is real, please look back a few posts...I think there is some good information. If it is some ultrasonic generator thing, here's what I would try:1. Get a laptop computer with Audacity2. Get a cheap USB microphone capable of 192KHz sample rate3. Discretely set the laptop up outside, in an area where you usually get zapped.4. After it's happened, check Audacity for a matching 20-30KHz signal, time correlated to when you got hit.

content: Quote from: TimNJ on January 06, 2021, 09:18:54 pmUm, sample rate does not equate analogue bandwidth, just like my mobile phone could not record crashes and bangs in the normal audible range but some piece of junk left behind by the last owners did.

content: Quote from: Simon on January 06, 2021, 09:30:17 pmYes..but hardly any manufacturer of PC based microphone is going to advertise the response above 20KHz, unless you buy a microphone specifically for ultrasound measurement. Those specialty microphones are much more expensive. At least I've not found anything cheap yet.I've checked a few Knowles modules on Digikey. Their rolloff is well above 20KHz, and many look useable well after 30KHz, providing the pre-amp has the bandwidth too. Obviously YMMV, depending on what microphone the manufacturer is using.So, maybe what I should have said is: Take a gamble on a cheap high sampling rate microphone, buy yourself a dog whistle, check if the microphone picks it up, and then do all the other stuff.How's that?

content: All things considered the story looks on the legit side, yet some things look strange. Like for example, when multiple people started suggesting surveillance, he said that he has 16(!) IR cameras on 2 acres teritory (which is not big) and sound recording, but somehow also implies that there is zero hard evidence collected including all the events of stone throwing and other things. How so? He explains, that neighbour may know the camera locations by checking with a phone. Ok, fair, but this neighbour is an interesting guy. Usually there is corrrelation between brain power and offensiveness. The neighbour is so smart to avoid notice, but wastes his time in all this offence. I don't know, maybe.Anyway, about sonic guns. Non ultrasonic ones will be heard like a siren by everyone around. Fact. Ultrasonic ones should be more stealth, but I hardly imagine them being so effective from 100 feet distance, or it would need several kilowatts of power. Maybe I'm wrong, but if I would have oportunity, I would happily volunteer to stand 100 feet away from any ultrasonic gun below 1kw. I bet it would not make big effect. Again, maybe I'm wrong. Does someone have first hand experience?Small electret microphones should pick ultrasound well. Even if it rolls off, who cares, we are talking about very high power signal here, it will pass. It can be checked before by scraching surfaces or blowing whistles (they should have high harmonic content).
