Severe Tinnitus Following the Installation of New Electricity Meters

Since new gas and electricity meters were installed in my house on 9 February 2022, I have had a very serious problem with tinnitus. I also have had a feeling of strong pressure on my eardrums. Let me say straight away that this is nothing to do with smart meter communications; the hub responsible for mobile and Wi-Fi signals was removed one week after the meters were installed as a final attempt by the energy company to solve the problem. Various engineers I’ve been in contact with over this matter suspect the problem is most likely to be a switched-mode power supply or capacitors associated with it. I would like to know more about how such a device upset my health to the point that I do not feel it is safe to live in my own home. The energy company have refused to carry out any further work to investigate the issue and state that their meters meet all the current standards and are therefore safe.

I did not have any problems with the traditional analogue meters previously installed. I should add that I’ve been in houses that have smart electricity meters of various types and only in one of those houses do I feel my tinnitus tone is being amplified and none result in any pressure feelings on my eardrums. The first meter, a Landis+Gyr E470 was replaced with a Kaifa MA120 five days after complaining to my energy company. The Landis+Gyr meter was unbearable to live with any longer than that. The Kaifa model has seen me leave home twice for respite despite discovering on how to dampen down the tinnitus and greatly reduce the pressure feeling on my eardrums. The Kaifa makes an awful little noise which if I could hear that while in the living room, I could understand why my ears are being irritated. The Landis+Gyr also made a similar noise but a little quieter. However, should such devices make any audible noise at all? Some people don’t have the ability to hide these away in cupboards. I can hear the Kaifa meter 2 to 3 metres away with the cupboard door open where it is installed. A short recording of the continuous noise it makes can be heard in the following mp3 file:

My tinnitus grew into a significant problem within 24 hours of the Landis+Gyr meter being installed. I’ve had tinnitus in the past and was cautious to blame the new gas and electric meters at first, but I soon noticed this was very different to previous bouts of tinnitus: I found the affect would wane when away from the house and be amplified back to ‘horribly irritating’ upon return. The pressure feeling on my eardrums 'throbbed away' as soon as I got a short distance away from my house, it too would come back very quickly upon returning inside. When the Landis+Gyr meter was shutdown for replacement, it was an hour before the Kaifa meter was switched on. That is the only time I’ve been in the house since the new meters were installed on 9 February that my ears have felt calm, albeit the tinnitus tone only very slowly fades away. Unfortunately that short period of time was to end with a shock when the Kaifa was powered on; I felt a short burst of pain in both ears making me flinch in my seat. I was not watching what the fitter was doing and had to ask him what had just happened. He stated he had just powered up the meter with the distribution board still switched off. I’m horrified that simply turning on the meter could cause me pain, not to mention the fact the tinnitus and pressure feeling came back with this new meter.

With the aid of a friend who is also has a background in electrical and electronic engineering, I made the discovery that the effects of the meter can be reduced by turning off electrical devices plugged into the mains supply and found by turning off the ring main supplying the bedroom overnight, I could achieve better sleep, albeit still not adequate. Suspicion then was that the meter was emitting something being carried around the house via the mains cabling as opposed to just emitting something from itself. I requested help from the local power distribution company who sent out an engineer to check for electromagnetic fields. No unusually strong fields were found, however the engineer said he could perceive a high pitch tone and a bit of pressure on his eardrums. So far the only other person to sense something of what I am experiencing and I at least do not feel alone any more. He asked me to try powering down electrical equipment before turning the distribution board off and we both felt a relief from the pressure as soon as I turned off the television and surround sound system. The surround sound system along with most other audio equipment are now unplugged and the sense of pressure on my eardrums is much less noticeable. The engineer mentioned that tantalum capacitors and switched-mode power supplies can be a source of noise at frequencies in the audible range if they are defective or inadequately filtered.

Unfortunately the tinnitus tone has been gaining strength recently worsening my sleep down to just 2 hours a night. Hence I have had to leave my house again for respite, immediately achieving nearly 7 hours sleep on my first night away despite the tone having hardly subsided. I have used a tone generator to match the tinnitus at 14kHz. Sound analyser applications on my smart phone don’t show anything unusual at this frequency, but there is some low frequency noise below 100Hz and high frequency noise around 20kHz. Both are at low volumes, albeit I hardly think the microphone on a smart phone can be trusted at these low and high frequencies. However, what is interesting is that noise in the 17kHz to 21kHz range is hardly present when I am in other houses with smart meters where my tinnitus is not amplified and it is present in the only other house I know where my tinnitus is amplified. It could be a red herring, but there must be strange harmonics involved one way or another.

I’ve spent a great deal of time researching the Internet trying to find out about the problems with tinnitus and smart meters. I find people reporting life affecting tinnitus within two days of having smart meters fitted and then the forum responses where they posted concentrate on the arguments about Wi-Fi and mobile phone signals, neither of which apply here and then they soon degenerate into conspiracy theories about smart meters. (I’d have been very disturbed by tinnitus for the last 20 years if I had any sensitivity to radiation from mobile phones and Wi-Fi routers.) I’ve been in touch with the British Tinnitus Association and they have confirmed my case is “not without precedent”. I’ve had an email discussion with a specialist audiologist who states that the link between electrical apparatus and tinnitus is not scientifically proven but it is known some people can be hyper-sensitive. I’ve not knowingly been sensitive to any electrical devices in the past. I've had a hearing test which proves my hearing in the normal range is very good for my age, just some mild loss in the 7kHz to 8kHz range. The tone generators I used to match my tinnitus show I can hear tones up to around 15kHz, subject to the quality of these tone generator apps, websites and speakers within my smart phone and attached to my computer.

Maybe the arguments over smart meters and health problems have been clouded by the debate on Wi-Fi and mobile phone signals rather than the quality of the electronics in these meters. The electronics engineers who have pointed out the problem is likely to be the switched-mode power supply or capacitors within the electricity meter have done so independently, based in three different countries, which proves to me there is some concern about these components which obviously are in lots more devices than just meters. There is a difference though: I have two devices which have power supplies, almost certainly switched-mode, that make audible noises, but these can be turned off and would be replaced if I suspected they were causing any health concerns. The electricity meter is not something that can be turned off and replaced by the householder, it has to be changed by the energy company and any interference with it is illegal. I’m currently left in a position where I am reporting health effects coincident with the meters being fitted, locational to my house, affected by household electrical equipment and I'm so afflicted I am renting accommodation at some expense away from home, but being told by the company they are not going to do anything about it. They asked me switch company if I wanted the meter changing again and issued me with a deadlock letter so that I could take my case to the Energy Ombudsman as the only alternative. Either takes more weeks than I would like to contemplate, I've suffered more than enough already.

As switching energy companies at the current time is very difficult and very expensive without having to make the unusual request to remove a virtually new meter, I have started a complaint with the Ombudsman and I need to supply them with as much evidence as possible to prove the electricity meter is causing my health problem. There does not appear to be anyway of enabling the meter to be replaced as a matter of urgency given all my personal evidence as described above. If anyone can provide any advice or evidence that the quality of these meters can result in problems like I am experiencing I would be very grateful indeed. If anyone is researching in this area I would be very happy to help them with my experience, I do not fancy a future where such tinnitus inducing devices are common to every home.

  • OK, I have another question for ARB. How do you know that the tinnitus is at 14 kHz. With what have you compared it?

  • Using tone generators. Ref answer to previous questrion here: RE: Severe Tinnitus Following the Installation of New Electricity Meters

    An unpleasant experience but worth doing as it virtually matches the noise on the mains I found later after purchasing an oscilloscope, at just under 14kHz. Certainly a match within the range of accuracy of the devices used but I am in no way qualified to claim QED on this correlation. Note my sound meter app does not show any significant acoustic noise at 14kHz. It does show background noise between 18kHz and 21.5kHz, some between 1kHz and 3 kHz and aso small amounts between 10kHz and 12kHz.

    Warning: Anyone trying to listen to a tone in the region of 14kHz using a tone generator app, please be very careful to start with the volume turned right down. If you can hear 14kHz after turning up the volume (50% of the people I've tried getting to listen to it can't), you will get an idea of what I is in my head all the time I'm conscious. You'll also understand why sleeping is an issue.

  • In the thread above are some claims that tinnitus cannot be a result of the operation of electrical/electronic equipment (partly by definition!!), with a reference to "science".

    It is well to point out, I think, that there is in fact substantial medical scientific literature and debate concerning a phenomenon called electrical hypersensitivity (EHS). I just spent a couple of hours following some leads, as a response to AR Brearley asking us to look at a Norwegian document.

    The Paris Prof. Dominique Belpomme, along with his collaborator Philippe Irigaray, maintains a database of French cases, and claims to have found biomarkers for the condition (some biochemical, some brain electrical phenomena). For example, https://www.mdpi.com/1422-0067/21/6/1915/htm Some researchers claim to have found specific cellular pathways by means of which some kinds of electromagnetic field energy can cause DNA damage https://www.spandidos-publications.com/10.3892/ijo.2021.5272  There is a 2021 review article by Leszczynski on evidence for EHS https://www.degruyter.com/document/doi/10.1515/reveh-2021-0038/html 

    Amongst the symptoms of possible EHS listed by Belpomme et al is tinnitus. So if the Belpomme hypothesis is right, tinnitus can indeed by a result of the operation of electrical/electronic equipment. 

    Note this does not fit completely with AR Brearley's case. He is measuring acoustic phenomena in the vicinity of electrical/electronic devices, and these acoustic phenomena are related to his tinnitus sensitivity frequency.  

    As far as I can see, the Norwegian report (which was prepared for a court case) and associated documents are more concerned with EHS phenomena directly, not those mediated by acoustic phenomena. It was posted by a Norwegian former telecommunications researcher and university lecturer Einar Flydal, who is interested in EHS, from whose blog I got the pointers towards the work mentioned above.

    This is how medical science - actually, quite a lot of physical science - works nowadays. People assemble data and experience, write it down, write it up, debate it (sometimes acrimoniously - Belpomme was displeased by the Leszczynk review, and wrote a sharp letter - unfortunately not open-access), and some time in the future EHS may or may not be recognised by the WHO. It is a very different process from some person here declaiming he "knows" that tinnitus cannot be caused by electrical/electronic equipment and indicating "science" as some kind of oracle for that piece of "knowledge".

  • Thank you for the above and taking the time to look closely at the Norwegian research document and related documents.

    I'm of the opinion that EHS is a bigger factor than the acoustics, though it may be a combination. My initial thoughts in my early posts referred to the ultrasound measurements I was making in my house which when compared to other houses I found a correlation between what appears to be low level background ultrasound being present and tinnitus being induced. No background ultrasound, no apparent inducement. Plus there was the similarity of the tinnitus tone I hear to the tone I hear whenever I trigger my mother-in-law's ultrasonic fox deterrents. (These deterrents do not induce tinnitus, at least not in the short amount of time I suffer them - the tone probably would ring on for a while if I had to listen to them for a long period of time.) It remains possible that ultrasonics are part of the problem, as Mike (mapj1) points out, switched-mode power supplies can be noisy at these frequencies. Can these frequencies be carried over the household wiring and emitted? That seems harder for me to understand than EHS where the 'dirty electricity' is known to be spread around houses via the cabling and there's certainly a correlation between proximity to cables and equipment to how strongly I feel the tinnitus is being induced. The Faraday Cage I've built around the meter and service head is saving me from having to move out of my house until the problem is finally resolved as the RF problem is strongest close to the meter when unshielded.

    Once I bought and used my oscilloscope to find that there is a peak of electromagnetic noise on the mains wiring so similar to my tinnitus tone frequency, I now believe that EHS is the bigger factor. Acoustically I cannot find noise at the tinnitus tone itself, but maybe harmonics are responsible. Apart from tinnitus I do also have symptoms other than tinnitus that tally with symptoms listed on various sources of EHS symptoms such as the Norwegian research document and https://www.mcs-aware.org/electro-sensitivity/185-ehs-symptoms (See my table posted here in my day 124 update: RE: Severe Tinnitus Following the Installation of New Electricity Meters A brief update since the meter was changed to the old digital display meter: The tinnitus is worse than the Kaifa MA120 but less than the L+G E470. Less tingling sensations but some unusual twitches occasionally - only when in the house.)

    If I was to list all EHS symptoms I've found on the web it would be a very long list, but if low frequency radiation can interfere with people's nervous systems, then there's obviously lots of possibilities and the variation of symptoms and their onset are reasons why EHS is being difficult to establish as a problem. If my tinnitus tone turned on and off with the meter being powered on and off, would be no problem establishing the cause was the meter. (It probably would not be deemed "tinnitus" before anyone makes that comment.) Alas, tinnitus is not like that, it builds up and fades away slowly and speed differs between different people. Other symptoms have taken weeks to develop.

    One thing that I have yet no understanding of is how audio equipment in my house puts pressure on my eardrums when plugged in on standby. That reaction is very quick when turning on and off and been witnessed by another person while in the house. Indeed it was his help that identified the surround sound system as being the main cause of that eardrum pressure. Obviously that system has been kept unplugged except when testing the phenomenon and it is still bad with this old meter that has been installed. Solving why that pressure feeling happens may just help prove the rest of the problems.

  • be aware that when on standby a lot of devices drop back to a sort of 'woodpecker' or 'squegging' mode where operation and therefore power supply load is discontinuous. Basically it powers on just long enough to charge the dc side capacitors with enough to do the standby thing, perhaps checking for an IR remote control wake up command, and then sleeps. This was first done with things like radio doorbell receivers, being turned on for a few tens of msec every second but organisd to come on 100% when there a signal is detected in the listening slot. The discontinuous modes for TVs on standby involve re-waking a few hundred times a second, and  I have no idea for your hifi .
    But it is very possible that there is a supersonic switch mode supply clicking on and off in bursts at a sonic rate inside. This will certainly put conducted signals on the mains,  which will have just enough filtering to meet the product specs, and may well also radiate acoustically.

    (Those of us long in the tooth may recall the old vhf TV (switched off in 1984) which was a source of a most annoying screech from the 10kHz line scan transformer and coils, and the switch to UHF, line scan more like 15kHz and only audible to an unlucky few.)

  • Thanks for that interesting explanation of what these devices do in standby mode. Our twin wireless doorbells are a suspected source of the pressure and one of the two plug-in bell units has been unplugged. Shame it's not easy to convert to a wired bell at our house without drilling through the frames of the uPCV door frames. I never expected it would take so long to rectify the meter situation otherwise I might have found someone with a very long drill bit to go through the walls. Fortunately the pressure effect is minor compared to what the surround sound system. I'm guessing the size of the speakers has something to do with the size of the effect.

    Just to ensure that there is no confusion: No eardrum pressure was noticeable in the house prior to 9 Feb when the first digital meter was installed.

  • No eardrum pressure was noticeable in the house prior to 9 Feb when the first digital meter was installed.

    Has it ever been measured? That is to say that it is easy to measure the pressure in the middle ear and to compare it with ambient.

  • Just how easy is it to measure? I can plug the audio equipment back in and get the effect on my ears back within a minute or two if it is easy to measure. (It has to be done in the house as the effect throbs away very quickly after I leave the property.)

    I am just pointing out that my eardrums did not feel to be under painful pressure before the introduction of the new meters on 9 February and that this effect may be a way of detecting meters that can cause the other symptoms which can take hours, days even weeks to appear, affecting people at different rates. My witness to the eardrum pressure noticed the quick throbbing away of his eardrum pressure after turning off the audio equipment at exactly the same time as myself.

  • All you need is a tympanometer and I feel sure that your ear pressures will have been measured in the hospital. Is your house pressurized (+ve or -ve)? If not, how could there be a pressure difference there, but not elsewhere?

  • I think Chris, the pressure feeling is actually a false reaction as per the tinnitus being the false sensation of hearing a sound. I had an engineer visiting the house who felt the same pressure sensation until I switched off the tv surround sound system, so not just me and I can safely say I do not live in a pressurised house.
