I still have my own seismic sensor on my foundations since pre-earthquake times!

(Red trace uses an algorithm from the other 3 (x= l-r, y= n-s, z= up/down) to decide what is happening, above 3 is bad!)

There are a lot of options to check your marbles haven't escaped from above your shoulders.

I have been fascinated for a while by the worldwide reports of The Hum:

I see there is a pin fairly close to where you are located.

ashtonaut: I would suggest getting the vibration measured/monitored. There are absolutely companies that can do this for you. You mention that companies have said they don’t monitor that frequency, but you don’t mention what frequency vibration you are experiencing?

In my experience you can have vibration monitors installed (often glued) to a hard/stable surface (like a concrete driveway or fence), and left in place for a few days. They log the frequency and amplitude of vibration in all three axis, which can be used to produce a vibration spectrum which will be helpful. They should also clearly show when this is happening, and how often.

If you can get yourself some quantitative data you’ll be in a much better position to engage with CCC or other entities to troubleshoot further.

CCC services maps were mentioned above. You should confirm exactly which services run near your house and how far from your house they run.

I emailed several companies and this was the common response,

"Unfortunately, we don't provide residential services so wont be able to help you in this instance".

Here's another response,

"We only measure construction/demolition vibraitions in the range of 0.3 – 100 mm/s.

Our equipment would not have the resolution or sensitivity to determine very low level vibrations ~0.3 mm/s you require."

Another company said they can do an assessment, heir response,

"The issue you are describing can be very difficult to solve and to identify the source. We offer a vibration measurement service but I feel it would probably end up costing you a lot of money (Approx $3,000) and we may not be able to give you any useful answers."

If you know of a company that can help at a reasonable price or where I could get the equipment from, could you please PM me any information.

Also I have had a look many times at the services map for wastewater and fresh water, but don't really know what to look for, they have replaced all pipes and the original pipes from 1957/58 are still iunder road and foot path.

Thanks Peter

If you zoom right in on that map and look at the individual items in the vicinity of your property, you can click on them and they will tell you axactly what they are. Is there a particular access point or chamber near your property.

If you think of a standing wave in a pipe organ, and the vibration from that, you could get a similar thing happening in unground pipework. The result is where the amplitude is a maximum (your place) can be quite a different place from where it originates (say a pump station).

Perhaps @msukiwi can offer some more details on those sensors in use - might be good option for measurement.

Is it possible that vibration is being transmitted along the pipes that connect to OP's house?

In my job, I have an interest in minimising vibration caused by pumps in hydraulic power systems, on vessels. We do this in three ways: -

1) Cushioned mounts - the rubber cushioning absorbs vibration (whole system).

2) A gas bladder in a housing that clamps onto the pipe and suppresses noise and vibration (supply side).

3) Flexible joiners (low pressure side). They break continuity of the rigidity of the piping systems.

As will be evident, I'm not the engineer in this scenario. But maybe some food for thought there.

Here's the pipes infront of property,

One thing I'm not sure of, is it resonating from the Pump station machine underground to my place or is it from the pipes resonating/pressure and from the water mains or the vacuum system for the waste water??

Thanks Peter

I have a large Pump Station 600m from my house, have gone down there dozens of times when it is very bad here and I can feel the ground shimmering away in front of it with the same vibration but far more subtle than my place.

I have complained to the CCC about this and they have investigated and said it's not there equipment and there vibration monitoring equipment picks up nothing, case closed.

If it's distressing enough to spend a bit of money on them get a Raspberry Shake and present the council with a detailed log of what's going on, they won't be able to shrug off an actual seismic record.

How computer "literate" are you?

Can you locate QCNLive and install it with drivers for a JoyWarrior 24F14 USB Sensor?

Under QCNLive / File / Local Settings / Select "JoyWarrior 24F14 USB" sensor under the specific sensor to be used.

Save & Exit and restart QCNLive. Remove and replug the USB cable.

Should say found the sensor at the bottom.

Click the waveform at the top (2nd from left), click Sig.

Select period displayed on screen by clicking the left-right arrows with +/- on them. (10sec / 1min / 10min / 1hour)

Don't bother following ANY instructions for BOINC!

Sensor comes with a 2m USB Fixed Cable.

I can loan a sensor, tested working here.

Hi, thanks, yes I can do that, I will PM you later as at work at mo.

Thanks, I will look into Raspberry Shake PI instrument.

The Raspberry Shake was born out of the QCNLive project, they commercialised it so it was no longer primarily hobby / mass coverage based. Carl who wrote the original s/w gave up as a result!

Do your neighbours experience the same thing?

No, they don't feel it that I know of,. And yes it's in the white blotted out area.
If anyone can think of what it might be causing the vibration, please let me know

Thanks

Have you specifically asked them or had them inside your property?

Asking as a manufacturer in an industrial area was radiating an exhaust noise a while back and it took a few attempts to get it recognised.

Any one on your local whinge vines reporting it?

hsvhel,

My neighbour on driveway side feel it slightly once in a blue moon, neighbours on other side don't feel at all, When it's bad late at night and you can feel it outside, if I walk from driveway along foot path it dissipates and is gone just before there boundary.

No one has come to see me and I have asked many times, I have asked who to contact late at night when it is bad and they say they don't do vibration, only noise control.

Two senior CCC staff went and visited my neighbours about it to see if anyone else had vibration, my neighbour told me they said "the man over there think's his house is vibrating".

So, you can see the problem I'm having, even if I had proof of vibration, they will still say, it's not our equipment

I think all I can do is get a log or proof of vibration and try to match it to a source, then the media.

I still live in hope it will just go away like it arrived, but in 11 months it's gone from 4-6 hours to 12-15 hour's per day.

Jase2985:

im sure if there was vibration coming from somewhere in the neighbourhood someone else would have noticed and said something

Anything on your local community page on Facebook? would be the first place i would go looking for people experiencing similar things

Hi,

I just put up some info on local Facebook page yesterday and one person said pump station and pipes, some said heavy vehicles going past, but most where just mocking what I said.

The neighbours don't feel it, but researching online it does happen but very uncommon and can affect just one small area, from USA web sites regarding vibration and pump stations.

Keep on reporting it, our issue was coming from over 4KM's away. Some heard it, some not.

Once tracked down it was sorted very quickly. But it took ages to pin point.

Be the squeaky wheel
