Low frequency (maybe infrasound) between houses-expert advice needed 2

[Helpmeplz12341234]

Hi

Thank you for looking at my post, I appreciate any input and am looking for some expert advice on my situation.

Regardless of this is on purpose or not I hope we can focus on the details below. My primary concern is if something is attached or touching my house

My neighbour is in a wooden house and I am next door in a cast concrete house, there is about 1 meter between us and both of our first floors are partly underground.

There is an excruciating low frequency noise coming from their house to mine and I don’t know how. As their house is wood I cannot see how they can do it without disturbing their living too but it is happening. Times are irregular and I have had everything checked in the house already (water/elec/air con etc...)

One important thing to note is my neighbour is a professional acoustic/sound engineer so this is why I am asking for your input

It is hard to record this low sound so I guess it’s under the hearing spectrum so maybe it’s Info or really low frequency. When I press my ear to the window I can hear it outside, I can’t hear through the concrete wall. When it is on my bed feels vibration when I am in it.

My only guess is a directional speaker in his underground floor with low level frequency coming out but I don’t know. Also if my bed vibrates from it would that mean whatever is making this noise be touching my house somewhere and it’s going through the structure.

The sound is loud and my ears are ringing from it. I have had my hearing checked out also.

Any input or questions are appreciated, thank you for your time

Turn off the light at night and then go into the alley with the stethoscope.

By the way - what is the plan? You cannot prove anything and they won't stop. Apparently the cops won't help anyway.

Did you say you are moving?

Ya, moving. The law here doesn’t cover this type of noise only normal sounds like music, tried everything for help but to no avail. Actually this is the 2nd time this exact thing has happened to me so going to leave japan.

OK, so to recap, you've lived in two separate dwellings where your neighbor(s) are audio/sound experts generating sounds that cannot be recorded and that only you can confirm hearing?

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!

Bad wording by me, 2nd time someone did not want me living near them.

I have worked on noise annoyance projects. Typical tasks have included:
1) Detailed questionnaire to define problem
2) Sound surveys indoors and outdoors to identify suspected sound sources, sound paths, and correlation between measurements and problem description
3) Recording sound monitors placed inside dwelling and outdoors near suspect sources
4) Quantify sound/vibration problem based on observations and measurements
5) Conduct special sound/vibration tests as needed to define specifications for noise control methods and materials
6) Noise/vibration control recommendations based on the actual problem findings
7) Sound surveys after installation of noise/vibration control

"my neighbour is a professional acoustic/sound engineer" Your neighbor may or may not have the environmental and noise control skills to perform the tasks listed. Make a friend and see if he/she can help with your problem. There are many people with exceptional hearing for low frequency and low amplitude sound combined with contributing annoyance factors. It is technically possible that the sound (if present) in your neighbor's dwelling is lower than yours and that he/she does not have the same annoyance. Nothing stated so far is convincing that it is "100% your neighbour".

Gas meters, piping and appliances can product unusual sound/vibrations. A "service technician" may not recognize anything wrong. Here is a sample noise issue:

I think he did use a company that I mentioned earlier, it’s too professional imo

I was just hoping for some professional input here as I would love to get some solid evidence, I’m moving but it’s heartbreaking that it’s easier for people to call me paranoid then believe me. It’s so cheap and easy to get this kind of equip these days

Once again the a-hole wins

Unfortunately the only evidence has be presented by someone named "Helpmeplz12341234"

Experts can only help with qualified facts.

The OP was helped by professionals, but he didn't realize it!
