Anyone else been getting interference on their EVP recordings near old cemeteries lately?

Been getting this exact thing round Holbeck cemetery in Leeds over the past few weeks. Static bursts that don't match anything on the baseline recordings, then what sounds like rhythmic clicking underneath it all. Nothing I can explain with the usual culprits - nearby traffic, overhead lines, that sort of thing.

What equipment are you lot using when this happens? I'm on a Zoom H5 and wondering whether its a hardware thing specific to certain recorders or whether people with completely different setups are seeing the same patterns.

The really strange bit for me is that it only seems to happen in one particular corner of the site, near the older Victorian section. Same spot every time. Has anyone else noticed the interference clustering around specific areas rather than being spread across the whole location? Makes me think its not random noise, there has to be something drawing it to that spot. Would love to compare notes with anyone whos done systematic baseline testing across different parts of a cemetery to see if they get the same kind of clustering.

@DurhamOtter the rhythmic clicking is interesting because that's actually one of the harder things to explain away. Random interference tends to be, well, random - but structured patterns like clicking suggest either a mechanical source nearby or something genuinely worth investigating further.

One thing I'd check first is your recorder's own motor hum interacting with the environment. Old stone and brick in cemeteries can sometimes create weird acoustic resonance that gets picked up as rhythmic artefacts. Run a control recording somewhere with similar stone construction and no "history" and compare the waveforms side by side.

That said, some of the most compelling EVP I've come across from cemetery sites does have that underlying rhythmic quality to it. Would love to hear the actual audio if you're able to upload it here. What recorder are you using and are you mono or stereo?
