Over the last year we've been having an issue with very low level train/underground noise coming into the studio.
In 30 years at this location we've never had even a hint of this before.
It sounds like noisy points or a gap in the track has opened up. After we made some enquires to the Transport for London noise department it went away, but now after Christmas its back..
I need to make some recording as evidence. What would be the best way?
The noise floor of the kit tend to swamp the actually sound and i'm not sure the mic i tried has the low frequency response.. I tried a DPA lav stuck to a wall but didn't really capture it.
Contact mics on pillars maybe?
Any one have experience in this?
thanks
