Strange noises at certain spots

[stony]

While walking through the landscape, strange noises can be heard from time to time. For example, squeaking of chests or humming of the translocator.

Once I dug down at the spot and after 60 blocks I came across a tin vein.

Is that what these sounds mean or was that a coincidence?

Coincidence most likely.  If you're on a server, could be other players in the area perhaps.  And it may be possible that active translocators can be triggered by mobs.  But ones that haven't been found (and repaired) shouldn't be able to be.
