Thanks for the input and ideas, all...

Here is a sample to give you a general idea of the noises in question;
194KB...3 separate ones @ 16 seconds total.

Without knowing the conditions of recording, or any reference to indicate
how loud it was, it is a bit difficult to tell what it sounded like in
reality. However at a guess I would say the cause is simply a very
lightweight floor construction. Is your apartment purpose built or a
conversion?
