Low frequency noise in house

Mostly at night there a droning and humming sound entering the house. Sometimes it's a vibration as I can feel the bed vibrating. It's louder inside then outside so I can't figure out where exactly it's coming from. Is there any sound experts that can help detect where it is coming from or help with blocking it out. Live in the south of Johannesburg.

An annoying problem, and one that may take some detective work to solve. 

Possible offenders that come to mind are appliances or pipes in or connected to the house, or vehicle traffic like trucks. Keep a record of when it happens. These are some sound experts that may be able to refer you to the right person even if they can't help directly:

Are you the only one hearing this or do other people too? I don't mean 'maybe you're imagining things', but it's a recognised phenomenon that some people, often at certain times and places, hear a 'hum' that others can't - it's often not certain why. Sometimes there's a physiological cause like tinnitus. 
Please let me know if you make progress with this, and if not I can make further suggestions.
