A low hum in USA, Kansas City

Two alternate low frequency sounds. Duration of two alternate sounds is different each time. Could start and stop with any tone. In my previous apartment I was able to hear sound more often , my unit was on ground floor, now I live on first floor and I hear sound not that often. Looks like sound is generated inside my brain but is triggered on initiated outside.
