Low hum, like an electrical transformer, very strong but low frequency. Sometimes notice a pulse with it that I can feel the pressure on my ear drums. I generally do not feel well living in this apartment. When I leave I begin to feel "normal" again - more energized, more clear thinking. When I return to apartment I feel the "malaise" again within 15 minutes.
