I think a subwoofer would be needed, or a very very nice pair of earphones.

Somebody please correct me if I'm wrong: If the chassis ears were detecting said low frequency vibration, you wouldn't even know it was detecting it because earphones couldn't reproduce that sound. Voila, can't detect the hum?
Could be spot on!!
