87 Accord, yep, my car is falling apart.
 Will wheel bearings make a  medium pitched humming sound when they are starting to go out?  Generally increase in road speed  =  increase in sound pitch.  Also amplitude changes when the vehicle is accelerating while turning at higher speeds e.g. converging freeway merging ramp.  You know, those ramps where you make a 270 degree turn in order to get on the freeway going in the opposite direction.
 Also generally this sound is mainly noticeable between 40-70 mph.  I jacked up the car today and spun the wheel freely with the car in neutral and even then I could hear this sound, it was just more subtle.
 So I just want to make sure i’m on the right track here.  I understand wheel bearings are relatively inexpensive to replace.  And just for the record car has original bearings still.
Wheel bearings tend to make a hum / grind / roar that increases with speed, and judging by your description, I’d say yours are about toast.
