My car had the same symptoms, got loud at 40, quieted at faster speeds, then got loud again at 60. It turned out to be a problem with the wheel bearings. They replaced the assembly in one of the wheels, $220, and the car sounds normal again.

Overdrive is an extra gear assembly in the transmission that allows the engine to run at a lower speed (lower RPM) when you are travelling at higher speeds on the highway or freeway. For example, if I am driving my 1995 Explorer at 62 mph in drive, the engine runs at 2800 RPM. If I am driving at 62 MPH in overdrive, the engine runs around 2100 RPM.
