In music a drone is typically a low note that doesn't change, like you might find in bagpipe music or chanting monks.
I think the answer you seek is frequency. A low pitch equals a low frequency of the sound wave.
large,thick things produce a low pitch sound
A triangle has high pitch.
Trough
In an action in whitch the air is basicly "pumped" creating vibrations in the air known as "sound waves" through slower vibrations, low-pitched sound is created, keeping in mind that slower doesnt nessisarily mean quieter. The volume has to to with the depth of the sound waves (distance between the highst and lowest points), and the speed affects pitch. So a tall tight sound wave is going to be high pitch and loud, and a short tight sound wave will be the same pitch, just quiter. That all being said a low pitched sound wave will be more spread out rather than tight like sardeines. Two examples of mediums that create a low pitch sound waves are a sub-woofer and a bass drum, that essentially vibrates the air.

The Drone
Not being sarcastic but in physics terms it is called noise
Bees, wasps and teachers.
The loud drone sound is from the wheel bearings. I had to replace the two front wheel bearings on my 2004 Mazda3 2.3. try rotating the tires first, because a bad tire will sound almost the same. I also have the same problem. I did rotated my tires but find out all suspensions need to be replace. Bad suspensions cause tires to cupped and make those drone noise.
Jets roar, small planes drone, both types whizz or zoom.
