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.
The height and depth of vocal sound is called pitch. It refers to how high or low a sound is perceived to be.
The low point of a sound wave, where the lowest air pressure occurs, is known as the trough. It is the point of the wave where air particles are farthest apart, leading to decreased air pressure. Sound waves consist of both high and low pressure points as they travel through a medium like air.
Because the rate of change in the pressure in the air differs: high pitch has a rapid vibration, low pitch a slow vibration. Humans can usually hear from a low of 20 Hz (cycles per second) to 20,000 Hz. I'm so old that I do not hear much above 12,000 Hz any more.

The Drone
Not being sarcastic but in physics terms it is called noise
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.
The tanpura is typically made of wood, with a resonating body that produces the drone sound. The strings are usually made of steel and are plucked to create the characteristic continuous drone in Indian classical music.
A bus hum or drone refers to a low, continuous sound often associated with electrical devices or systems, particularly in the context of audio or power systems. In audio, it can manifest as an unwanted background noise caused by electromagnetic interference or grounding issues. In power systems, a bus hum may arise from the vibration of electrical components under load. Both terms describe a persistent, monotone sound that can be disruptive in various environments.
