Drones can be loud because propellers travel quickly through the air and displace large amounts of air rapidly. This creates pressure spikes as the propeller spins, causing a distinctive buzzing noise. A lot of noise is also created by the propeller blades’ rapid motion and the effort of electrical motors.

Drones also make higher pitched buzzing sounds than helicopters, which have much lower frequencies because their larger rotors don’t need to spin as fast to generate the necessary power.
