Yes, The DJI Mavic Air Is Louder Than The Mavic Pro And Mavic Pro Platinum Edition

The people of Ready Set Drone, made a test on YouTube, to check if the noise level of the new DJI Mavic Air was higher or lower compared to the original Mavic Pro and the Mavic Pro Platinum Edition.

Surprisingly the Mavic Air was the loudest of the three drones.

In another clip from Ready Set Drone, in which his son, Tate, seems to have made his YouTube debut, the noise levels between the three different DJI Mavic drones were compared. He tested the drones in a backyard environment and held the decibel meter about 6 inches below the front of the drone.

In the comments on YouTube, some people mentioned that the decibel meter should have been placed further away and maybe on a horizontal level at the same height as the propellers. The noise levels would drop significantly when you move away from the source. Maybe he will do that in a follow-up test?

Here are the results of their test:

  • 98 dB Mavic Pro
  • 93 dB Mavic Pro Platinum Edition
  • 99 dB Mavic Air

Why Noise Level Is Important?

One of the things you come to anticipate after flying a drone for a while is how the people around you will react.

Let’s be straight: if you fly your drone over a building to make on of those tilt down camera shots, I am sure that you will appreciate a quieter flight and avoid people complaining, police issues or any other embarrassing situation.

A phrase like “angry buzzing” sounds subjective, but it’s not just my opinion. A NASA study found that the sounds of drones were roughly twice as annoying to the average person as the same volume of noise produced by a car or truck. The noise of a drone is more annoying at the same volume because it’s a much higher frequency, one that happens to be particularly unpleasant to the ears of most humans.

DJI Mavic Pro Low Noise Propellers

 The DJI Mavic Pro Platinum, released back in August of this year, comes with a set of redesigned rotor blades that the company claims make the unit 60 percent quieter than the previous model. It tweaked the design of the blades by adding what’s known as a “raked wingtip.” The blades curve through the middle and angle back and up at the tip. To optimize for the new design, DJI also added electronic speed controllers that spin them at a different rate.

Once you get the drone in the air, the difference is even more striking. At a height of about 30 feet, you can still hear the whine of the original Mavic Pro loud and clear. At that same distance, the sound of the reengineered Mavic Pro Platinum almost completely fades away. If you’re actively listening for it, it’s still detectable, but the average bystander walking below wouldn’t pick up on the fact that something is close overhead. You can see a little visualization of the difference below. The gray spike around 8,000Hz is what really bothers most human ears with the old Mavic drone. The yellow line is a comparison of the sound produced by the new one.
