The Quietest Quadcopters On The Market 2021

Quiet that Quadcopter!

Unless you’ve spent the last several years living under a large soundproof rock, you’ve probably seen (and heard), the remote controlled airborne drones known as quadcopters. These devices come in all shapes and sizes and they range in price, sophistication and carrying capacity. The smallest are no more than inexpensive toys while professional versions can sport powerful high definition cameras, precision guidance and flight controls. Before we get to the quietest quadcopters, let’s explain through the market a little bit.

Entry Level Quadcopters

Entry level quadcopters are fairly easy to learn to fly. With a few hours of practice even a novice can become proficient. The more sophisticated ones come with tons of features, for example the Return to Base mode causes the unit return to a specific location whenever it loses contact with its controller or is low on battery power. Professional models are also equipped with highly accurate sensors and GPS. Many can be controlled from your smart phone as well as stream live video directly to the screen.

 

Modern Quadcopters

Modern quadcopters can lift fairly heavy loads, and as anyone with half an eye on the news can attest, they are being employed by many businesses to deliver packages, drinks, medical supplies and even pizza on a daily basis. Pro models been used to shoot amazing panorama and action scenes in many of your favorite movies and online videos.

An emerging trend in this hobby-sport is use of quadcopters for nature observations. Drones would seem to be ideal devices to spot birds in flight or during migration, not to mention animals that dwell in the forest canopy or really any type of remote nature photography. The challenge that quadcopters face in these environments is noise.

Quadcopter videos that can be found online are almost always silent or have an appropriate music bed. The resulting videos are often breathtakingly beautiful. But if you were actually present when these videos were being shot you would likely have wanted to shoot the producers instead. The reason is that the copters themselves create noise, and it can be incredibly loud and annoying in some cases.

 

Large Camera Copters

Large multi-rotor camera copters (some having as many as eight individual rotors) sound like the angriest swarm of giant robot killer bees that you’ve ever heard. Most folks instinctively shy away from anything that sounds like a giant swarm of angry insects. Animals and birds are just as reactive to bee swarms as we are. Noisy quadcopters cause the animals that are being observed to act in unnatural ways.

Part of this is of course just due to the physics of flight. You have a rapidly spinning propeller that is producing highly turbulent and in some cases actual cavitation. This turbulence and cavitation cause chaotic disruption of the air nearest to the prop and our ears detect these disruptions as high pitched buzzing.

In the case of a quad or multi-rotor air vehicle the problem gets worse. Not only does each of the props create additional noise but the combination of the sounds can actually add up. Multiple props cause both resonance and a set of harmonic frequencies that can be detected by our ears. This resonance and high pitched sound can be frightening to animals. Clearly you want the quietest model you can get, so here are the top seven picks gleaned from hobbyist and professional user’s experiences.

 

The Top 7 Quietest Quadcopters

The quadcopters listed below have been rated as being the quietest. Noise is subjective and they may or may not be appropriate for your specific application.

Last word:

Almost all the hobby and professional sites recommend that drone users experiment with different types of aftermarket props to find the quietest combination that will still provide adequate performance and lift capability. Almost all of the noise created by any drone is due to prop balance, vibration and cavitation. Minimizing these sources of noise by properly balancing your props, ensuring the props are extremely smooth and clean and that they are made out of high-quality materials, (such as carbon fiber) will provide the best experience and lowest noise profile. Happy flying!
