I'f you're interested in silent drones, there's more than the decibels that you should be looking for, but that's a pretty good start.
If you're looking not to get yourself annoyed or be a bother to other people when flying, the pitch of the noise is something you should also take into consideration.
In this article we'll have a look at some of the most popular drones from DJI and how noisy they are, along with a suggestion for a cheaper GPS camera drone that had the most pleasant sound I ever heard in a drone.
There are many things that matter, but the most importat are:
Motors can be either brushed or brushless, on this list there will only be brushless motors, as they tend to be more silent and higher quality.
Speed of rotation
If the propellers are bigger and they spin slower, the sound is going to be more pleasant and less bee-like.
The drones on this list won't be only DJI, but this table and video from WeTalkUAV might help you figure out exactly how to diferentiate between drone sound levels.
Bellow there's gonna be my top 2 recommendations if you don't have the time to research further.
One of them is the most silent cheap gps drone I've ever tested, good for beginners and hobbyists.
And the other is a more expensive professional drone that's more silent than anything else you can find currently on the market.
Don't forget that for drones over 250grams you need to register your drone.
Dji Mavic Pro Platinum
70 Decibels (at 1m distance)
68 Decibels (at 1m distance)
4.1 mi (7 km)
4k - 3 axis stabilization
The original DJI Mavic is one of my favorite drones that I still recommend to this day, as one of the better camera drones you can buy.
Thing is, you can't entirely reproduce how silent the mavic Platinum flies by just adding some silent propellers to the Mavic Pro.
DJI has made slight tweaks in the design, motor and ESC specs so the battery is used more effectively and the drone flies smoother and with less noise.
1080p -no stab
Of course, this drone is more in the hobby/beginner category, but for a budget under $200, this is one of the best choices you can make.
It does come with solid GPS and a really REALLY good build.
The plastic it's made from feels fantastic and the 1080p camera actually can deliver some usable footage.
It isn't stabilized, but as you can see in my video review bellow, you can definitely stabilize in post processing and end up with a nice final shot.
5 miles - 8km
4k - 3 axis stab
However, this drone also makes for one of the most quiet drones I have ever flown, and that's exactly the reason why this is my main use drone.
The propellers come with a silent design from the package and the noise of the motors is lower pitched and considerably more pleasant than even smaller drones like the Mavic Air.
Being just slightly louder than the Mavic Platinum, this deserves a really good spot on this list, as it comes with a lot of features that you might be interested in like:
Gopro or 1080p included
This drone can also come in the package with an included action camera made specially for it. With that you can see the live feed directly on your phone through the included app.
It has brushless motors, which is amazing for this price range and somehow it's really silent and I love it for that fact.
It is indeed considerably bulkier than the others on this list, but it's more than capable to carry your camera and the build quality is outstanding.
Phantom 4/ Pro - 80 dB
The phantom series has always been very noisy so when the Mavic was released, people were amazed by how non invasive it was compared to the old quadcopter model.
Inspire 1 and 2 -83 db
This drone is on a whole different professional level, but even so, you must take into account that it's a huge and very noisy drone.
Mavic Air - 76 db
Even if it's smaller compared to the standard Mavic, this drone makes quite an annoying high pitched sound.
