10 Best Silent Drones 2020 - Buyer’s Guide & Reviews

In recent years, drones have become widely used in various fields: from professional photography, extinguishing fires, surveillance to the delivery from online stores. However, the sound that drones make are reminiscent of the buzzing sound of an insect, which can make flying a drone annoying. As long as the drones have moving parts by which they fly, they will always make some kind of noise. The propellers and motors are those that make the buzzing sound during the flight.  Also, the study showed that the results of buzzing noise is annoying.

Manufacturers always have noise in mind when they are designing their drones, so they try to reduce it. However, there are some drones that are designed a little differently and have better motors and propellers, which makes them quieter. For that reason, more and more buyers are interested in silent drones. Here we present you the 10 best silent drones that you can buy.

(Below is a detailed list and reviews of all these drones)

  • Propellers

The noise that a drone produces mostly depends on the type of propeller that drone has. The main factors considered on the propeller are: size, shape, prop pitch and if the ends of the props are tipped. Smaller propellers usually spin faster, and thus creating a buzzing noise.

  • Motors

Drones have two types of motors: brushed and brushless motors. The mostly common used motors today on drones are the brushless motors, because they are quiet and have the better quality. Also these types of motors can generate much more torque which is also important.

  • Speed of Rotation

If the drone has small propellers and they spin faster, the buzzing noise will be higher. The goal is to have larger propellers that spin more slowly, making the drone quieter. The speed at which a blades cuts through air are the ones that produces noise and vibration.

Buying Guide: How to Choose Best Silent Drone

Before buying, you first need to know for what kind of purpose you will be using your drone. Will it be for fun or for professional use? There are some things to consider in order to choose a quality and quiet drone. In this guide we will help you to pay attention to only those essential things you need. Therefore, to get a silent and quality drone, these are the features you want your drone to have:

  • Propeller Design

We all know that propellers are the main cause of the drone noise. Models that have large propellers spin more slowly and therefore they produce less noise. There are various designs of drones such as quadcopters that have four sets of propellers, we have hexacopters with six sets of propellers and so on. Models like the DJI Mavic Pro Platinum are among the quietest drones on the market today. We also have „silent propellers“ which are specially designed to reduce the noise for a few decibels on your drone.

  • Type of Motors

Drones most commonly come with two types of motors: brushed motors and brushless motors. We only recommended brushless motors if you want to reduce the noise. Brushless motors are the ones that are most commonly used because they are generally quieter, more powerful and energy efficient. But if you have the combination of right propellers with motors, you can make the drone even quieter. Therefore, when choosing a drone, pay attention to the motor. Brushless motors do not require maintenance.

  • Propeller Shrouds

The drone produces the most noise by the propellers. The way that drone noise can be reduced by a couple of decibels is by adding propeller shrouds. The propeller shrouds reduce the noise in a way that the sound is diverted upwards, thus reducing the buzzing noise of the drone drastically. Note: Not all drones can  add propeller shrouds, but those who can have an advantage in terms of reducing that buzzing noise. This does not come with the drone, but must be purchased separately and installed.

  • Body Design

Body design is important factor that highly determine the noises of your drone. If you want your drone to be quiet, it must have a thick and sturdy body. This applies when the drone flies, its internal components such as: motors, battery, electric boards and other components, need to be less exposed to a spaces where noises will escape through. So this is also a thing you need to pay attention to when choosing your drone. If you are in a store, feel free to take the drone in your hand and slowly shake it. If you are ordering online, try to find a review video on youtube and see how much noise it produces.

Silent Drones -Questions and Answers

Why Use a Silent Drone?

Today drones are used in a large range of spectrum for a lot of things. But if you need a silent drone, in the field which matters to you, then you need to choose the quietest model available. The quieter the drone, the more convenient it is to use. Here are some reasons for using one.

Cases Where Silent Drones Are Used:

  • Surveillance: Police and army are the ones that are using drones for surveillance purposes, which is of the utmost importance for the drone to be as quiet as possible. Private research companies, large security firms, private investigators also use silent drones in their operations to monitor specific activities.
  • Drone Delivery: Drone industry is evolving and because of that higher standards are being set in this field also. One of these industries is delivery. When drones are carrying payload, workers who work with these drones need to have quieter drones so they do not affect their work. Therefore, the advantage of silent drones certainly plays a role in this large industry as well.
  • Professional Filming: Drones buzzing noise plays a big role here also. While shooting some scenes, it is important to keep it as quiet as possible. Noise-making drones can distract actors on the scene, and other objects such as birds or some animals. Also, if you want to capture the sound of nature or waterfall, it is advisable to have quiet drones as well.
  • Traveling: A lot of people love to capture their precious moments with some video material during the travel. Therefore, it is advisable to have drones that do not make too much noise. Drones that make buzzing noise in many situations can irritate a lot of people around you as well.

How Quiet Are Drones?

Drones make noise between 75 and 80 decibels during their flight. Those drones that can be considered quieter produce a sound of about 65 to 72 decibels at a distance of 3 to 5 feet (~1.5m). But there are just a few drones on the market that meet those criteria.

Can Drones be Silent?

Drones produce buzzing sound by propellers, so they can’t be completely silent. The models that we have described in this article are currently the quietest drones on the market. Sound is produced by the vibration that is generated by the motors and propellers that keep the drone in the air. The military is currently working on silent drones, which do not produce sound, but you will not find such things in stores.

Where You Can Use Silent Drones?

Silent drones also have applications in some industries where less noise is required. Police use drones for surveillance, which means that drones must be quiet and unnoticeable to perform such tasks. Also, when shooting amateur and professional films, the noise should be reduced to minimum so they do not interfere with the scene.

Conclusion

Silent drones are used today in many areas such as surveillance, rescue missions, filming, or for shooting movies. Therefore, silence plays an important role, and it is advisable that you choose a quiet drone for performing such a task. In this article, we explained what factors affect the sound that a drone produces and a ways how you can reduce the sound.

We have learn that silent propellers and brushless motors reduce the drone sound for a few decibels. Then we listed the top 10 silent drones that are available on the market and described their main advantages and disadvantages. We hope that we made it a little easier for you to choose the most optimal silent drone for you.
