Recently I started getting a lot of emails regarding the quietest drones. How can we make them quieter? Are there any DIY techniques and much more? So, I thought of writing this article for those who love drones but hate the noise simultaneously.
A NASA study found that the sound of drones is more annoying than the rumble of buses and trucks. It was concluded that humans have become used to these vehicle noises. Though the noise of drones is far lesser in decibels than some vehicles’ sound, still, it’s more annoying.
In the Study, NASA researchers played the different samples of pre-recorded audios and asked them to rate the sound, which is annoying, and surprisingly, they rated drone sound more annoying than the sound of buses and trucks. You can read more about NASA Drone Sound Experiment over here.
Drones are some of the best inventions of our century. Their applications and future possibilities can transform human lives.
Making a completely soundproof drone is quite impossible, but we have a few drones that produce very little sound. Though not everybody complains about the sound, it could irritate many people.
If you are especially into filmmaking, then a noisy drone could be a problem.
The noise in the drone is coming because of the propellers, and sometimes build quality of the drone can also be a decisive factor in its noise level.
Several companies have started manufacturing quiet drones. Below are some of the benefits of owning a quiet drone.

Benefits of a Quiet Drone
Zero Disturbance
It can irritate your neighbors if you fly a drone daily. The sound of the drone can be an issue for the people and animals living in your surroundings.
It can also cause unrest among birds and animals living in trees. So, if you are going to fly the drone near a living being, you better buy one that produces the least noise.
Future is silent
Many companies are working hard to make deliveries possible through drones. And you make something noise as they are, it’s going to be a big problem.
To use them for pick and drop off objects, you have to make quieter drones.
However, it might look cool to see an autonomous flying bot coming for delivery, but its noise would be irritating at the same time. So in the future, we will see a lot of silent drones coming into the market.
Natural Sounds
If you want to capture nature’s sound, it isn’t easy because of these humming propellers. So, if the drone is silent, it can help you capture the sound of birds, trees, wind from a completely different angle. Especially in filmmaking, there is a much need for this type of drone.
How Do We Measure the Noise Level of a Drone?
The sound is captured in decibels. And every single increment in decibel number makes the sound three times noisier. In simple words, a decibel ratio defines the sound pressure on the human ear.
Asking which sound is irritating is a bit subjecting because the human perception of sound varies. What might be irritating for someone could be soothing for others? The threshold of the ear also varies from person to person.
Take music, for instance. A type of music you like, your friends might not like. Same works with the sound of the drone. It could not be very pleasant for some, while it can be like any other normal sound for others.
There are no specific regulations when it comes to drone noise. However, European Aviation Safety has certain guidelines. If a drone is flying 3 meters away, the noise level should be less than 80 decibels.
Below are some of the most popular drones and their noise level in decibels.
- DJI Phantom 4 Pro: 90Db
- DJI Mavic Pro: 84Db
- DJI Spark: 81Db
- DJI Mavic Air: 78Db
- DJI Mavic Pro Platinum: 77Db
- DJI Mavic 2: 76Db
- Parrot ANAFI: 72Db
How to Make a Quadcopter Quiet | DIY
People also have been asking about how to make a drone quiet. What can be done regarding motors and propellers?
If you want the least noise, you can go for a mini-drone. They are just for fun and produce far less noise than other popular drones.
Though, Some Users said by using the propeller guards helped them to reduce the sound.
While others said quad frames sometimes amplify the sound, you can remove the stickers and other extra stuff to decrease the little noise. I recently stumbled upon this funny thread on DJI Forum that you can also check.

What Distinguishes a Silent Drone From Others?
These are points that make a good drone silent:
- It requires a strong body that can accommodate all of the drone’s internal functions. Noises can be heard when the motor, battery, and other components are exposed. If not managed appropriately, this can be rather inconvenient.
- A good drone will also feature physical materials that dampen the vibrations in its body. This implies it can keep such vibrations from happening and becoming too difficult to tolerate. This is a significant advantage because vibrations may be rather harsh.
- A hefty body may also make a big impact on your drone. When the materials are thick, there is less room for the drone’s noises to escape and cause a disturbance. However, the materials should be robust and low in weight, otherwise, the rest of the drone may become clogged.
Conclusion
So, These are some of the quieter drones that you can find in the market. Though there is no drone made till now, which is completely quiet.
In the future, we might see a lot of advancements and that can reduce noise pollution. Till then, keep learning and enjoy your drone.
Happy Flying!!!
