Recently I started getting a lot of emails regarding the quietest drones, how can make we make them quieter?, are there any DIY techniques and much more? And much more. So, I thought of writing this article for those who love the drones but hate the noise at the same time.
Recently, A NASA study founds that sound of drones is more annoying than the rumble of buses and trucks. It was concluded that humans have become used to of these vehicle noises. Though noise of drone is far lesser in decibels in comparison to some vehicle’s sound, still it’s more annoying.
In the Study, NASA researchers played the different samples of pre-recorded audios and ask them to rate the sound which is annoying and surprisingly, they rated drone sound more annoying than the sound of bus and trucks. You can read more about NASA Drone Sound Experiment over here.
Drones are really in some of the best inventions of our century. Their applications and future possibilities can transform the human lives. Making a completely soundproof drone is quite impossible, but we have a couple of drones which produce very less sound. Though not everybody complains about the sound, but it could be irritating to many people.
If you are especially into filmmaking, then noisy drone could be a problem for you.
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 a quiet drone.
Zero Disturbance: It can be irritating for your neighbors if you fly 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 nearby living being then better buy one which produces the least amount of noise.
Future is silent: A lot of companies are working hard to make deliveries possible through the 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 future, we will see a lot of silent drones coming in the market.
Natural Sounds: If you want to capture the sound of nature, then it because quite difficult because of these humming propellers. So, if the drone is silent, then it can help you the capture the sound of birds, trees, wind from a completely different angle. Especially in filmmaking, there is a much need of this type of drone.
How do we measure the noise level of a drone?
The sound is basically 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 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. For some, it could be irritating while for others it can be like any other normal sound.
There are no specific regulations when it comes to drone’s noise. However, European Aviation Safety has certain guidelines, according to them if a drone is flying 3 meters away, the noise level should not be more 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 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 frame sometimes amplify the sound, you can remove the stickers and other extra stuff to bring down the little noise bit. I recently stumbled upon this funny thread on DJI Forum that you can also check.
