Have you ever experienced that buzzing sound over your head while walking through a street, park, or on the roof of your office building? That’s drone, buddy. Most people wonder do drones make a noise. Yes, drones make noise. However, the noise level depends on the drone. Let’s answer some of the most common questions about drone sound.
Do drones make a noise?
Yes, drones make noise. The rapid spinning of the propellers causes the sound. The noise level can vary depending on the drone’s model, size, propeller design, and flight conditions.
Some drones are relatively quiet, while others can produce significant noise, particularly when flying at high speeds or near the ground.
For instance, a DJI Mavic Air 2S produces around 65 decibels of noise at a distance of 30 feet. It is comparable to the noise level of a conversation or a quiet dishwasher.
On the other hand, a DJI Inspire 1 Pro can produce up to 80 decibels of noise at a distance of 30 feet, comparable to the noise level of a vacuum cleaner or a busy road.
Why Drones Make Noise?
Drones make noise because of their spinning propellers. The propellers create air pressure waves as they rotate, which travel through the air as sound. The faster the propellers spin, the higher the pitch of the sound and the louder it is.
If you are swinging a fan around in the air, the fan blades disturb the air, producing sound waves. The faster you swing the fan, the louder the sound will be.
Drones work similarly, but they use spinning propellers instead of swinging fan blades. The propellers create air pressure waves as they rotate, which travel through the air as sound.
How Loud Are Drones?
The loudness of drones depends on the model, size, propeller design, and flight conditions.
Here are details about the sound levels of different types of drones.
Consumer drones, such as the DJI Mavic Air 2S and the Parrot Anafi USA, produce noise levels of around 60-75 decibels at 30 feet.
Professional drones, such as the DJI Inspire 2 and the Freefly Alta 8, can produce noise levels of up to 80-85 decibels at 30 feet.
Racing drones are designed for speed and agility and can produce noise levels of up to 90 decibels or more at a distance of 30 feet.
What Does a Drone Sound Like?
Drones make a buzzing sound caused by the propellers’ rapid spinning. The pitch of the buzzing sound can vary depending on the speed of the propellers.
The drone may sound like a bee, mosquito, or helicopter. Also, the drone sounds like a high-pitched whine or a whirring sound.
Do drones sound like helicopters?
Drones can sound like helicopters. Smaller drones, such as consumer drones, make a quieter buzzing sound, while larger drones, such as professional drones, can make a louder, more similar sound to a helicopter. The drone’s speed can also affect the sound, with faster drones making a higher-pitched sound.
Drones are quieter than helicopters, but the sound can be similar, especially for larger drones flying at high speeds.
How far away can you hear a drone?
You can expect to hear a Consumer drone up to 100-200 feet, professional drones up to 200-300 feet away, and racing drones up to 500 feet away.
- How to Make Your Drone Quieter?
There are many things you can do to make your drone quieter.
- Use quieter propellers. Several different propeller designs are available, and some are quieter than others. Look for propellers that are designed to reduce noise.
- Choose a drone with enclosed propellers. Enclosed propellers tend to be quieter than exposed propellers.
- Fly at a higher altitude. The further away the drone is from you, the quieter it will sound.
- Avoid flying over densely populated areas. It helps to reduce the noise nuisance to others.
- Use a noise reduction shroud. A noise reduction shroud is a device that fits around the drone’s propellers and helps to absorb sound waves.
