A silent drone will allow you to get close to your target (human or animal) as possible without being detected.
In doing so, you can maximize the amount of intelligence collected. (Source)
The quietest drone has noise ratings in the range of 70decibels- 81 decibels.
The payload processor is the most expensive element of modern-day drone technology.
This element results in the dilemma that, while a drone should fly close to its target as possible, it should also be far enough to be unobtrusive.
To capture as many details as possible, drone manufacturers have come up with technologies that not only make the quadcopters quiet but also efficient in what they are designed to do.

Silent Drone Buyer Guide: Key Factors to Consider
There are several factors to consider when consider before buying a silent drone. These factors will ensure that you get one that meets your specific needs.
Propellers are available in different shapes and sizes and are subject to different types of acoustic testing and prototyping testing.
Batwing design are less noisy, and their design seems cool.
Large and Slow Spinning Propellers
Large and slow spinning propellers produce less noise. When the drone propellers spin slow, they generate less noise and can be easily camouflaged by background noise.
One of the drones that utilize this technology is the Vanguard from Airborne, which can operate quietly above 150m or 500ft.
This is the only drone on the market designed for stealth and long-range video surveillance with a 94 mins flight tile and a transmission range of 22 miles.
It costs around $46,000
Type of propeller motors
The type of motor determines how noisy or quiet a drone is. Ones powered by brushless motors are usually quieter, and they are more powerful and efficient.
Additionally, they last longer and need no maintenance at all.
Some drones have noise reduction shrouds which are effective in making it quieter. Sound deadening materials are used to reduce the noise produced by projecting it skyward.
Noise reduction shrouds were invented by Dotterel Technologies, a startup company owned by three brothers.
However, the trials the shrouds only reduce noise by 6 decibels. The noise will be reduced by up to 10 decibels after some improvements.
Final Thoughts on Silent Drone
Silent drones are multipurpose. They can be used for surveillance purposes without giving your location.
Lastly, a silent drone is also good for recording videos. The problem is most drones for recording videos are loud and often result in the recording of background noise
Above all, with a quiet drone, you’ll be able to avoid all these hassles easily.
