Have you ever wondered what a drone sounds like? This question came up with me as well. I was spending some time online with friends when this mysterious subject of drones arose. We talked about several things, but eventually the conversation circled back to an original topic: “Do drones sound like helicopters?”

Drones sound like helicopters, but they are not the same. The difference between a drone and a helicopter is that a drone can fly without a pilot on board, whereas a helicopter always needs someone to be in it. Drones also fly at lower altitudes than helicopters.

Drones certainly don’t sound like helicopters. That’s what my brother said when I showed him one of the more popular models on the market.

When companies started selling drones, almost everyone said they sounded like helicopters. This proved to be an issue for drone enthusiasts and drone sellers who wanted to make them appealing to a wider audience.

Drones sound like loud humming, a helicopter is really loud but they are different. I think people who love to fly them are a bit like the kid that bangs on pots and pans when they hear music.

It is just the thing they’ve always loved to do even if no one else pays attention to it. You see, drone enthusiasts are so passionate about their hobby that they want people to know and see what they do.

Drone Sound Levels

Drone Sound Levels

You may have noticed on a summer afternoon the sound of a bumble bee hovering around your backyard, or that feeling you get when you think your cell phone is buzzing in your pocket—but it isn’t.

These are a few examples of the sounds drones make while they’re flying. For most people, a drone’s noise level is barely noticeable and can be compared to the humming of a sewing machine. They fly much more quietly than helicopters, which are known for their loud whirring blades.

Helicopter Sound Levels

Helicopter Sound Levels

You probably know that helicopters can be pretty loud. After all, you’ve seen them flying over your head before! But what is it about them that makes them so noisy? And how do their sounds compare to those made by drones?

Helicopters are so noisy because of the mechanics involved in keeping the craft aloft. Helicopter engines are the primary source of noise — a single helicopter engine emits about as much noise as a sports car revving at full throttle. Engines make even more noise when they are being pushed to produce more power for takeoffs or other movements.

Because helicopters have multiple rotors and an open cockpit, it’s not uncommon for its sound to reach 90 decibels when passing by at just 500 feet away from where you’re standing below. That’s louder than a motorcycle or truck driving past you!

Which Thing Causes The Sound In A Drones

There are few things that can cause sound in drone, all of those are given and explain below in detail:

The Propeller System

Underneath the body of most drones, you’ll find a spinning propeller system that is the key to drone flight.

The design of these spinning propellers is very similar to those of helicopters. However, the main difference between helicopter and drone propellers is that drones are more efficient in their design and use less energy. In fact, some drones are so small that they don’t even have a separate motor or require any batteries at all.

Dual Propellers With Tilt Rotation

Drones with tilt-rotation propellers, then, are the most maneuverable and fastest of the bunch, because they can zip in any direction at a moment’s notice.

They tend to be harder to fly (some would say more fun), but you’ll definitely need some practice first. If you’ve ever tried to make a remote control helicopter hover or stay in one place without crashing into something, you might appreciate this.

Speed And Maneuverability

Let’s start off with the most obvious reason drones sound different than helicopters. For starters, drones are usually faster than helicopters. Most drones travel at a speed of 35 miles per hour or less, but some military drones travel in excess of 150 mph. Most civilian helicopters top out at 140 mph.


Helicopters are notoriously inefficient from an energy standpoint, which is why they’re so loud. Helicopters require a considerable amount of power to keep them airborne for long periods of time. Drones on the other hand are extremely efficient when it comes to energy use.

They can stay aloft for hours without having to return to base for a recharge. Not only does this make them more cost-effective, but it also makes them a lot quieter since they don’t have to continually guzzle down energy from their rotors like helicopters do.

How Do You Know If A Drone Is Near You

How Do You Know If A Drone Is Near You

The truth is that drones come in a variety of sizes, shapes, and colors. Some are large, like a small car, while others are small enough to fit inside the palm of your hand. Most drones have blades on top that propel them through the air, but there are also jet-type drones that can reach supersonic speeds.

In general, if you see something flying or hovering above your neighbor’s house or in an area where you wouldn’t expect to see airplanes or helicopters, it’s a good idea to consider whether it might be a drone.

Drones make noise and some do sound like helicopters or humming noises (depending on their size). The best way to prevent hurt feelings or unnecessary anxiety over what someone is doing with their drone is by being proactive.

If you have questions about where they will fly their drone (or why they need a drone) then ask! By understanding some of the common uses for drones from inspecting cell phone towers and finding missing children to scientific research and search & rescue operations you will be able to rule out nefarious intentions behind the presence of an “unidentified flying object”

Difference Between Drone And Helicopter Sound

If you are as ignorant as we were, you probably assume that drones sound like helicopters. While both aircraft produce noise, the sounds of a drone and a helicopter are actually quite different. Helicopters produce a whirring noise, while drones make a buzzing or humming sound that is not as loud.

If you have ever heard the hum of an electric motor in the distance and thought it sounded like a swarm of insects instead of an aircraft, then you have already heard the noise produced by drones!

It might seem pretty strange to associate this type of sound with one particular type of technology, but most drones use electric motors to power their rotors—and these motors run fairly quietly!

Despite being small and compact enough that they can be operated indoors without too much difficulty (assuming there’s adequate space available), many models buzz around almost silently while they are flying around above your head or out in front at some distant location.

Noise Pollution Due To Drones And Helicopters

If you’re one of the unlucky people living near an airport, you might think so. When drones and helicopters fly overhead, they make loud, whirring noises that can be heard both indoors and out. Residences near airports are subject to these sounds all day long because pilots are constantly taking off and landing at these fixed locations.

Sleep deprivation is a common side effect of noise pollution. Many scientific studies have found links between sleep loss and certain health problems, including cardiovascular diseases (e.g., heart attacks) and psychiatric disorders (e.g., depression).

People who live in areas with high noise levels often report feeling stressed out by their surroundings—and stress has even more far-reaching consequences for our physical well-being than sleep does!

Noise pollution from aircrafts harms our mental health as well as our physical health; it’s important to recognize that this problem must be addressed if we want to improve quality of life for humans all over the world.”

Drone Sounds Depend On Its Speed

As with all aircraft, there are many factors that determine how much noise a drone makes—not the least of which is the speed at which it flies. The faster a moving object travels, the more friction it experiences when it moves through the air.

In this case, the more friction that occurs means that the propeller blades need to produce enough power to overcome the force of drag (which acts in opposition to forward motion). More power means larger rotors and stronger motors—and thus, louder noises.

With all things being equal, let’s say you’re flying two drones of identical weight at different speeds—one going fast and one going slow. The high-speed drone would likely be louder than its slower counterpart due to its increased production of thrust.

However, this is not always true for every drone: for example, some drones are designed with quieter propellers specifically for those who want to fly without making a lot of noise.

Drones Can Fly Higher Than Helicopters

To start, drones can fly quieter than helicopters. Drones can also fly higher, longer and faster than helicopters. Finally, drones are more precise in their movements than helicopters because they are controlled by a human operator and not a pilot who is physically in the helicopter.

Frequently Asked Question (do Drones Sound Like Helicopters)

What Kind Of Noise Does A Drone Make?

Answer. The rise of drones has been accompanied by a rise in complaints about the buzz they make. Some say that the noises made by these flying robots are irritating, while others say that they are downright annoying.

In fact, there have been reports of many people who have been irritated to the point of taking action against their neighbors for flying drones over their homes or near their property.

Can You Hear Drones?

Answer. Drones are noisy, right? Not always. The noise you hear is a function of the motors and the propellers. Small consumer drones generally have four propellers and two motors, each with its own propeller. If one motor is spinning faster or slower than the others, it can make a buzzing sound that gets louder as it gets faster (or quieter as it slows down).

How Do You Tell If A Police Drone Is Watching You?

Answer. Drones can be a useful tool for police work. They can help locate runaway suspects and lost children in remote or dangerous areas without putting officers at risk or allowing a suspect to escape.

But they also raise privacy concerns — especially when they carry video recording devices. When is it appropriate for police to use drones? And how can you tell if one is watching you?

How Do You Spot A Drone At Night?

Answer. Look for red flashing lights or a red spotlight. Many drones have red flashing lights or a red spotlight that makes them easy to spot at night. Follow the light and you’ll find the drone.

Listen for the buzzing sound of a drone motor overhead and look up. Drones may not be easily visible at night, but their motors make noise similar to an electric razor, so listen closely and then look up. 

What Makes Drones So Noisy?

The drones you hear are powered by propellers. Propellers are great because they allow the drone to move quickly and fly high. But they also produce sound waves when they move air around, which is why you can hear them so well.

A typical drone has two propellers on each side of its body, and they spin at high speeds to provide lift and propulsion. If a drone were to fly at low speeds or hover in place, you probably wouldn’t be able to hear it anywhere near as well as if it were flying fast or high up in the air (like over your house).

Are Drones Really That Loud?

Drones are measured in decibels, which is a measure of the volume of sound. In general, the lower the number, the quieter it is—a whisper is about 30 dB and a car engine is about 90 dB. Drones usually hover around 80 to 100 dB. That’s comparable to standing next to a vacuum cleaner or riding in an airplane—not as loud as some people might imagine (but still loud enough that you may want earplugs). If you fly your drone for longer periods of time with no breaks between flights, you’ll probably need hearing protection.

If you’d like to keep your ears safe while flying but don’t want to spend more money on purchasing high-end drones that are already fairly quiet, there are several ways you can reduce noise pollution:

How Can I Make My Drone Quieter?

There are many factors that determine how quiet or noisy a drone will be, but these are the most common ways to reduce noise:

  • Use a lower-pitched propeller.
  • Use a quieter motor.
  • Use a smaller battery and/or lower voltage batteries (1400mAh instead of 1500mAh). This can reduce sound by up to 5dB at full throttle because less power is being consumed, which means less heat produced and less cooling required. Also consider reducing the size of your battery pack if you have space available on your frame; this will help keep things quiet overall since there won’t be as much air displacement behind the propellers while they’re spinning at high speeds!
  • Lighten up your frame material—carbon fiber makes for great strength but also makes things very heavy! Aluminum is much more lightweight without sacrificing durability in most cases; consider using it instead of carbon fiber if weight savings are important for what kinds of missions you’ll be accomplishing with your new drone.”

How Much Do Quieter Drones Cost?

If you are looking for a quieter drone, the price of a drone increases with its size. For example, a larger drone will cost more than a smaller one. Larger drones can be used for more applications and therefore have higher costs associated with them.

Drones also tend to be made of better quality materials when they are designed to be quieter than their louder counterparts. This means that there may be higher costs associated with these materials, which need not be included in some cheaper models that don’t have as much emphasis on quietness or quality construction materials like carbon fiber or aluminum framing instead of plastic parts like most regular drones use today!

Where Can I Buy A Quieter Drone?

If you’re looking for a quieter drone, there are several options. You can purchase one from brands that manufacture drones with lower noise levels. If you want to go the DIY route, there are some tutorials on how to do that as well.

If you decide to purchase a drone from Amazon or eBay, make sure it’s made by a reputable brand so that at least if something goes wrong or breaks over time, customer service will be available should something happen and someone needs help fixing it fast!


Drones and helicopters are both flying machines that use blades to generate lift and propel themselves through the air. Helicopters are generally larger than drones, but the two types of aircraft have a lot in common when it comes to how they move through the air.

The conclusion of this article is that the sounds made by a drone and a helicopter are fundamentally different, so distinguishing between them is easy. While any object could create sound, drones are quieter than helicopters. This is because helicopters need to slow down air vortices to remain airborne without extra power.

Drones are not helicopters. Drones are lighter and quieter than helicopters. If drone owners are worried about the noise their drone makes, they can consider buying a pair of ear defenders or other similar devices to reduce the sound impact when they fly.
