How Many Decibels is a Vacuum Cleaner?

Vacuum cleaners have made millions of lives easy by helping with the daily chores. A large room that would otherwise require several hours of cleaning can become shiny in under 30-minutes if you use a vacuum. However, the powerful suction motors of the vacuums can sometimes be very loud and may disturb others. In this regard, people keep searching on the internet ‘How many decibels is a vacuum cleaner?’. If you find yourself puzzled about the sound a vacuum cleaner makes, this article is for you.

How Many Decibels is a Vacuum Cleaner

The human ears can pick sounds between 0dB (threshold) to 130dB. However, prolonged exposure to high decibels can cause severe damage to your hearing and may even lead to permanent deafness. Fortunately, vacuum cleaners produce noise well within safe limits. Still, some people find the vacuum noise very annoying as it disturbs their focus. Here are a few examples of the noise of different scenarios:

  • 0 The softest sound a person can hear with normal hearing
  • 10 normal breathing
  • 20 whispering at 5 feet
  • 30 soft whisper
  • 50 rainfall
  • 60 normal conversation
  • 110 shouting in the ear
  • 120 thunder

Usually, vacuum cleaner decibels levels are between 65 and 85 decibel sound. As a result, people are always looking for new products that cause as little noise pollution as possible. Still, it is a known fact that vacuum cleaners can never be completely silent. So, manufacturers are actively working to develop new ways to suppress the noise. Some examples of sound produced by everyday household appliances:

  • 60-85 Vacuum Cleaner
  • 65-80 Alarm Clock
  • 60 Sewing Machine
  • 60-95 Hair Dryer
  • 55-70 Dishwasher
  • 50-80 Electric Shaver
  • 55 Coffee Percolator
  • 50-75 Washing Machine
  • 50-75 Air Conditioner
  • 50-60 Electric Toothbrush
  • 50 Refrigerator

According to scientists, prolonged exposure to 70dB or more sound can impact your health. So, it would be best to choose a vacuum whose noise level stays well below this limit.

How Many Decibels is a Vacuum Cleaner? How to Check?

Major vacuum brands like Dyson actively test their new products before releasing them in the market. The series of tests includes the durability test, efficiency test, suction power, weight test, and how many decibels is the sound of a vacuum cleaner. Manufacturers use advanced decibel meters to check the lowest and highest level of noise produced by the device under different conditions.

The main goal of any brand is to provide a device that provides maximum performance without compromising the noise discipline. In this regard, the robotic vacuum cleaners and some uprights produce the least noise, even in turbo mode. You can always check the decibels of your vacuum cleaner by studying the user manual and specifications chart. If the information is not provided with the package, you can always check the product website for more information.

Lastly, you can take matters into your own hands and use a sound meter. The easiest way to use a sound meter is to download an app on your smartphone. Turn the vacuum on, switch to maximum performance, and start testing. It is best to note at least three measurements for each mode, the average of these values will be the decibels of your vacuum cleaner.

What if the vacuum starts producing more noise than normal?

A vacuum cleaner is a machine that uses different motors and systems to provide the most effective way to clean your house. Like other machines, a vacuum cleaner is also prone to wear and tear. If you face a situation where the vacuum cleaner starts producing more noise than the first time, there may be something wrong with the device. Here’s how you can troubleshoot the problem:

Physical damage:

How many decibels is a quiet vacuum cleaner? Well, that depends on how well it is sealed. Usually, vacuum cleaners are protected with an air-tight casing that prevents any leakage of dust, air, and sound. However, if the case is physically damaged or if the seal is broken, the vacuum will start to produce more noise. So, the first thing you should do is physically inspect the device and look for any signs of damage. If you find any holes or damage, seal it with an adhesive solution, duct tape, or take it to the nearest service center.

Filter damage:

Modern vacuum cleaners come with an advanced HEPA filter. Every bit of air sucked by the vacuum passes through this filter to remove the fine dust particles. However, the filter gets clogged over time if you don’t clean it regularly. As a result, the vacuum cleaner has to work harder, leading to more noise production. Moreover, you may even burn the suction motor due to overheating if you don’t act fast enough. So, the second step of troubleshooting is to clean the filters with clean water, a blower, and alcohol.

90% of the time, cleaning the filter instantly fixes the noise problem. So, don’t skip this step at any cost.

Check the air passage:

The suction motor of a vacuum cleaner automatically produces the power required to suck the air. Therefore, every component of the air passage needs to be clean for optimum performance. However, sometimes your vacuum cleaner’s hose may get clogged with plastic, wrappers, pencils, and other large objects. Therefore, it would be best to examine the vacuum’s hose and remove anything that is stuck in it.

Similarly, the vacuum fan is another spot where debris may collect with the passage of time. It is recommended to clean the fans every now and then to keep your vacuum cleaner in optimal performance. You can clean the fan by removing any solids stuck in it, and don’t forget to use a blower to remove the dirt.


Vacuum cleaners are the most important cleaning equipment for both residential and commercial spaces. However, the noise produced by the vacuum cleaner is very annoying and may even cause damage to your hearing. Millions of online searches target the question ‘How many decibels is a vacuum cleaner?’ This article provides a comprehensive answer to that question and also provides ways to reduce the noise of your vacuum cleaner.
