Use Of Sones In A Range Hood

A sone measures loudness. What does it mean? It measures the noise level of a kitchen fan. The sone rating of a range hood is proportional to its loudness. The Use of Sones In A Range Hood Will be discussed further in this article.

Due to the loud noise of the kitchen exhaust fan, people avoid buying range hood. But as we know along with disadvantages there come some advantages so range hood also has some advantages and we should focus on it and decide whether to buy it or not. 

Few are reasons listed below where one should focus on why to buy range hood:

  • It disposes of the steam and moisture that is caused by cooking which leads to fungal growth.
  • It protects from the harmful toxins released in the kitchen while cooking and thus leading a healthy life.
  • It also provides bright light.
  • It helps in eliminating excess heat produced in the kitchen and keep it cool.
  • It also helps to get rid of unpleasant smell released from the kitchen keeping the air fresh.

Maybe after knowing the benefits of range hood, many of you would like to buy it. But you need to consider the best quality of rangehood as it will be used in the kitchen where safety is the most important aspect to look after. So, you must be thinking what do we need to consider here? The simple answer is we need to check the CFM and sones rating. 

What Is CFM?

So you must be wondering what is CFM (Cubic feet per minute). This refers to what number of cubic feet of air the hood is debilitating each minute at maximum speed. It measures your rangehood performance. More CFM eliminates the extra heat and toxins from the air produced in the kitchen.
The ventilation power in the kitchen depends on the range type, kitchen size, cooking schedules, and ductwork.


Electric: The standard for deciding the base CFM for electric reaches is controlled by the width of your range. By and large, you need about 100 CFM for each 10″ width of your electric range.

Gas: Gas ranges produce much more heat and exhaust contrasted with an electric range so their CFM requests are higher. The measure of heat discharged from a gas cooktop is estimated in British thermal units (BTUs). It is the amount of heat required to raise the temperature of a pound of water by one degree Fahrenheit.


The size of the kitchen affects the amount of CFM you need. If your kitchen size is large, you will need more ventilation power. 

So, first, measure the volume of your kitchen and then calculate the CFM using the formula: length*width*height*15 /60. Here 15 is the air exchange times per hour. and 60 is used as minutes per hour.

Or, you can simply use the formula: length*breadth*height/4. You will get the same answer. 

Next, calculate the CFM necessities for your cooktop and contrast that with the number you determined for the volume of your kitchen.

Finally, take the bigger number and use it as the base CFM prerequisite for your new vent hood as you shop.


Your habits in the kitchen can impact whether you decide on a higher CFM kitchen exhaust fan. Ask yourself a couple of questions to make sense of what sort of schedules you have and whether your one of a kind cooking circumstance requires all the more remarkable ventilation.

  • Like, how often do you cook? Do you cook on your cooktops? or, Do you use all the burners at once?
  • What type of food do you often cook?
  • What is your style of cooking? 


Your range hood’s ducting will significantly affect your CFM needs. On the off chance that you are building another kitchen, you can plan to introduce the correct ducting for the kitchen to extend your pick. 

In any case, if your ducting is now set up and you don’t anticipate altering it, you’ll need to check out your ducting before choosing what number of CFM you need. 

Consider the ducting’s length, shape, size, and goes turns to help you out to the amount CFM you’ll require.

A decent general guideline for evaluating duct diameter and CFM requirements is:

  • 6″ to 8″ duct = 400 to 600 CFM
  • 7″ to 10″ duct = 700 to 900 CFM
  • 8″ to 12″ duct = 900 to 1200 CFM
  • 10″ and up duct = 1200 and higher CFM

Here is a formula to help you find out the CFM based on your ducting: 

  • For each foot of piping length, increase your CFM by 1.
  • For each turn in your piping, increase your CFM by 25.
  • If you have a roof cap, increase your CFM by 40.

Now, to calculate the CFM of a range hood, take the highest rating between the output of your burners, or the volume of your kitchen and add the requirements from your ductwork calculations. 

Usually, a higher CFM is ideal as it keeps air clean and fresh by allowing you to cook different varieties of food, and also you can use it at a lower speed. You won’t regret buying a higher CFM.

Keep in mind, you will only be able to maximize the CFM of your hood if your kitchen size is according to the size of your range.


Choosing what sone level is suitable relies upon your inclinations and how you intend to utilize your kitchen exhaust fan. The Use of Sones in a Range Hood will be discussed below!

Proline range hoods have both four and six speeds and each speed compares to a different sone level. We can also say speed is directly proportional to sound. If speed is higher, the range hood sound is more and if the speed is lower, the range hood sound is less. 

Here we will compare the sone levels with sounds we are familiar with.

  • Sone 1 loudness: sound like a running refrigerator
  • Sone 2 loudness: sound as if it’s a clam office
  • Sone 3 loudness: sound like a radio playing at the comfortable volume level
  • Sone 4 loudness: sound like you’re having a normal conversation
  • Sone 5 loudness: sound like a normal conversation with extra noise
  • Sone 6 loudness: sound like quiet restaurants
  • Sone 7 loudness: sound like traffic lights
  • Sone 8 loudness: sound like regular traffic 

I hope the above comparison made you clearly understand the CFM and sone ratings.


So, search for a powerful range hood with a higher CFM rating and movable speed settings, so you might have the option to change the sound. Along these lines, you may ensure your house is perfect, safe, and unwinding.
