Simple Son to dB Calculator (with 0.3, 1.5, 3.0 Son Examples)

Loudness is measured in decibels, isn’t it? Most of us are familiar with decibels (dB) when describing how loud something is. So we may be surprised when we see the noise level expressing ‘sons’, we have prepared a Sons to dB calculator to help you.

To convert Sons to dB, we use the following equation:

dB = 33.2 × log 10 (sons) + 28

Do not worry; You don’t have to use it. We have designed a Sons to dB calculator (found below) Which automatically converts any amount of gold into decibels. This can come in handy when you’re figuring out what Sons means to fans.

Example: A bathroom exhaust fan has a noise level of 1 Son. How many decibels in 1 son? 1 gold is equal to 28 dB,

In addition, you will also find the Sons calculated for the dB chart 0.1 to 20 son, On top of that, we have solved 3 examples how to convert Sons to dB, namely:

  • 0.3 Sone to dB (Example 1).
  • 1.5 Sone to dB (Example 2).
  • 3.0 Sone to dB (Example 3).

Before we look at the Sons to dB calculator, charts, and examples, let’s explain what Sones really are, where they come from, and why we don’t use decibels to measure sound:

What are Sons? How Do Sons Compare to Decibels?

Decibel is our standard unit of measurement for sound. Technically, a decibel is a relative unit equal to one tenth of a bel. However, the decibels are a bit hard to imagine.

1936, American psychologist Stanley Smith Stevens In the study of psychoacoustics, a new unit – Sons – was proposed. Sons are basically loudness units that express the perceived loudness of sounds; How loud do we feel some noise.

are here Loudness Intensity of 1 to 10 Son Sounds:

  • 1 son is the sound of an average refrigerator.
  • 2 Sons is a quiet office sound.
  • The 3 Sones is a sound TV makes when set to a comfortable volume.
  • How loud is normal 4 Sons talking?
  • 5 Sons is basically one loud conversation.
  • 6 Sons equals sound in a quiet restaurant.
  • 7 Sons is a sound we hear on a quiet traffic street.
  • 8 Son is a sound that we hear on an average high traffic road.
  • 9-10 Sons is the sound of a busy traffic street.

Now, the son is not as popular a unit of loudness as the decibel. Nevertheless, the loudness of some HVAC products such as fans is usually measured in sones. For example, many people ask us ‘What is gold in fans?’.

We explain to them that sonnet is a unit of loudness and can be converted into decibels. Here is the mathematical formula we use to convert Sons to dB:

dB = 33.2 × log 10 (sons) + 28

The Sons to dB equation is not the easiest to use. To help everyone else out, we’ve designed a calculator that uses this Sones to dB formula to calculate Sones to dB. Here is the calculator:

Sons to dB calculator (insert sones, get dB)

You can try this example: Check how many dB is 0.5 sone.

Use the slider and slide it to 0.5. You will get result: 18.005804143955825 dB. This means that 0.5 Son is equal to 18 dB.

You can use this Sons to Decibel calculator to convert any Sons to dB. To help you out, we’ve calculated some of the most common sone in fans and converted them to dB. Here are the results, summarized in one chart:

Let us solve 3 examples to explain how SOON to DB conversion works:

0.3 Son to dB (Example 1)

Some of the quietest fans only operate at noise levels of 0.3 Son. How much is 0.3 sone in decibel?

We use the dB equation from Sonne:

dB = 33.2 × log 10 (son) + 28

We just put 0.3 where the ‘sons’ are and use a handheld calculator to get the result:

dB (0.3 Son) = 33.2×log10(0.3) + 28 = 10.64 dB

This means that 0.3 Son is equal to 10.64 dB. Even our ears will not be able to hear such a slow sound.

1.5 Sone to dB (Example 2)

Let’s say we have a bathroom exhaust fan that runs on 1.5 Sons. We would like to answer how many dB are 1.5 Sons. To calculate this, we simply use the Son to dB formula and repeat the process like this:

dB (1.5 Son) = 33.2×log10(1.5) + 28 = 33.85 dB

We have our answer:

1.5 Son is equal to 33.85 dB.

3 Sone to dB (Example 3)

You can use this same process to convert Sons to dB for any number of Sons. To make it even clearer, let’s calculate how many dB equals 3 Sons:

dB (3 sons) = 33.2×log10(3) + 28 = 43.84 dB

here you have it:

3 gold is equal to 43.74 dB. It is a voice that we can hear quite easily.

We used the Sons to dB conversion in our article about the best bathroom exhaust fans (you can check it out here). You’ll see how you can compare fans spec-by-spec, including comparing noise levels.

We hope this helps. If you have any questions or want us to help you with this conversion, you can use the comments below and we’ll try to solve it together.
