How Many Sones Is A Quiet Bathroom Fan
A quiet fan is subjective since the noise level is measured mostly by the loudness of the fan and depends on your tolerance to noise. This leads to different views regarding the number of sones that make a quiet bathroom fan.
Since many modern bathroom fans are almost unnoticeable when turned on, it can become quite difficult to point out the loudness of the exhaust fan.
In most cases, a bathroom fan is considered quiet when it is around one sone and less. And the quietest bathroom fan exhaust is below 0.5 sones. For instance, the quietest fan on the market in [year] is 0.3 sones (Broan-NuTone QTXE080) which runs calmly and is unnoticeable. If you need a more powerful fan, 0.8 sones is still quiet and good for even large bathrooms (Panasonic FV-0811VF5 WhisperFit).
What Is Considered A Quiet Bathroom Fan
Bathroom fans are different, and depending on the manufacturer; you’ll get different features that make the bathroom fan quiet. For this case, a bathroom fan is considered quiet when the loudness is impossible to hear. With this, you can set it in the bathroom and run it silently.
The magnitude of loudness is rated on a system called sones, and the smaller the number of sones, the quieter it is. In most cases, quiet bathroom fans are 0.5 sones and below.
These are almost silent, and users might doubt whether it is working or not. A working fridge will have one sone, and when compared to the fan at 0.5 sones, you can imagine the low noise levels.
Bathroom Fan Sone Scale
The loudness of fan noise is measured in sones, and a sone scale will help get the correct loudness for your specific fan. Commonly, the sones scale system has numbers indicated on the fan box.
The numbers might be larger or smaller depending on the fan and the size of the exhaust. Commonly, a large number indicates a loud fan.
For example, a fan on a scale system of 4 sones and beyond means it is loud, and when in a hallway, you can hear its sound.
Fans under one sone on the sone scale are considered quiet. The lower the number, the quieter the fan.
What Are Sones In Bath Fans?
Bath fans are rated in sones, and this sound is based on how an individual’s average listener perceives it. Most home appliances like fridges, range hoods and washing machines will have different ratings on how loud they function.
These are also measured in sones. To compare the sone bathroom fan, we can take the average noise of a refrigerator estimated at one sone.
If you double that noise to two sones, then the sound becomes louder. Therefore, the loudness in the bath fan is measured using the sones rating system. Read also: Best Quiet Bathroom Exhaust Fans With LED Light, Heater & Both and Best Most Quiet Or Silent Battery Operated Toothbrushes [year]
