Hand dryers can be very loud, young children often cannot bear the sound. In fact, the Canadian Paediatric Society confirmed that hand dryer noise is dangerous to young children.
But why are hand dryers so loud?
Old and new hand dryers both use motors and fans.
Once hand motion is detected by the sensors, the motor forces airflow from narrow bezels along with the heat to blow water off the skin’s surface, this whole process requires a lot of power which means the motors create a lot of noise as they force the air out.
The noise of hand dryers can surpass 100dB which is dangerous to children.
One of the problems with newer quicker drying hand dryers is that less time they take to dry your hand, the more noise they make.
How Much Noise Do Hand Dryers Actually Make?
When a teen researcher Nora Keegan measured the distance of the hand dryer from the floor and she calculated the dB output from the dyer.
70% of the dryers she tested produced over 104 dB.
This is more than the recommended noise levels for kids gadgets and toys that make sounds.
It is important to protect the children’s hearing ability, while some hand dryers produce as little as 85 dB, most common hand dryers tested produced over 100 dB.
According to reports, many hand dryers are operated at much louder than their manufacturers claimed in the user manual.
And yes, it can damage a child’s hearing. If any child is exposed to this sound level for 15 days, it could damage their hearing.

Hand dryers output may vary in different areas but as per the average measurement of dB that child and toddler can hear, we list out these hand dryers that give sounds less than 100 dB level.
In no particular order, here are some quietest hand dryers (less than 100dB).
To find the quietest hand dryer you simply need to find the machine’s power and drying speed. If the power is high and the drying speed is fast, the sound will be loud.

Factors to consider when buying a hand dryer
Choosing a hand dryer for your office or home purposes is a task that involves a lot of factors including sound, drying time, and cost.
If you are aware of the news that louder hand dryers can affect child hearing ability, you must take the sound output as a primary parameter.
Noise: Quiet hand dryers use less power for motors and fans but the drying will be longer than the other commercial hand dryers. All these listed hand dryers claimed to produce the low noise output but if you are still not sure about it, you can blindly go for the hand dryers that take less power and more drying time.
Speed: Drying speed could be the reason why people choose high-end power dryers that make louder sounds. You can also choose those hand dryers that take even 30 seconds for complete drying.
