Why Are Hand Dryers So Loud? (EXPLAINED!!)

Hand Dryers are one of the most important tools in any restroom. They save paper towel usage and help to keep the environment clean. Even though hand dryers play an important role in our daily lives, they can be quite noisy. But why are hand dryers so loud?

Hand dryers are so loud because they work by using a high-powered motor to force air through a small opening. This airflow creates turbulence which amplifies the sound of the hand dryer. In addition, hand dryers are often located in areas with hard surfaces such as tile which can further amplify the sound. Finally, many people use hand dryers when they are already in a hurry which can increase their perception of the noise.

How Loud are Hand Dryers?

You might be surprised to learn that hand dryers are actually quite loud. In fact, they can reach up to 85 decibels, which is about as loud as a blender or a vacuum cleaner.

Of course, not all hand dryers are this loud, but it’s definitely something to keep in mind if you’re looking for a quiet option.

According to tests the average hand dryer is around 80 decibels, which is about as loud as a blender. Some hand dryers can be even louder than that, reaching up to 100 decibels.

It’s important to note that noise above 100 decibels can cause noise induced hearing loss even when exposed for less than 15 minutes daily.

That’s about as loud as a chainsaw. Thankfully, most hand dryers have an automatic shut-off feature so they don’t run for too long and damage your hearing.

So why are hand dryers so loud? It’s because of the way they work. Hand dryers use a powerful stream of air to quickly dry your hands.

This high-speed airflow makes a lot of noise as it exits the dryer. Some hand dryers are louder than others because of the type of motor they use.

Brushless motors tend to be quieter than standard motors, so if you’re looking for a quiet hand dryer, make sure to check for this feature.

If you’re not a fan of loud noises, you may want to avoid using hand dryers altogether. You can always opt for paper towels instead.

Or, if you’re at a public restroom that only has hand dryers, try covering your ears with your hands while the dryer is running. Either way, it’s important to be aware of how loud hand dryers can be so you can protect your hearing.

Factors to Consider When Buying A Hand Dryer

 When choosing a hand dryer, there are several factors you need to consider to ensure you select the best possible option for your needs. Here are four key considerations:

1. Power Source: Hand dryers can be either electrically powered or battery powered. If you plan on using your hand dryer in a location where there is no electricity available, then you will need to choose a battery-powered model.

2. Drying Time: The drying time of a hand dryer is an important consideration, especially if you have a large number of people using the device on a regular basis. Some hand dryers can take up to 30 seconds to completely dry your hands, while others may only take 10-15 seconds.

3. Noise Level: Another important consideration is the noise level of the hand dryer. Some models can be quite loud, which may not be ideal if you are using the device in a public space such as a office or store.

4. Price: Hand dryers can vary significantly in price, so it is important to consider your budget when choosing a model. Some high-end models can cost upwards of $100, while more basic models may only cost around $20.

5. Warranty: Finally, you’ll want to consider the warranty that is offered on the hand dryer. Most models come with a one-year warranty, but some may offer longer terms. This is important to consider in case you have any issues with the device within the warranty period.
