Explained: Blender Noise Factors


Blenders may seem like a relatively simple home appliance, but they can be surprisingly loud. This is especially true if you’re using a high-powered blender that’s designed to pulverize ice and other hard ingredients. Here’s why your blender is so loud, along with some tips on how to reduce the noise level:

Why blenders are so loud

Blenders are loud because they use a fast-moving blade to mix the contents of your drink. The speed of this blade causes the air around it to move at high speeds, creating a vacuum behind it as it moves forward. This is called an “audible” vacuum and air rushes in to fill that space.

When you turn on your blender or food processor (or any other appliance with similar functionality), there’s going to be noise–but don’t worry about being too loud for your neighbors!

What makes a blender so loud

There are a few things that make blenders loud. Let’s look at each one in turn:

  • The blender blades are the most obvious culprit, and they’re also probably the most important part of the machine. They’re what does all of the work when you blend something, so it makes sense that they’d be loud! If you’ve ever tried to use a handheld mixer or food processor, then you know how loud these can be–and those devices don’t have nearly as many blades as your average blender does! So if you want to reduce noise levels from your kitchen appliances (especially if there are other people living with you), consider getting an immersion blender instead of buying another traditional model.
  • Next up is obviously going to be whatever kind of motor powers those blades; this could either mean using an electric motor or relying on manual labor instead (like pushing down buttons). For example: if someone has given us one cupful of fruit juice but we want more than two cups’ worth–what should we do? Well firstly make sure

How to reduce the noise of your blender

  • Use a blender cover. You can buy one or make your own, but either way it will help to reduce the noise of your blender.
  • Use a glass jar instead of plastic or steel. Glass jars are much quieter than their counterparts because they don’t vibrate as much when they’re in use.
  • Set your speed setting lower than usual if possible (and remember that high speeds aren’t always necessary). In general, low speeds are better for smoothies because they prevent chunks from forming on top and getting stuck in blades over time–and this is especially true for blenders with smaller motors!
  • If all else fails and you still need more power than what’s available at low speeds, consider investing in a tamper tool like The Boss Tamer from Blendtec so that no matter how thickly packed your ingredients get inside its chamber during blending time there won’t be any chance whatsoever for clogs due to lackadaisical blending techniques like those mentioned above…

Blenders are noisy, but there are ways to make them less so.

You may not realize it, but blenders are actually louder than you think. Why? Because of the way they work.

Blenders use blades to chop up food and blend it into a smooth consistency. The more powerful your blender is (i.e., the more watts), the faster those blades will spin–and thus make more noise!

There are two ways to reduce your blender’s sound: one involves changing how much power you put into it; another involves changing how long you use it for at once. If you want less noise from your blending experience, try blending at lower speeds or for shorter periods of time with each pulse cycle.


Blenders are a great tool for making smoothies and other drinks, but they can be loud. Fortunately, there are ways to reduce the noise that your blender makes. If you’re looking for a quieter blender, check out our guide on how to find one!
