Why are Blenders So Loud?

Have you ever been in the kitchen, doing your best to prepare dinner for your family, and all of the sudden a blender comes on like a jet engine? The sound can be so loud it makes you jump and makes it nearly impossible to hear yourself talk.

Some blenders come with noise-canceling features that make them quieter while using them, but these work much less well than when they’re not in use. but most standard blenders are really loud and this article aims to shed a light on blender noise levels.

why are blenders so loud?

1. Steel Blender Blades:

Steel blades are pretty common in most blenders these days. The problem is, steel is very abrasive. Blender manufacturers have done much to mitigate this, by giving blenders softer and longer blades to use instead of steel. However, the back and forth motion of the blades does still fairly closely resemble grinding. This grinds away at everything inside your blender, especially your motor.

2. Blender Motor:

In order to make a blender spin, you need to provide power to the motor pulley. This is done via a belt and pulley system. The most common speed of a blender is around 50-100 RPMs (rotations per minute.) A high-quality stand mixer on its fastest speed goes about 250 RPMs, or they go even higher for dough. Electric motors are very mechanical parts that require the use of electromagnets in order to work properly. The stronger the magnet, the more power it takes to get an electric motor spinning, and there louder it is.

3. High Speeds:

No matter what you’re making in your blender, it’s always going to need to be turned on for the same amount of time. This means you have a lot of blending time with the motor running at high speeds. The blades are also used with the same amount of force in order to grind even the hardest ingredients into a powdery consistency. They’re spinning so fast and applying so much force that they’re practically crushing everything inside your blender.

4. High RPM required by Blender:

Most blenders come equipped with a blend component in order to grind things. Depending on the brand of blender, these machines can require speeds of up to 2,500 RPMs (double the speed of a conventional stand mixer.) This is where your motor really starts to heat up and break down. This causes even more strain on your motor and that makes the blender more loud.

5. Most are Cheaply Made:

Most blenders are made to such a low-quality standard that they’re prone to breaking any day, even when just used for blending. You can buy a blender in minutes for as little as $30, Cheaper blenders are louder because they’re usually made from cheap plastic and metal. The good thing is that you can find some really nice quality blenders that are quieter but they come at a premium.

Are blenders supposed to be loud?

Standard blender noise comes from the fact that they’re making a lot of fast, strong noise. However, some blenders come with more features that do a great job at mitigating the sound and keeping them more quiet. It all depends on the kind of blender you choose to purchase. If you’re in the market for a blender or are simply curious about what some of the quieter models have to offer, keep reading for everything you need to know about finding a quieter blender:

Are there Quiet Blenders?

If you’re looking to purchase a better and quieter blender, you’ll first need to consider your budget. You can always spend $200+ on a high-end blender with all of the bells and whistles, but it’s important to know that most of these blenders will look shiny and nice, but they won’t necessarily be any quieter than a standard option. Really quiet blenders come at a premium but they’re also made better and for people who know what they’re doing.

The first thing to look for in a quieter blender is the type of material it’s made out of. Really quiet blenders are typically made from stainless steel or, even better, aluminum. The reason why these materials are preferred is that they don’t get as hot and can withstand high speeds without overheating as a cheaper plastic blender would like. One quiet blender that I recommend is the Quiet One by Vitamix.

Final Thoughts on Why Blenders are Loud

The reason why blenders are so loud is that they’re made out of steel and have heavy-duty blades. This makes them very abrasive and grinds away at the motor the more time it’s used. You’ll also notice that a lot of blender motors are more powerful than regular stand mixers which causes them to heat up much quicker.

All in all, it’s important to use your blender wisely and for the right amount of time because it will be able to last you for a long time, rather than breaking after one or two uses.
