Why are Blenders So Loud? How to reduce their noise?

Your blender’s noise can wake your kids and the neighbors’ dog; it’s mostly THAT loud. Using a blender without that whirring sound is something most cooks wish for. But why is it so? Do all blenders make noise, or does yours has some fault?

If you are confused about any of these questions, we will answer them. We have listed the possible reasons and solutions for your blender’s noise; let’s take a look.

Why are Blenders So Loud?

Blenders are powerful kitchen appliances that run at a fast speed and use a significant amount of electricity. When a blender’s blades grind against each other, they create a vibration that translates to noise. The way your blender works is why it is so noisy; its electric parts are bound to vibrate and be loud. Another important reason behind this problem is the food you are blending. If you crush nuts or ice in a blender, it will be louder than making a vegetable smoothie.

Blenders are loud because several small electric and metal parts move around together while you are grinding something. This puts a significant load on your machine and affects its functionality.

A blender’s average RPM is 15000 to 25000, which is quite powerful given the size of these appliances. When a machine runs this fast, all parts are in motion and are supposed to be noisy. But your blender’s speed is not the only reason it creates so much noise; here are a few other factors that can impact its sound:

Blender Motors

Blender motors require a consistent and significant electricity supply to grind your food. And when electricity moves a blender’s magnetic and metal parts, it creates around 80 DB of sound, which is quite noisy.

Rotations per Minute

Most blenders have 15000-25000 rotations per minute, making their steel blades move around at an unbelievably high speed. Now, even if these are soft and polished blades, they will create vibration. And given that blenders have hardened steel blades, you can imagine the level of noise they’ll make.

The food you’re blending

What do you usually blend? Is it nuts, vegetables, or ice for smoothies? The answer to this question will impact your experience with a blender’s sound.

Hard foods like nuts and dry fruits create more friction with a blender’s blades, eventually making more noise.

On the flip side, vegetables and fruits go easy on these blades and don’t generate unbearable sounds.

Material quality

Low-quality blenders have plastic bodies and unpolished blades that impact your experience with them. If you purchase the blender from some random manufacturer to save a few bucks, be ready to face the consequences.

High-end appliance manufacturers have reliable motors and better quality blades that don’t require you to soundproof the kitchen while blending something.

Apart from these major reasons, your blender’s condition can also be the reason for its noise. If you have a pretty old blender that is getting louder by the day, its bearings and motor brushes might have worn out. Get it checked to rule out these reasons.

Are blenders too loud for apartments?

Yes, blenders are too loud for apartments and condos because these units are interconnected, and the noise might create an echo. If your kitchen has thin walls or you place the blender in front of a window, you are likely to disturb the neighbors. If you live in an apartment and use the blender regularly, get a quieter one or work on soundproofing the existing one.

Blenders are noisy; no argument about that. Whether you have a new one or have been using it for years, its motor and blades will create noise when in use.

People living in apartments particularly struggle with loud appliances because their neighbors and even family members are disturbed by them.

But this is not a lost cause, as you can pretty much soundproof a blender by following some easy hacks.

How to reduce Blender Noice to make it quieter?

If your blender has become too loud to bear, don’t lose hope because there are still a few ways to help you through this. Here are a few tips that will help you make your blender quieter:

Place the Blender on a Steady Surface

When a blender is placed on an uneven surface, it strikes against it and creates an echo. Therefore, start placing your blender on a steady surface like a granite countertop or a stable wooden floor.

Cushion the Surface Under your Blender

Cushioning the surface under a blender will reduce its sound and vibration. If your blender usually sits on a hollow or thin surface, try placing a mat under it.

Using a silicone mat, kitchen towel, or cotton cloth will absorb the noise coming out of your blender.

But remember not to block the blender’s ventilation while doing so. Blocked ventilation will overheat your blender and reduce its working capacity.

Remove the Echo Effect

If your blender is surrounded by hard surfaces like the countertop under it and the walls around it, running it will generate a significant amount of echo.

Move your blender away from the wall and surround it with a soft surface like cardboard or a silicone mat to reduce echo.

Can blenders cause hearing loss?

Blenders generate 60 to 80 DB of sound on average, which is not damaging to your hearing.

However, if a blender’s noise exceeds 80 DB, which is common for the powerful ones, it can impact your hearing ability. Especially if you have kids around, a blender’s noise can be disturbing.

We recommend using earplugs or moving away when the blender is on. If you follow the tips we have shared above, you can overrule this problem.

Final thoughts

Blenders can be unbelievably loud sometimes. If your blender is of low quality or has been used for years, its bearings weaken and create a significant amount of noise.

The main reason your blender generates such a disturbing sound is its RPM, which puts its motor through a lot of work in a short duration.

If your blender’s blades are worn out, they produce friction, resulting in noise. But when you place the blender on a study surface and use an absorbent material like a silicone mat, you can overcome this problem.

Protect your hearing by using earplugs or moving away from the blender if it gets too noisy. If nothing from our above-listed reasons feels valid, check with the blender manufacturer to know what they say about it.

Sometimes the only thing wrong with an appliance is the time it has spent in your home. Advanced blenders are quieter and easier to handle; if you have the budget, go for a better appliance.
