How to Silence a Blender the SMART WAY in 2022

From my experience, I firmly believe that there are 3 main reasons why blenders are still noisy in an age where electric cars are barely audible.

They are cheaply made- spending more than $1000 on a blender may feel like a rip-off considering it’s just a simple kitchen appliance for making smoothies and some simple meal preparations.

On the other hand, most modern devices use induction motors or brushless motors, which are much quieter.

However, brushed motors a quite affordable, small, and also powerful. Unfortunately, the switching action of the commutator results in magnetic fields shifting quite rapidly, resulting in lots of banging noise.

You could use an induction motor to solve the noise problem in a blender without affecting its blending power.

Induction motors are very quiet, but to give the more torque, it’d mean creating a heavy and bulky blender.

That’s why you won’t find induction motors in anything you’ll have to lift.

To get the power and portability, you’d need brushed motors, which are pretty powerful but, unfortunately, quite loud.

Lastly, the RPMs and material being blended affect how quiet or loud a blender is.

To get finer smoothies, you need to increase speed which increases the RPM.

Nothing engineered on this planet stays quiet while spinning at more than 25000 revolutions per minute.

Crushing ice creates more noise than simply blending a banana. This directly correlates to the RPMs, more power is required to crush ice than a banana. Below are simple ways to quiet a noisy blender

1. Move The Blender Away from The Wall

Sounds waves get reflected off the walls if there isn’t good sound-absorbing material put in place.

Moving the blender away from the wall helps reduce the number of sound waves that hit the wall, reducing echoes and reverbs that make your ears perceive sound as amplified.

Something like acoustic foam panels will help absorb sound waves (echoes and reverbs) but will not block sound waves from traveling to the next room.

If you need to protect your loved ones living next room from blender noise interference, you can hang something like mass-loaded vinyl to help block both airborne and impact sound waves from escaping the room.

2. Soft Padding Beneath

Remember the reason why we added anti-vibration pads on air compressors?

Well, spinning motors produce vibrations that spread through structures and to the surrounding rooms.

Soft padding beneath the blender can significantly reduce vibrations due to the motor spinning at higher RPMs.

For example, I have had a set of Utopia Towels and would often fold one to create thick padding for my blender.

This method significantly reduced vibrations that I could previously feel whenever I placed my hand over the counter.

You can try wrapping around the motor area, and you’ll be surprised by the amount of noise you’re able to dampen.

A great alternative to the towels is a silicone mat- one of my most recommended is the Silicone Trivet Mat.

3. Try a Blender Sound Enclosure

A sound enclosure box is a simple and effective way to greatly reduce the noise your blender makes. You can either build one yourself or purchase a pre-made soundproofing box.

Whichever route you choose, make sure the box is large enough to completely enclose your blender, leaving enough room for air to circulate.

Once you have your box, line the inside with sound-absorbing material. This could be something as simple as foam sheets or blankets, or you could use specialized acoustic panels.

The more surface area covered in absorbing material, the better. To further reduce noise, seal any gaps or cracks in the box with weatherstripping or acoustic sealant. This will help to prevent sound from escaping and ensure that your blender is as quiet as possible.

A perfect example is the Whisper Blend Sound Enclosures designed by Whisper Blend.

Whether you run a smoothie joint or enjoy making smoothies at home, a sound enclosure is a perfect solution for you.

It’s available in 3 sizes to help muffle the sound of your Blendtec, Ninja, Hamilton Beach, Vitamix, and many other blenders.

• The sound enclosure boasts a patented noise absorption pad for vibrations absorption
• Comes with suction cup feet that firmly secure it to the counter hence preventing wobbling
• It’s made of long-lasting transparent ¼ inch thick acrylic that traps in noise
• Sufficient airflow that prevents the blender from overheating
• Lastly, the unit is easy to clean with a flip-top port that allows you to use a tamper or add ingredients without noise leaking out

4. Soundproof Your Kitchen

Soundproofing the kitchen will not in any way make your appliances quieter. Instead, it’ll reduce sound transmission in or out of the kitchen.

You will need to soundproof the door, windows, the floor as well as soundproof the ceiling.

Soundproofing is a time-consuming and technical activity, but it’s worthy it given that you’re able to deaden the noise from various appliances.

You won’t ever have to worry about the popping noise from your mini-fridge leaking to other rooms or worry about gas oven noises.

5. Change Blending Schedule

This may sound impossible, but it’s actually achievable, but I don’t often advocate it.

Why?

Changing the blending schedule means that you won’t enjoy your favorite fresh smoothie when you need it the most.

Some of us enjoy smoothies right of the blender jar, as it tastes great and fresh.

You can make your smoothies when no one is around or when your little one is awake and not asleep.

Additionally, you can make your smoothies during the daytime instead of late nights or early mornings.

To keep it fresh and tasty, stash it in your quiet refrigerator.

Alternatively, instead of blending for a long time at high speeds, blend for shorter periods of time at lower speeds. This will help to reduce the overall noise that your blender makes.

6. Wrap a Towel

Wet a towel and ring it out so that it’s damp, not dripping wet. Wrap the towel around the base of the blender, making sure that the blender’s blades are fully covered. The towel will help to muffle the sound of the blender as it’s running.

You can also use a dishrag or even a thick sock in place of a towel if you don’t have one handy.

If you’re using a standard blender, the easiest way to silence it is to simply wrap a towel around the base. You can also use a thick kitchen towel or even a baby blanket.

If you have a Vitamix or another high-powered blender, you may need to use something thicker, like a comforter or sleeping bag. Just make sure that whatever you use doesn’t get too close to the blades.

7. Try Earmuffs/Earplugs

If you operate a café or probably spent most of your days making smoothies, you probably are worried that blender noise could, in the long run, affect your hearing health.

Exposure to loud blender noises can indeed result in induced hearing loss- that’s according to Washington Ear, Nose & Throat (ENT) specialists. (Source)

For that reason, it would be paramount to invest in quality earmuffs or earplugs.

I have previously written a definitive guide on earplugs for sleeping– and these can be used against blender noise.

8. Buy a Quiet Blender

If you are going to use a blender regularly, it is worth investing in a quality one that will not make too much noise. Look for a model with sound-dampening technology or a rubber base to minimize vibration.

An example is the Vitamix Quiet One Blender that comes with a sound enclosure to deaden noise and vibrations to manageable levels.

It’s important to mention that such blenders are pretty expensive, and such is the case with the Vitamix Quiet One, which costs around $USD1100.

You can also make your own sound-dampening blender enclosure. Cut a hole in the bottom of a cardboard box just big enough for the blender’s power cord to fit through. Line the inside of the box with acoustic tiles or foam, and place the blender inside. The box will help muffle the sound of the blender as it operates.

If you only need to use a blender occasionally, or if you don’t want to invest in a new one, there are some ways you can reduce the noise it makes.

Fill the blender jar with ingredients before turning it on. This will help muffle the sound of the blades as they start to spin.

Add liquid to the ingredients in the blender jar. This will help create a smoother consistency and reduce the amount of noise the blades make as they chop up the ingredients.

Put a towel over the top of the blender jar while it is running. This will help further muffle the sound of the blender.

Conclusion

Above are some of my most recommended methods on how to silence a blender.

However, silencing a blender doesn’t mean you entirely get rid of the noise problem; instead, you’re reducing blender noise to manageable levels.

If you’re not on a budget, I would highly recommend you get a quiet blender.

It’ll not save you money, but it’ll save you time and all the hassles of trying to make your noisy one quieter.
