If you’re on a budget and can’t get your hands on a quiet blender (check out my guide on quietest blenders on the market.), learning how to silence a blender could be your only getaway option.
You won’t spend a dime on some of the methods I’ve highlighted below, but you may need a few cheap soundproofing materials to effectively deaden blender noise.
It’s worth mentioning that making a blender quiet is just one of the different soundproofing projects to create a quiet and peaceful kitchen.
Below are some of the best ways on how to silence a blender.
Why Are Blenders So Loud?
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.
A-List of Ways on How to Silence a Blender
Is there anything you can do about blender noise? Yes, and below are some of the ways you can reduce blender noise.
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
If you frequently enjoy making frappes, smoothies, and juices, you’ll love 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.
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.
5. Change Blending Schedule
This may sound impossible, but it’s actually achievable, but I don’t often advocate it.
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.
6. 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.
7. Buy a Quiet Blender
The only sure way to get rid of blender noise would be to purchase a quiet blender.
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.
On how to Silence a Blender
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.
