Is the Ninja personal blender quiet?

Blenders are a staple kitchen appliance found in many homes. They allow you to quickly and easily blend smoothies, shakes, sauces, dips and more. However, traditional full-sized blenders can be loud and disruptive, especially if you’re making early morning smoothies while the rest of the house is still sleeping.

That’s where personal blenders like the popular Ninja personal blender can come in handy. Their small size and convenient single-serve blending cups make them an attractive option for kitchens where space is limited. But how quiet are they really when in use?

How Quiet Are Ninja Personal Blenders Compared to Other Models?

The Ninja personal blender is designed to be fairly quiet thanks to its 600-watt motor base and blade assembly inside the blending cup, which helps dampen noise. Most users report that it operates at around 60 to 70 decibels, compared to larger blenders which can reach 80 to 90+ decibels when blending.

Blender Noise Level (in decibels)
Ninja Personal Blender 60 – 70 dB
Average Full-Sized Blender 80 – 90+ dB

For comparison, normal conversation is about 60 dB, while a vacuum cleaner is around 70 dB. So the Ninja personal blender noise level is not insignificant, but it’s considered relatively quiet compared to other blenders.

Factors That Affect the Ninja Blender’s Noise Level

While the Ninja personal blender is one of the quieter models available, there are several factors that impact just how quiet or loud it is:

  • What you’re blending: Thicker, tougher ingredients like ice, frozen fruits, nuts, or fibrous greens require more blending power. This usually translates to a higher noise level.
  • Blender cup capacity: The larger 24 oz blending cup is slightly louder than the smaller 18 oz cup.
  • Speed setting: The highest “max” speed produces more noise than lower settings.
  • Motor wear: Older blenders with worn motors tend to vibrate and be louder during use.
  • Blade assembly: A loose blade that isn’t properly attached to the cup can generate more noise.
  • Surface under the blender: Placing the blender on countertops or tables that amplify vibrations can make it seem louder.

Tips for Keeping Your Ninja Blender Quiet

While the Ninja blender is designed to operate at a lower noise level, there are some things you can do to help dampen sounds even further:

  • Use a blender mat or place a damp kitchen towel under the blender base to absorb vibrations.
  • Avoid blending right up against walls, cabinets, or other solid surfaces that can amplify sound.
  • Blend for shorter durations by pulsing rather than running continuously.
  • Use lower speeds instead of max speed unless necessary.
  • Pause blending periodically to let the motor rest.
  • Make sure the blade assembly is securely tightened onto the cup.
  • Replace older, worn out blender parts like blades and cups.

Is the Ninja Blender Loud Enough to Wake Someone Up?

This depends on where you live and how heavy of a sleeper those around you are. In a quiet home with thin walls or doors, the Ninja blender set on max speed could potentially wake someone up in a nearby room.

However, using some noise dampening techniques like placing it on a mat or towel, blending in short pulses, and keeping speeds lower can help mitigate noise. Overall, the Ninja is significantly quieter than many standard blenders, making it a good option if you need to blend early in the morning but don’t want to disturb others.

How Loud is the Ninja Blender Compared to a Vitamix?

Vitamix blenders are popular high-powered models known for their durability and blending performance. However, they also tend to be significantly louder than the Ninja personal blender.

On average, Vitamix blenders operate around 90 to 95 decibels while in use. That’s about the noise level of a lawn mower engine. In comparison, the 60 to 70 dB noise range of the Ninja blender makes it 20 to 30 decibels quieter.

The main reasons Vitamix blenders are louder include their stronger motors, larger container sizes, and faster blade speeds needed to pulverize tough ingredients. So if keeping blender noise to a minimum is a priority, the Ninja is a better choice.

Is the Ninja Blender Too Loud for Apartments?

For most apartments and condos with average insulation between units, the Ninja personal blender should not be too loud provided you take some precautions.

Using it during daytime hours, keeping speeds lower, blending in short pulses, and placing it on a dampening mat to absorb vibrations can help keep noise levels down. It may still be audible through walls, but likely not excessive compared to other typical apartment noises.

If you have exceptionally thin walls or need to blend very early or late, it’s still best to be courteous and find out if neighbors can hear it. But in general the Ninja produces low enough noise levels to not be disruptive for multi-family living.

Is the Nutri Ninja or NutriBullet Quieter?

Nutri Ninja and NutriBullet are two other popular personal blender brands that compete with the Ninja blender line. In terms of noise levels, the Nutri Ninja and Ninja personal blender are nearly identical, both operating around 60 to 70 decibels.

The NutriBullet Pro is slightly louder according to some user reviews, likely reaching around 70 to 80 decibels. This may be due to its stronger 900 watt motor compared to the Ninja’s 600 watts.

So when it comes to the quietest option, the Nutri Ninja and Ninja personal blender are comparable, while the NutriBullet Pro may produce a bit more noticeable noise.


The Ninja personal blender is designed to blend quietly thanks to its 600-watt motor, small size, and noise-dampening cup design. While not completely silent, it operates at a lower 60 to 70 decibel level compared to larger, more powerful blenders.

Factors like ingredients, speed settings, motor wear, and placement on countertops can impact its noise. But using noise-reducing techniques and being considerate of others can minimize any disruption.

Overall, the Ninja offers quieter blending performance than many blenders, especially full-sized models like the Vitamix. This makes it a good option for early morning smoothies, apartments, and any setting where blender noise needs to be kept to a minimum.
