Vitamix, Blendtec, OmniBlend: Noise Comparison

0 Flares Facebook 0 Google+ 0 Twitter 0 Pin It Share 0 0 Flares ×

This model comparison video tests the relative noise levels during operation of several popular high-performance blenders. Featured are the OmniBlend V, the Blendtec Total Blender, the Vitamix Professional Series 750, and the Vitamix 5200. The Pro 750 is representative of all of the Vitamix “Next Generation” models, and the 5200 is comparable to all “traditional” models in the Vitamix home line of blenders.

A test is run using identical ingredients in each blender. The viewer can gauge the relative differences in noise levels simply by listening. As well, a sound meter is used on each blender.

This video has not been edited.

Per the sound meter, the Blendtec Total Blender registered the highest decibel output, followed by, in order, the Vitamix 5200, the OmniBlend V, and the Vitamix Professional Series 750. Though the differences in sound output are audibly apparent with the Blendtec Total Blender being the loudest model of those tested, the differences in noise levels between it and other models is not as drastic as numerous claims infer.

  1. For those who can’t or don’t want to watch the video, the Omni registered at 88.2, the Blendtec was 94.4 decibels,the Vitamix Pro 750 was 87.5 decibels, the Vitamix 5200 was 90.1 decibels

  2. Do you recommend hearing protection, if so, what type?

      Peggy, I am a strong advocate of hearing protection when using these blenders. I have a pair of protectors similar to what you see those who work on airport tarmacs wear. Most of these can be found for under $20.00. Sears or a retailer like them is a good place to look. I must admit, though, that I do not wear them all the time, or even regularly. This is a habit I would like to break.

  3. Do you know the decibels of the Nutri Ninja IQ? I was thinking of upgrading but I’m curious about the sound comparison and if would be louder?

  4. Had a Blendtec Total Blender but i found it very difficult to finish a whole juice cycle as I find it extremely loud. Literally made me weak in the knees (and not in a good way haha) and I was frightened that the blender might break down (I’m sure it won’t). I’m now looking to purchase my first Vitamix Total Nutrition Centre.

      Joseph, yes, as you discovered, high-performance blenders are loud. There is not a lot that can be done about it at this time. I wear hearing protection when I have it nearby. This is not always a convenient option, though.

      In general you will find the Vitamix to be slightly quieter than the Blendtec, but don’t expect it to be quiet. It still generates a fair bit of noise, itself. Best of luck!

  5. And I found the answer to my question posted on the comparison video of just the G-series and the C-series. These videos are great and each new video I watch is reassuring me that I made the right decision on which blender I ordered. We are expecting the Professional Series 750 any day now! I’m super excited 😀

      As you should be, Christine. It is a phenomenal machine. Happy blending!

  6. Hi, I am comparing 5300 vs. 7500 and I am wondering, which one is TRULY quieter? Since they are almost the same motor wise, are they the same loudness or is the 7500 indeed a quieter machine because it is “g-series”? I am concerned about how loud they are and if there is truly really any difference in loudness between the two machines ….. vitamix won’t answer this question for me for some reason …. thanks!

      Squirrel, I have not performed a direct noise comparison of these two models against one another so I cannot say for certain which one is louder. However, based on my tests of very similar models I would estimate the 7500 to be quieter, albeit slightly. The airflow design of the G-Series models is different than that of the C-Series, of which the 5300 is one. All my tests conclude the G-Series to be the quieter machines. Despite the common belief that the difference is significant, though, my real-world tests generally conclude that the noise level difference is often quite negligible.

  7. I have had 2 nutribullets and one generic smoothie maker. All are now broke. We are considering buying a vitamix because we heard it is top of the line. We only really make smoothies. What blender would you recommend?

    • Blenderdude

      Pattie, for smoothies you can be confident in literally any of the models you see in these videos. What you would need to decide on – along with price – are the “bells and whistles” that go into how these smoothies are made. For example, pre-programmed settings, preferred container size and shape, etc. To narrow down your choices you are going to have to create a checklist of features that are important to you. Please contact me directly with any and all of your specific questions. I will be happy to work with you throughout the selection process.

  8. Hi, I like your forum! The only thing I would add is that, for these really loud blenders, you might consider getting a sound enclosure. Now, I’m not talking about those flimsy ones that only amplify the sound. I’m talking about a sturdy one with door and a sound-absorbent pad. I’ve tried several, and the best one I’ve found by far is the Whisper Blend Sound Enclosure. You can’t go wrong. http://www.whisperblend.com.

    • Blenderdude

      Mary, those are indeed nice sound enclosures. I would recommend consulting with the manufacturer of your particluar blender to inquire as to whether using one might have ramifications on your warranty due to potential ventilation concerns.

  9. Just out of curiosity… with so many good blenders, how do you decide which one you use in your daily use? Which one do you find yourself using the most?

    Outside of doing the demonstrations, of course. 😉

    Great web site, by the way.

    • Blenderdude

      Lloyd, thanks for the compliment on the site. 99% of the time there is no decision to be made. I simply use the one that is on my countertop at the time. If and when I switch to another – for any reason – it will then remain on the countertop and receive all the use. I don’t switch them around randomly. There is usually a specific reason why I will pull one or another out. But how long it then stays on my counter is completely arbitrary.

  10. i am trying to decide which vitamix i will buy, and your noise factor, counter height, and blending small amounts info/videos were all educational. thank you so very much for taking the time to publish this.

    when i spoke with my industrial designer husband, he reminded me that the decibel system is exponential. i wiki’d it, and yes, it is logarithmic. in other words, multiply everything by 10.
    you show a 10 decibel difference in measurement for these blenders. this would be the equivalent to 10 x 10 difference in intensity, or a 100 fold difference.
    at first i thought with only a 10 db difference, i could see why claims of a 40% reduction would not be right. with the logarithmic difference, i can now see why this claim could be supported.

    of course, each person would have to decide for themselves what they wish to put up with. the Vitamix Advance Blender-Model# VM0115E w/ sound enclosure makes some sense to me, if i didnt want to wear ear muffs.

    90-95db is considered a level where sustained exposure can cause some hearing loss. fortunately, the vitamix finishes the job in very short time periods.

      Cynthia, you are correct about decibel calculations being logarithmic rather than linear. Just as importantly, for practical purposes proper measurement when comparing these levels should be taken from a common point of hearing, not from the point where sound originates. The video has been re-made and the current one takes all these considerations into account. I appreciate your input.

    • Cynthia, you are indeed correct about it being logarithmic, but this means that for a one-bel difference, the factor is 10 times. This means that for a 10-decibel difference, the factor is 10 times, since one bel is 10 decibels. For example, 90 dB is 10 times louder than 80 dB. For 100 times louder than 80 dB, you would need 100 dB. It’s the same thing with earthquakes on the Richter scale when you think of bels, and then to get decibels, you just multiply by 10.

      Blender Dude, I think your website is great! I love how you’re passionate and knowledgeable about what you do.

  11. Nice. The only competitor missing is the Blendtec DS… supposedly it is quieter than the Total Blender Classic. That said, I am surprised that the Blendtec was only slightly louder than the VM 5200.

    • Blenderdude

      Joe, from what I could tell when listening to it, the Designer Series is quieter than the Total Blender to about the same extent as the two Vitamix models you see in this video. In other words, you can tell a difference, but it is not drastic.
