A blender is the loudest thing most kitchens own, and it runs at the hours when a house is quiet: before work, after the kids are asleep. You would think its makers would compete on the number. They do not. Of the home blender brands we read, not one publishes a decibel figure for a model sold in the US.
The figures that do exist come from the commercial side, and mostly from manuals written for Europe. We found twelve US-sold blenders with a maker figure, from three makers, and they come in three kinds that cannot be ranked against each other.
Our picks are listed above, with full specifications for each.
Three kinds of number, never mixed
Sound pressure at 1 m, measured. Santos, the French bar equipment maker, declares an A-weighted emission sound pressure level for the #62: 63 dB(A), with an uncertainty K of 2.5 dB, measured with the appliance loaded, the microphone 1 m away and 1.6 m off the floor, under NF EN 12852, ISO 11201 and ISO 4871. That is a measurement in the full sense: a value, a distance, a standard and an error bar. Santos does not say which speed or program it used, so we do not name one. The #62 is the only product in this group.
Equivalent continuous sound level, as a ceiling, at maximum speed on no-load. Every Hamilton Beach Commercial manual we read carries the same sentence with a different number: "The equivalent continuous sound level when equipment is operating at maximum speed on no-load is less than" some figure in dB(A). The condition is stated, top speed with an empty jar, but no distance and no standard. Five current models sit at less than 81 dB(A): the Eclipse, the Summit Edge, the Tempest, the Fury and the Expeditor 600. Five sit at less than 85: the Rio, the Tango, and the Expeditor 510, 900 and 1100. Within this group the ranking is fair, because the wording is identical. Across to the Santos figure it is not, because one is a measured level at a named distance with a load and the other is an upper limit with neither.
A bare "db" ceiling at 1 m. CRANDDI, an Amazon-first brand, says its K90's shield reduces "the noise to less 70db(within 1 meter)". It names a distance, which is more than Hamilton Beach does, but it is not marked A-weighted and names no speed or load. It stays in a group of its own.
So there is no single "quietest" here. There is a quietest measured value (Santos, alone in its group), a lowest ceiling among the Hamilton Beach Commercial maximum speed declarations (a five way tie at under 81 dB(A)), and one unweighted figure that we report and do not rank.
The Eclipse's number went up, and that is good news
Hamilton Beach Commercial's Eclipse, the HBH755, is the blender its catalog sells on quiet: "QuietBlend Technology - Reduces motor noise and works with the Quiet Shield enclosure to lower sound to a conversation level." Its 2016 and 2019 manuals declared "less than 70dB(A)" with the mixer "operating on no-load", no speed named.
The 2023 manual for the HBH755R and the 2025 manual for the HBH755 series changed the sentence. They now say "operating at maximum speed on no-load is less than 81 dB(A)". The number rose by 11 dB, and the condition gained the words that make it meaningful. A declaration without a speed lets the maker pick the gentlest one. A declaration at top speed is the one you can plan around. We use the current wording, show the old one in the catalog facts, and would rather rank a maker for the honest sentence than punish it.
The same rewrite put the shielded Eclipse and Summit Edge on exactly the same ceiling as the unshielded Tempest, Fury and Expeditor 600. That is not a sign the Quiet Shield does nothing. It is a sign that an empty jar is not a smoothie.
What no-load leaves out
A blender makes noise from three places: the motor and its cooling fan, the blade and coupling, and whatever is in the jar hitting the jar wall. Ice is the loud part. A no-load figure measures the first two and skips the third entirely.
That is why Santos's figure is the most useful in this guide even though it is not the lowest looking. The #62 is measured with the appliance loaded, so the hood, the brushless motor and the anti-vibration jar mat all get to show what they do against real contents. Hamilton Beach Commercial's ceilings are good for comparing its motors against each other and poor for predicting a frozen margarita.
For a sense of scale: roughly every 10 dB is a doubling of perceived loudness, so a blender at 80 sounds about twice as loud as one at 70 in the same room, and the gap between two Hamilton Beach ceilings, 81 and 85, is audible. For more on reading these numbers, see sound power versus sound pressure.
Why the numbers come from commercial manuals
Commercial blenders sold in Europe are machinery, and the EU machinery rules require the maker to declare the A-weighted emission sound pressure level at the workstation, or say that it does not exceed 70 dB(A). That requirement is why Santos prints a full declaration and why Hamilton Beach Commercial prints its sentence in every international manual, in a dozen languages, on its own use and care server. The US versions of these blenders are the same series at 120 V, listed side by side with the 230 V versions in Hamilton Beach Commercial's 2023 catalog, which is the mapping we rely on. The figures describe the series as the maker documents it; we found no separate figure for the 120 V units.
Home blenders have no equivalent rule and no EU energy label, so there is nothing forcing a number onto the page. The one home exception we found, Philips, prints "Noise level: Lc = 89 dB [A]" in the manual for its Avance HR3868 high speed blender. Philips does not say whether that is sound power or sound pressure, and its US page now marks the HR3868/90 discontinued, so it is not in our table.
The silent aisle
Vitamix publishes no figure for any blender we checked. The Quiet One's commercial page promises "Patented Noise Reduction" and "reduced noise"; its sell sheet and owner's manual contain no decibel value, and neither do the international and EMEA Ascent manuals we read. Blendtec's Stealth 885 spec sheet calls it "the world's quietest commercial blender" and says its enclosure lets it operate "at the sound level of normal conversation", without a number, and the Stealth owner's manual says the enclosure gives "the quietest blending experience available", again without one. Breville's manual for The Q prints no figure. Hamilton Beach's home Sound Shield 950 and Professional Quiet Shield product pages say the blenders are quieter, and the Sound Shield 950 manual we read gives no figure. Braun's TriForce manual, Smeg's BLF03 manual and product pages, Zwilling's Enfinigy manuals, and Kuvings's US blender pages publish no figures either. We could not read KitchenAid's current Power Plus blender manual; the maker's server refused the request. Ceado's B285 silent blender manual has no figure, and Waring's spec sheet server had an expired certificate, so we could not read it. We did not find maker documents with figures for Ninja, Nutribullet, Oster or Cuisinart, and we did not include any brand we could not check.
These blenders may well be quiet. Their makers do not say how quiet in any document we could read, and a guide that ranks published figures cannot rank them.
How to use this guide
If you run a bar or a cafe and noise is part of the customer experience, start with the Santos #62, because it is the only figure measured the way you will hear it, loaded and at a metre. If you are choosing between Hamilton Beach Commercial models, the under 81 and under 85 ceilings are a fair comparison of their motors, and the Quiet Shield on the Eclipse and Summit Edge is there for the ice those ceilings leave out.
If you want a quiet blender at home, the honest answer is that no mainstream home brand gives you a number to shop on. An enclosure is the one design feature that reliably helps with ice, and the CRANDDI K90 is the only enclosed blender we found at a home price whose maker prints any figure at all, even if that figure is too loosely stated to rank.
We did not measure any of these blenders. Every figure is the maker's own, quoted as published, with the condition, distance and standard attached wherever the maker attached them, and the document it came from named in the catalog facts.
