Ryobi's RY404100 Whisper Series, at a published 57 dB while moving 730 CFM. EGO's two flagship handhelds both publish 64 dB. Greenworks publishes no figure for its 730 CFM blower at all. Those three facts are the entire evidence base, and this page is what can honestly be built on them.

The published figures

BlowerPublished noisePeak CFMWeight
Ryobi RY404100 Whisper Series57 dB7309.4 lb
EGO LB650464 dB650Not published
EGO LB765064 dB7654.6 lb bare
Greenworks 80V axialNot published7305.5 lb bare
EGO LB6000 backpackNot published60012.5 lb

Each figure is the manufacturer's own, measured under its own conditions. There is no shared test standard across these brands, so the numbers are directional rather than laboratory-comparable.

What 7 decibels actually means

The arithmetic — The logarithmic scale
Decibels are logarithmic: +10 dB = 10x the sound intensity
7 dB difference = 10^(7/10) = about 5x the intensity
Human perception is roughly: +10 dB = "twice as loud"
So 7 dB reads as roughly half as loud, not 11% quieter

This is why the gap is worth caring about. If the two figures were measured the same way, the EGO is putting out about five times the sound intensity of the Ryobi while moving less air. The caveat matters — they were not measured the same way, because there is no shared standard here — but a five-to-one arithmetic gap does not vanish under measurement differences.

What Ryobi actually did

The 57 dB figure is not incidental. Ryobi describes noise-dampening foam and a uniquely positioned fan, branded as Whisper Series, with a claim of 86% quieter than gas. That is a named engineering program with budget behind it, and it shows in a quantifiable way: 730 CFM at 57 dB is more airflow than the 64 dB EGO LB6504 produces.

The cost shows up in the weight column. At 9.4 lb the Ryobi is the heaviest handheld here by a wide margin — twice the EGO LB7650's 4.6 lb bare figure, though the two brands may not be using the same weighing convention. Noise-dampening foam and a larger housing have mass. That is a real trade, and for a tool you hold at arm's length it is not a trivial one.

The blowers that publish nothing

Greenworks publishes no decibel figure for its 80V 730 CFM axial blower. EGO publishes none for the LB6000 backpack.

We are not going to spin that into an accusation. An absent number is an absent number, not evidence a tool is loud, and there are ordinary commercial reasons a spec sheet omits things. What it does mean is that nobody has committed to a figure you could hold them to — so if noise is your deciding factor, you are choosing between brands that made a claim and brands that did not.

The same pattern appears, much more starkly, in mowers: not one of the six flagship battery mowers we compared publishes a decibel figure at all. We wrote that up honestly rather than inventing a ranking — the quietest mower page is the result.

What the number does not capture

A single A-weighted decibel figure describes loudness, not character. Two tools at the same reading can be very differently annoying depending on the frequency they sit in — a high-pitched whine carries further and irritates more than broadband rush at the same level. None of these manufacturers publishes a frequency spectrum.

Nor do these figures tell you the measurement distance, which conventionally matters enormously. Neither Ryobi nor EGO states one on the product page.

So: use 57 versus 64 as directional evidence that one company engineered for this and one did not. Do not treat it as a laboratory result, because it is not presented as one.

If noise is genuinely your priority

  1. Buy the Ryobi. It is the only cordless blower here with both a low published figure and a named noise-engineering program behind it.
  2. Run it below turbo. Air speed drives noise steeply. Working at 160 MPH on the low-speed tip rather than 190 is the single biggest thing you control, on any blower.
  3. Accept the weight. 9.4 lb is the cost of the foam and the housing. If that is not acceptable, you are choosing a different priority and should say so to yourself honestly.
  4. Time of day beats decibels. No blower in this category is quiet at 7am. The 7 dB you can buy matters less than the two hours you can wait.

Our arithmetic — Published noise gap
7 dB quieter than EGO's 64 dB

Decibels are logarithmic: a 7 dB drop is roughly a 5x reduction in sound intensity, and is perceived as roughly half as loud. Both figures are manufacturer-published under their own test conditions, so treat the gap as directional, not lab-comparable.

What the numbers favor

  • 57 dB published -- the quietest figure any manufacturer on this page publishes
  • 730 CFM while doing it, second only to the 765 CFM EGO
  • Ships with two 4Ah packs (320Wh total) in the kit
  • Publishes high AND low runtimes rather than an average

What they don't

  • 9.4 lb is the heaviest published handheld weight here, roughly double the EGO LB7650 bare
  • Manufacturer noise figures are measured under each brand's own conditions -- not a like-for-like lab comparison
Skip this one if

you need to move soaked leaves off a large property fast. Quiet costs air speed, and 190 MPH is the lowest peak here.

Our arithmetic — Watt-hours per turbo minute
~18.7Wh/min

280Wh (56V x 5.0Ah) over the published 15-minute turbo runtime = about 18.7Wh per minute. On low, 280Wh over 150 minutes is about 1.9Wh/min -- turbo costs roughly 10x the energy per minute.

What the numbers favor

  • Highest published CFM and MPH of any handheld here
  • Publishes BOTH turbo and low runtimes, so the trade-off is visible instead of averaged away
  • 4.6 lb bare -- the lightest published weight of the handhelds on this page

What they don't

  • 15 minutes of turbo on a 5.0Ah pack is the real constraint, whatever the 90-minute average says
  • Sold bare in most configurations; budget for a battery and charger

Common questions

What is the quietest cordless leaf blower?
Ryobi's RY404100 Whisper Series, at a published 57 dB while moving 730 CFM. That is the lowest published figure of any cordless blower we compared, and Ryobi describes it as 86% quieter than gas.
How much quieter is 57 dB than 64 dB?
Decibels are logarithmic, so 7 dB is roughly a fivefold reduction in sound intensity and is perceived as roughly half as loud. Both figures are manufacturer-measured under their own conditions, so treat the gap as directional rather than precise.
Is a quiet leaf blower less powerful?
Not necessarily. The 57 dB Ryobi moves 730 CFM, more than EGO's 64 dB 650 CFM model. The cost of the noise engineering here shows up in weight -- 9.4 lb against 4.6 lb for the lightest handheld.
Which brands do not publish a noise figure?
Greenworks publishes no decibel rating for its 80V 730 CFM blower, and EGO publishes none for its LB6000 backpack. An absent figure is not evidence that a tool is loud, but it does mean nobody has committed to a number.
Are cordless blowers quiet enough for early morning use?
That depends on your local noise ordinance and your neighbors, not on a specification. What the figures show is a real spread within the cordless category itself -- so 'it is electric' is not by itself an answer to a noise complaint.
