Outdoor
Buying guides for outdoor, ranked by the noise figures makers publish.
Quietest drone: DJI's Air 3S and Air 3 print the lowest sound power, 81 dB
DJI prints a sound power level for four current US drones in their EU class tables: 81 dB for the Air 3S and Air 3, 82 for the Mavic 3 Pro and 83 for the Mavic 3 Classic. Sub-249 g C0 models such as the Mini 4 Pro and Neo print none, and the 81 dB Avata 2 is marked discontinued.
Quietest outboard motor: Tohatsu's MFS6D lists 79.0 dB(A) for the operator
Tohatsu is the one outboard maker whose US manuals print a noise value: 79.0 dB(A) operator sound pressure under ICOMIA 39/94 Rev.1 for the 4 and 6 hp MFS4D and MFS6D, 79.1 for the MFS2.5C and up to 90.4 for its 75 to 150 hp engines. Honda, Mercury and the electric makers give claims, not values.
Quietest pond pump: EasyPro's KLC25 prints 35 dB, Hiblow's WG-2 40 dBA at 1 m
No maker we checked prints a single noise figure for a submersible pond water pump. Air pumps do: EasyPro lists 35 dB for its KLC25 and KLC40, Hiblow 40 dBA at 1 m for the WG-2, and Pondmaster 40 dBA for the AP-40. Each maker states its figures its own way, so we rank within each one.
Quietest leaf vacuum: ECHO's ES-250 has the lowest 50 ft rating, 70 dB(A)
ECHO's ES-250 Shred 'N' Vac rates 70 dB(A) at 50 ft under ANSI B175.2 and Husqvarna's 125BVx 72.3, the only two leaf vacuums rated on that test. Troy-Bilt's TB272V lists 74 with no basis, and Sun Joe gives three corded models 96 dB of sound power. No maker prints a vacuum-mode figure.
Briggs & Stratton generator decibels chart, 58 to 70 dB at 7 m across 20 models
The P2400 inverter is the quietest Briggs & Stratton, 58dB at quarter load on its UK page. Among home standby units, each PowerProtect+ sheet gives 62 dB(A) for Low Idle Mode, with 66 or 67 for normal operation, all at 7 m. Twenty current US models, from Briggs pages and spec sheets read October 24, 2026.
ECHO leaf blower decibels, 64 to 80 dB(A) at 50 ft across 12 gas blowers
ECHO's low-noise PB-255LN handheld lists 64 dB(A) at 50 ft by ANSI B175.2, and the PB-265LN and PB-760LN backpacks 65. Its other gas blowers run from 70 to 80. ECHO prints no decibel figure for any of its eight 56V battery blowers, so none of them can be placed on the scale.
Predator generator decibels, 56 to 78.5 dBA on Harbor Freight's own figures
Harbor Freight gives the Predator 3500 Super Quiet inverter a 56 dBA Sound Rating, its lowest, though a 2025 manual prints 57 dB(A) at 23 feet and 25% load. The 2000 and 2500 list 58; the open frame 4550 lists 64.6, and conventional Predators run 70.9 to 78.5 dBA.
Quietest 12V fridge: the Dometic CFX3 100 at 36.5 dB(A), and five more with real figures
Dometic's US manual gives the CFX3 100 a noise emission of 36.5 dB(A), against 44 for the CFX3 35 and 46 for the CFX3 25. Whynter lists 39 dBA for its FMC-350XP and 40 for the FM-45G. Neither maker names a distance, so each brand is ranked on its own.
Quietest RV generator: built-in Onan sets at 10 ft and RV-ready portables
Cummins rates its Onan QG 2800i at 65 dBA from 10 ft at half load, the lowest of 15 current built-in RV sets. Among 30 amp portables, Honda's EU2200i Companion lists 48 dB(A) at quarter load from 23 ft. The two kinds use different tests, so each is ranked only against its own kind.
RYOBI blower decibels chart, 55 to 65 dB across twelve models
RYOBI prints a decibel row for twelve current US leaf blowers, from 55 dB on the 600 CFM blower in the RY40960 combo to 65 dB on the 18V P21011, with no distance or standard named. Its mowers, trimmers and snow blowers offer only percent-quieter-than-gas claims.
Greenworks outdoor tool decibels chart, 54 to 95.4 dB across seven tool types
Greenworks rates its AiMowbot robot mowers at 54 dB, the 48V BL2002B00 backpack blower at 65 dB and three 3000 PSI washers at 68 dB, with no distance or standard. Only the Pro 80V 21 inch mower gives distances: 84.9 dB at the user, 95.4 dB at 15 ft and 61.83 dB at 50 ft.
Kohler generator decibels chart, 52 to 66 dB(A) in exercise across ten models
Kohler's 24RCLA, 30RCLA and 38RCLC list 52 dB(A) in engine exercise and 60 dB(A) in normal operation at 23 ft (7 m), the quietest of 8 points, at no load. The quietest air-cooled Kohler, the 26RCA, lists 56 and 67. Ten current US models, from spec sheets read October 23, 2026.
DEWALT outdoor tool decibels chart, 58 to 96 dB across blowers and pruners
DEWALT rates seven US blowers from 58 to 96 dB and two pruners at 75 dB, but its Noise Rating row names no distance or standard; footnotes on the DCBL724 and DCBL777 pages describe a bystander 50 feet away. The mowers, string trimmers, chainsaws and hedge trimmers carry no US figure at all.
Makita outdoor tool decibels, 79.4 to 95 dB(A) at the ear across four tool types
Makita's European manuals put the GBU01Z blower lowest at the operator's ear, 79.4 dB(A) with its end nozzle and a guaranteed 91. The XML07Z, XML08Z and XML09Z mowers declare 81, the XHU09Z hedge trimmer 82 and the XCU11Z chainsaw 89. Makita's US site prints only a 60 or 61 dB(A) ANSI rating for blowers.
Quietest riding mower: the four EGO riders that declare a figure at the ear
EGO's 52 in. Z6 zero-turn declares 82.5 dB(A) at the operator's ear, and its T6 tractor and two 42 in. Z6 models declare 83.9 to 84.3, all with a K of 3. No gas riding mower we checked publishes a figure. Every number comes from an EGO manual.
Quietest pool pump: the variable-speed figures that name a speed or a distance
Pentair is the one pool pump maker we read that says how far and how fast: 45 dB at 10 feet for the IntelliFlo3 VSF running at 40 to 50%. Madimack prints lower numbers, 32.9 at 30% speed for the InverFLOW Plus 1HP, with no distance or unit. Hayward and Waterway print none.
Anker SOLIX noise figures explained, from 0 to 20 dB under 200W
The C1000 Gen 2 has Anker SOLIX's smallest number, 0 to 20 dB, but only while discharging 200W or less. Just four current US models print a figure, each at its own condition: the S2000 at 30 dB under 600W, the C2000 Gen 2 at 30 dB under 1,000W and the C300 at 25 dB from 3.3 ft, the only one with a distance.
BLUETTI noise level starts at 16 dB, in Elite 200 V2 Silent mode
The Elite 200 V2 is BLUETTI's best-documented quiet station: 16 to 30 dB in Silent charging, which its manual caps at 800W input, and below 50 dB during full operation. No BLUETTI figure gives a distance, and spec-table maximums run from 45 dB on the 200W Elite 10 Mini to 50 dB on four bigger units.
DuroMax generator noise level, from 52 dB at 25% load
The XP2300iH is the quietest DuroMax: its manual lists 52 dB at 25% load, 9 dB under the next DuroMax inverter on that basis. DuroMax rates its inverters at 25% load and its biggest HX open frame models at 50%, gives a tri fuel model the same figure as its dual fuel twin, and states no distance anywhere.
Are Pulsar generators loud? From 56 dB at 7 m and quarter load
The 1,200 running watt PGD16iSCO is the quietest Pulsar with a load and a distance stated: 56 dB at 7 m and 1/4 load, in its owner's manual. Pulsar's spec tables give only a bare Volume (dB); the 7 m figures, at quarter or half load, are in some manuals, and on several models the page and manual disagree.
EcoFlow noise level: 25 dB or less at 600W on the DELTA 3 Max
The DELTA 3 Max, DELTA 3 Ultra and DELTA 3 Ultra Plus share EcoFlow's lowest figure with a distance: 25 dB or less at 600W, taken 1 m away at 25°C room temperature while charging or discharging. Only the DELTA 3 and DELTA 3 Plus add a louder step, under 40 dB at 1200W, and no figure covers X-Stream fast charging.
Firman generator dB levels, stated at 1/4, 1/2 or 3/4 load
Nine Firman Whisper inverters share its lowest figure, 58 dB at 1/4 load, and the dual fuel WH03342 is the lowest priced of them with CO Alert. Firman quotes other models at 50% or 3/4 load, adds 7 m only on its gasoline open frame line, and on five pages gives two different numbers.
How loud is a Jackery? Quiet Mode 30 dB, full load 45 to 51.7 dB
The Explorer 2000 v2 is the quietest Jackery with figures at both ends: 30 dB in Quiet Mode, 45 dB at full load, both at 1 meter. Five more current models share the 30 dB Quiet Mode figure, and at full load the HomePower 3600 Plus and Explorer 5000 Plus list 50.3 and 51.7 dB. Fast charging has no figure.
Milwaukee blower decibels, M18 FUEL vs MX FUEL: 54 to 64 at 50 ft
The M18 FUEL 3017-20 is the quietest Milwaukee blower, rated by ANSI B175.2 at 54 dB(A) from 50 ft, five decibels under the QUIK-LOK attachment with the same 500 CFM. The MX FUEL MXF600 backpack moves 800 CFM at 64 dB(A), and Milwaukee prints no comparable figure for its US trimmers, saws, hedge trimmers or mower.
The quietest dual fuel generators
Dual fuel and tri fuel generators run on gasoline, propane or natural gas, and lose running watts on the gaseous fuels. We group every maker figure by its stated load and distance, list each maker's propane derating, and pick the quietest in each group.
The quietest lightweight generators you can carry
If you have to lift it into a car, carry it to a site or set it down on a tailgate, weight comes first. We list each maker's stated weight, group the noise figures by the distance and load each maker gives, and cover run time at quarter load, CO shutoff, eco mode and two light units in parallel.
The quietest snow blowers, by the makers' own figures
Only two snow blower makers print real noise figures for their US models: Husqvarna, and EGO by way of its European manuals. The quietest by operator figure and by guaranteed sound power, single-stage against two-stage, battery runtime, and what local rules say about clearing before dawn.
The quietest cordless string trimmers for early and late edging
Edging before work or after dinner, the neighbors hear the whole trimmer, which the guaranteed sound power describes. Battery string trimmers ranked on that figure, and separately on the ear figure within each test standard, with the low settings, heads, line, runtime and weight that shape a quiet session.
The quietest electric chainsaws for storm cleanup and firewood near neighbors
Battery and corded chainsaws ranked on maker declarations for a yard with houses close by: the figure at your ear, the guaranteed sound power the street hears, what happens between cuts, chain speed and bar length, and the hearing protection the makers require.
The quietest electric pressure washers for close neighbors
Four Karcher models print 75 dB(A) sound pressure at the operator, the quietest electric pressure washer figures with a stated basis. Washing a car, deck or patio with a neighbor a few yards away: why Karcher and Sun Joe cannot be ranked together, and what Total Stop and a 35 ft cord change.
The quietest inverter generators under $1,000
Inverter generators at a maker list price of $1,000 or less, sorted by what each maker's noise figure states: load and distance, load only, distance only, or neither. Watts for the money, eco mode, parallel kits, CO shutoff, and where Honda and Yamaha sit.
Which STIHL leaf blower is quietest? BGA 30, 50 dB(A) at 50 ft
At 50 dB(A) from 50 ft under ANSI/OPEI B175.2, the BGA 30 is the quietest STIHL blower, and the BGA 50 the quietest on 36 V at 55. STIHL USA prints that 50 ft row only for blowers; for saws, trimmers, hedge trimmers and mowers, the operator figures come from STIHL's UK and Australian data and its international manuals.
WEN generator decibels: what "quarter load, 22 feet" means
The 56125i is WEN's quietest generator with both conditions stated: "51 decibels (at quarter load from 22 feet away)", for 1,000 running watts. Nearly every WEN inverter figure is a quarter-load one, eight pages add 22 feet, and WEN publishes no full-load figure for any current inverter.
Yamaha generator decibels come as a range: 1/4 load to rated load
The EF3000iS is the quietest Yamaha at light load: 54.5 dB(A) at 7 m at the 1/4 load end and 61.0 at rated load, per its US manual, with the economy control switch on. Yamaha prints each figure under a 1/4 load to rated load heading, and its EF4500iSE spec page, features page and manual give three different ranges.
How loud is a Champion generator? 53 to 79 dBA from 23 feet
Champion's enclosed inverters of 2,000 to 2,500 watts are its quietest portables, all listed at 53 dB(A); the 2500W Inverter 201317 says "53 dBA from 23 feet". Champion names that distance on most pages but never a load, and on four pages its text and spec table give different numbers.
EGO mower and leaf blower decibels, declared at the ear in Europe
With its line head, the ST1511T string trimmer is the quietest EGO tool at the operator's ear that maps to a US model: 78.1 dB(A) in the EU manual for the ST1510E-T. The LB5804 blower declares 78.4 and the LM2020SP mower 79.2. EGO's US pages print only bare 62 to 64 dB figures for consumer blowers.
Generac generator noise level in weekly exercise and in an outage
The 10 kW model 7257 is the quietest Generac: 49 dB(A) in Quiet-Test low-speed exercise and 61 dB(A) at normal load, both at 23 ft (7 m) from the front. Every air-cooled standby sheet gives those two rows; the liquid-cooled Protector sheets report the quietest of 8 points, and the portables give no figure.
Honda generator decibel chart: 42 to 73 dB(A) at 7 meters
The EU1000i is the quietest Honda generator: 42 dB(A) at 1/4 load and 50 dB(A) at rated load, as sound pressure 7 meters from the control panel side. Honda quotes its other inverters at the same two loads and its six EM, EB and EG models at 50% and rated load, so only rated load lines up across all 13.
Husqvarna leaf blower decibel chart, from 60 dB(A) at 50 ft
The 530iB is the quietest Husqvarna blower to the neighbors: its US manual rates it at 60 dB(A) from 50 ft by ANSI B175.2, and its US page 76.9 dB(A) for the operator, 92 guaranteed. Almost every Husqvarna US page has a Sound and noise table, and where page and manual disagree, by up to 13 decibels, both are quoted.
The quietest backpack leaf blowers, for big yards and blower rules
Backpack blowers ranked on the figure a leaf blower rule is written in: dB(A) at 50 feet under ANSI B175.2. Plus what the makers declare at your ear, the run time they publish, and the hearing protection their manuals require.
The quietest battery lawn mowers for early mornings and small yards
For mowing with neighbors close by and still asleep, watch the guaranteed sound power rather than the figure at your ear. Battery walk-behind mowers ranked on both, kept apart, with the ECO and quiet modes makers offer and the runtime and deck size that come with them.
The quietest portable generators for home backup
A 5,000 to 12,000 watt portable generator sits 20 feet from your house, often near a window or a neighbor's wall, for days. We group every maker's figure by its stated load and distance, from Honda's 52 dB(A) at quarter load and 7 meters to claims with no condition at all.
The quietest home standby generators, by exercise and running noise
Home standby generator makers publish two figures at 7 meters: a quiet weekly exercise and a louder running level. Exercise and running numbers are ranked separately here, for Generac, Kohler, Briggs & Stratton, Cummins and Champion, and show what a neighbor and a noise ordinance will care about.
Quietest Westinghouse generator: why 19 iGen models tie at 52 dBA
Nineteen iGen inverters share Westinghouse's lowest figure, 52 dBA, from the 1,000 running watt iGen1500c to the 3,900 running watt iGen5000, with no load or distance given. Only two pages name a load: at 25 ft and 25 percent load the iGen2800DFc lists 62 dBA, ten more than its own "as quiet as 52 dBA".
The quietest lawn edgers
Twelve US lawn edgers and edger attachments carry maker noise figures, from 73.8 dB(A) at the ear for a Makita battery combo to 94 for Husqvarna gas edgers. See the lowest guaranteed sound power, how STIHL declares its KombiSystem edgers, and which brands print nothing.
The quietest pole saws
The quietest pole saw with an ISO 22868 declaration is a STIHL battery model at 77 dB(A) at the ear. Sixteen pole saws with maker declared noise, ranked only within each test method, and the overseas manuals those figures come from.
The quietest tillers and cultivators
On a battery powerhead, one STIHL cultivator attachment is declared at 74 dB(A) for the ear; on a gas engine, 99. Ten tillers and cultivators with maker noise declarations, the quiet picks in each group, and the brands with no figure to their name.
The quietest pool heat pumps
Four pool heat pump makers print a noise figure, and only two state a clear distance. See the lowest declared numbers, 30.8 dB(A) at 10 feet for a Madimack and 32 dB(A) at 33 feet for an Aquastrong, and why Hayward, Pentair and Jandy publish none.
The quietest chainsaws
Battery chainsaws run from 83 dB(A) at the ear for a small STIHL to 96, against 99 for gas. Fifteen saws with maker declared figures, the Power Axe saws you can buy online, and the noise figures STIHL leaves out of its North American manuals.
The quietest hedge trimmers
Battery hedge trimmers declare 76 dB(A) at the ear for a full size STIHL up to 86.47 for an EGO, against 97 for gas. Twelve trimmers with maker figures, and why the smaller trimmers are not the quieter ones.
The quietest lawn mowers
Battery mower noise figures exist, just rarely on a US page: seven of the eight battery walk-behinds here declare 79 to 84 dB(A) at the operator, each on a STIHL UK page or in a European manual. The quietest EGO and STIHL mowers, and why gas is closer than you think.
The quietest string trimmers
Nine battery string trimmers have maker noise figures we can tie to their US model, starting at 74 dB(A) at the ear, against a 105 dB(A) gas contrast. Which makers declare under real standards, and which publish nothing for their US models.
The quietest leaf blowers, ranked on the 50 ft rating
STIHL's BGA 30 is the quietest leaf blower here, 50 dB(A) at 50 ft under ANSI B175.2, and the Milwaukee 3017-20 the quietest full-size one at 54 dB(A). Makers publish three kinds of noise figure; we rank on the one your neighbors hear, and read what handheld makers say about boost, run time on low and your own ears.
The quietest portable power stations
Power stations are silent until their fans spin up. Which makers put a decibel figure on that moment, what each figure was measured at, and which charging settings keep one hushed through the night.
The quietest pressure washers
Pressure washer noise figures barely exist: three brands print one, and they print different quantities. What they say, and why no gas model can be compared at all.
The quietest robot lawn mowers
Robot mower makers print 55 to 65 dB, and only one brand says what it measured. Why a 57 can be quieter than a 55, and which claims deserve trust.
The quietest generators for camping and RVs
Generator makers quote noise at different loads and distances, so the numbers rarely compare. See who states what, the 60-decibel park rule, and what to buy.
