People search for Husqvarna decibels because they are about to buy a blower, a mower or a saw and want to know what the neighbors will hear. Husqvarna answers more of that question than most outdoor brands. Nearly every product page on husqvarna.com/us has a "Sound and noise" table, and several battery blower manuals add the 50 foot rating that city leaf blower rules are written around. This page gathers every current US Husqvarna blower, walk-behind mower, Automower, string trimmer, hedge trimmer and chainsaw with a published figure, says exactly what each number is, and ranks like with like.
Every figure here is Husqvarna's own, read on October 4, 2026 from more than 100 US product pages and 35 US operator's manuals. How Husqvarna compares with other brands is a separate question. Our guide to the quietest leaf blowers ranks every brand on the 50 foot figure, and its sibling guides do the same for each tool type.
Our picks are listed above, with full specifications for each.
The three numbers Husqvarna prints
Husqvarna's US pages use three rows. "Sound pressure level at operators ear" is the noise at the user's head. The manuals say it is measured to ISO 22868 or EN ISO 11203 for most handheld tools, with a typical statistical dispersion of 1 to 3 dB(A). "Sound power level, measured" is the total noise the tool emits in a test, and "Sound power level, guaranteed (LWA)" is the ceiling under EU directive 2000/14/EC, which "also includes dispersion in the measurement result and the variations between different machines of the same model", in the manuals' words. Some blower pages add a guaranteed figure in boost mode.
The third kind of number lives only in some manuals: the bystander figure at 50 feet, measured to ANSI B175.2. That is the one ordinances use, often with a 65 dB(A) limit. Husqvarna's newer battery manuals print it under the odd label "Sound power level, measured at 50 ft. (15 m) per ANSI-B175.2", but a figure taken at a stated distance is a sound pressure reading, so we treat it as the 50 foot rating. Our sound power vs sound pressure explainer covers why the kinds of figure cannot be set against each other. This page never does: ear figures are ranked against ear figures, guaranteed against guaranteed, and 50 foot against 50 foot, within each tool type.
By the 50 foot ANSI B175.2 rating in Husqvarna's US manuals, quietest first:
- 530iB, handheld battery: 60 dB(A)
- 340iBT, battery backpack: 61 dB(A)
- 550iBTX, battery backpack: 61 dB(A)
- 570iBT, battery backpack: 64 dB(A)
- 525iB Mark II, handheld battery: 64.4 dB(A) in normal mode, 66 in Boost
- 125B, handheld gas: 72 dB(A)
- 125BVX, handheld gas with vacuum kit: 72.3 dB(A)
The 125B figures come from the manual dated June 2026 that Husqvarna links from both pages now. An earlier edition, which our leaf blower guide cites, read 71 for both. The 230iB and 350iB battery manuals, and the manuals for the gas 150BT, 350BT, 360BT, 525BX, 560BTS, 570BTS, 570BFS, 580BTS, 580BFS, 590BTS and 590BFS, print no 50 foot figure.
At the operator's ear, from Husqvarna's US pages, quietest first: 550iBTX 73 dB(A); 530iB 76.9; 230iB and 340iBT 79; 350iB 79.4; 570iBT 83.7; 525iB Mark II 85; 525BX 91; 125B, 125BVX and 350BT 94; 360BT 95; 560BTS 97; 570BTS and 570BFS 103; 580BTS and 580BFS 106; 150BT 110. The 590BTS and 590BFS pages print nothing.
By guaranteed sound power on the same pages: 530iB 92 dB(A); 550iBTX 94; 570iBT 96; 340iBT 97; 350iB and 525iB Mark II 101; 230iB 102; 350BT 104; 525BX 106; 570BTS and 570BFS 110; 360BT and 560BTS 111; 125B and 125BVX 112; 150BT 113; 580BTS and 580BFS 115. In boost mode the pages list 108 for the 230iB and 110 for the 350iB, a jump of six and nine decibels, and 96 for the 550iBTX.
Two blowers deserve a flag. The 550iBTX page says 73 dB(A) at the ear and a guaranteed 94; its own manual says 86 and 96. And the 125B page says 94 at the ear, 109 measured and 112 guaranteed, while the June 2026 manual says 92.6, 106.9 and 111. Our backpack blower guide sets the backpacks here beside other brands' on the 50 foot figure, and our handheld blower guide does the same for the 530iB and 525iB Mark II.
Only two. The W520i lists 84 dB(A) at the operator's ear, a measured 97 and a guaranteed 97 dB(A). The Lawn Xpert LE-322R lists a guaranteed 98 dB(A), no operator figure, and a "Sound power level, measured" of 66 dB(A) that cannot sit 32 decibels under its own guaranteed ceiling, so we ignore it. The gas W520 page prints nothing, and its manual says only to "Use hearing protection if the noise level is higher than 85 dB". Husqvarna's mower pages also claim "our electric lawn mowers produce as little as 65-85 decibels", without saying how or where that was measured. Our lawn mower guide shows where these sit among other brands.
Automower pages print a single row, "Sound level perceived". The manuals define it: their sound data are "Determined according to Directive 2006/42/EC and standard EN 50636-2-107. Except Sound level, perceived that is measured according to ISO 11094:1991." By that perceived level in the current US manuals, quietest first:
- Automower 420 iQ: 56 dB(A) (US page: 62)
- Automower 410 iQ and 440 iQ: 58 dB(A) (US pages: 62)
- Automower 435X AWD and 435 iQ AWD: 60 dB(A) (US pages: 60)
- Automower 535 AWD EPOS: 63 dB(A) (US page: 60)
- Automower 560 EPOS: 64 dB(A) (US page: 64)
- Automower 580 EPOS: 68 dB(A) (US page: 66)
- Automower 580L EPOS: 69 dB(A) without wheel brushes, 73 with them (US page: 72)
At the operator's ear the manuals list 47 dB(A) for the 420 iQ, 49 for the 435X AWD and 435 iQ AWD, 50 for the 410 iQ and 440 iQ, 54 for the 535 AWD EPOS, 56 for the 560 EPOS and 59 for the 580 and 580L EPOS, or 64 for the 580L with brushes, each with an uncertainty of 2 to 4 dB(A). Only the 435X AWD and 435 iQ AWD manuals print a guaranteed sound power, 62 dB(A) for both. The Ceora has no figure on its page. The 535, 560, 580 and 580L EPOS pages show no price and are sold through dealers.
Husqvarna's Automower manuals add a note worth knowing: "The first weeks after installation the sound level when the product cuts the grass can be higher than usual. The sound level decreases after some time." Our robot mower guide compares these with other brands' robots.
At the operator's ear, from Husqvarna's US pages, quietest first: 110iL FLXi 73.4 dB(A); 520iLX 76; 525iLST 80; 122L and 122LX 85; 525iLK 86; 122C 88; 122LK 90; 525LK 94; 330iKL 94.3; 430LS 95; 130L 95.4; 330LK 96.1; 130C 97; 522L, 525L, 525LS and 525LST 98; 535LK, 535LS and 535LST 100.
By guaranteed sound power: 520iLX 89 dB(A); 110iL FLXi 92; 525iLST 93; 525iLK 95; 122LX 102; 122C 104; 525LK 106; 525L and 525LS 107; 122LK 108; 522L 110; 535LK 111; 525LST and 535LST 114; 130L, 130C, 330LK, 430LS and 535LS 116. The 122L page prints a guaranteed "0 dB(A)", an obvious error, and the 330iKL kit prints no guaranteed figure. Combi kits sold with other attachments list their own ear figures: the 330iKE edger kit 80.5, the 122LKP pole saw kit 89.2, the 122LKH hedge kit 89.6, the 122LKE edger kit 93.3 and the 330iKP pole saw kit 95.1. The 330iKL figure is high for a battery tool and we report it as printed. Our string trimmer guide ranks these against other brands.
Our guide to the quietest cordless string trimmers ranks the 520iLX and 110iL FLXi beside STIHL's and Worx's battery trimmers on the same guaranteed figure.
At the operator's ear, quietest first: 115iHD55 78 dB(A); 520iHT4 80; 522iHD60 and 525iHF3 81; 520iHE3 84; 525iHE4 86; 525iHE3 89; 525HF3S 92; 522HD60S, 522HDR60S, 522HDR75S and 522HS75S 93; 122HD60 94; 525HE4 95; 525HE3 96; 322HD60 98.
By guaranteed sound power: 115iHD55 90 dB(A); 525iHF3 92; 520iHT4 94; 520iHE3 and 522iHD60 95; 525iHE3 and 525iHE4 99; 122HD60 101; 322HD60, 522HD60S, 522HDR60S, 522HDR75S and 522HS75S 102; 525HF3S 105; 525HE3 and 525HE4 107. The 320iHD60 Hedge Master prints neither. Our hedge trimmer guide has the cross brand view.
Battery saws at the operator's ear, quietest first: 125i Power Axe 84 dB(A); 225i Power Axe 89; 435i 90; 350i Power Axe, 542i XP, 542i XP G, T542i XP and T542i XP G 91; T540i XP 92; 550i XP and 550i XP G 94; 540i XP 95; 535i XP 97; T535i XP 99.
Gas saws at the operator's ear: 120 at 95 dB(A); T525 98; 130, 135 Mark II, 435, 440, 3120 XP and T540 XP Mark III 102; T435 and 540 XP Mark III 103; 460 Rancher and 565 at 105; 445S, 450S Rancher, 450X Rancher, 545 Mark II, 555, 564 XP and 564 XP G 106; 455 Rancher, 550 XP Mark II, 550 XP G Mark II, 562 XP Mark II, 562 XP G Mark II, 572 XP and 572 XP G 107; 365 X-Torq and 372 XP X-Torq 110; 585, 592 XP and 592 XP G 112. The ranges overlap: the gas 120 lists less at the ear than the battery 535i XP and T535i XP.
By guaranteed sound power, across all saws: 125i Power Axe 95 dB(A); 225i Power Axe 100; 350i Power Axe 102; 435i and T540i XP 103; 542i XP and T542i XP 104; 540i XP 106; 550i XP 107; 535i XP 108; T535i XP 109; T525 111; 540 XP Mark III and T540 XP Mark III 112; 435, 440 and T435 114; 455 Rancher, 460 Rancher, 545 Mark II and 555 115; 120, 130, 135 Mark II, 3120 XP, 445S, 450S Rancher and 450X Rancher 116; 550 XP Mark II 117; 562 XP Mark II 118; 365 X-Torq, 372 XP X-Torq, 564 XP, 565, 585 and 592 XP 119; 572 XP 120. Our chainsaw guide compares them with other brands' saws.
What moves the numbers inside Husqvarna's range
- Battery or gas. Within every tool type, Husqvarna's quietest battery model lists lower ear and guaranteed figures than its quietest gas model, though the ranges overlap among chainsaws. Husqvarna puts it as "The noise level from our battery machines are up to 13 dB(A) lower than a petrol machine".
- Speed setting. Boost mode raises the guaranteed figure by six decibels on the 230iB and nine on the 350iB, and the 525iB Mark II manual gives 64.4 dB(A) at 50 ft in normal mode against 66 in Boost. On trimmers and hedge trimmers, Husqvarna says savE mode "reduces noise levels" by "lowering the rpm".
- Size and duty. The 12 inch 125i Power Axe lists 84 dB(A) at the ear; the 70 cc class 572 XP lists 107. The 420 iQ Automower lists 56 dB(A) perceived; the 580L EPOS for sports turf lists 69.
- Accessories. The 580L EPOS manual lists four decibels more perceived noise with wheel brushes fitted.
Roughly every 10 decibels sounds twice as loud, so a 76 dB(A) trimmer sounds about half as loud at the ear as an 86 dB(A) one. Husqvarna's own pages say "A reduction of 3 dB(A) is usually perceived as a halving of the noise level", which describes sound energy rather than how loud it seems; most people need about 10 decibels before a sound seems half as loud. Our decibel chart places these figures among everyday sounds.
We did not measure any of these tools. Every figure on this page is Husqvarna's own, quoted from its US product pages and US operator's manuals as read on October 4, 2026, with the condition each describes, and ranked only against figures of the same kind within the same tool type.
