Can neighbors hear my washing machine? Quiet apartment guide

A washer's spin is the noise most likely to reach the flat below, and it gets there as a shake through the floor more than as sound in the air. By Bosch's own sheets, its compacts wash at 51 or 52 dBA and spin at 72 to 75. Even the 72, the lowest spin number on any washer we list, is louder than normal talk, which the NIDCD places at 60 to 70 dBA.

An apartment changes the noise question. In a house, a loud machine mostly bothers the people who bought it. In a flat, the washer sits in a closet off the hallway, the dishwasher runs against a wall someone else sleeps behind, and your floor is another person's ceiling. Every machine has two audiences: you, and the people next door and downstairs.

This page ties our apartment guides together and covers noise only. Leases, building rules and noise ordinances are for your lease and local rules to settle.

How quiet should an apartment be?

No official figure exists for an apartment, so the reference points are the ones for any home.

Loudness does not climb in step with the number. According to the National Park Service, 10 dB more means twice the perceived loudness, which puts 40 at roughly double 30.

Those levels describe a whole room. A maker's figure describes one product, at a distance the maker almost never states, and it is good for setting products beside each other and little else. For the same reference points room by room, see how quiet is quiet enough.

Downstairs neighbors feel more than they hear

A dBA figure describes sound in the air: the hum of a fan, the spray of a dishwasher, the whine of a vacuum motor. Walls and closed doors cut that down, and most of it stays in your rooms.

Vibration is a different path. A washer shaking on its feet during the spin, or a foot landing on a treadmill deck, passes into the floor and the walls and arrives next door as a thump. No figure on the box describes it, which is why the manuals put so much of the fix in installation: shipping bolts out, feet levelled, the machine set down on a firm surface or a dense mat.

Which appliances do neighbors hear most through shared walls and floors?

Three noises do most of the travelling: the washer's spin, footstrike on a treadmill, and the burst when a robot vacuum's dock empties.

Laundry

The spin is the part of a wash that carries to the flat below, and the washing machine guide's advice for apartment dwellers starts from it. That section weighs turning the spin speed down against wetter laundry, and covers how the machines react to an uneven load, what the makers say about wooden floors, and which run on a standard 120 V outlet.

Dryers are quieter to shop for, if only because there is less to compare. Every dryer with a maker figure in the quietest dryers is a 24 inch compact, no full size dryer publishes a number at all, and the guide sets heat pump against vented compacts and notes which ships with its stacking kit. For a stacked closet near a bedroom, the compact dryer guide adds the closet door, the long heat pump cycle, the end-of-cycle chime and the plug each one needs.

A flat with no dryer vent may end up with one drum doing both jobs in a closet. The apartment section of our washer dryer combo guide covers that case.

Treadmills and walking pads

What carries through the floor is the thud of each footstrike, not the motor's hum. The quietest treadmills for an apartment builds on that: walking is gentler than running, a dense rubber mat beats thin foam or plush carpet, and the published walking pad figures cannot be put in order.

Under a desk, things are not much better. The walking pad guide finds the figures that come with a stated condition sitting at 65 to 70 dB, higher than the bare claims, and that on a wooden floor even a quiet pad can still thump.

Robot vacuums

In everyday modes the robots list 52 to 65; the self-empty dock, where a maker gives a figure for it, lists 70 to 78.9. That short, loud burst is more likely to reach a neighbor than the quiet-mode hum, and the robot vacuum guide's notes for apartments start there before moving on to what each brand's do-not-disturb setting actually blocks, plus voice prompts, carpet boost and the dock's footprint.

Dishwashers

The quietest 18 inch dishwashers for an apartment ranks compact built-ins dBA against dBA, with delay timers, run times, which models let you mute the beeps, and the hookups a rental sink cabinet already has. A kitchen with no hookup at all points to the quietest countertop dishwashers, which compares faucet-connected and rolling portable models, explains why their figures cluster so tightly with no method given, and says how to check your faucet first.

Where the kitchen opens onto the living room, our page on planning a quiet open-plan kitchen brings in the fridge and the hood.

Few machines print a figure for the noise neighbors hear

Across the washers, robots and treadmills we list, 10 of 28 washers give a spin figure, 10 of 47 robots an emptying figure, and 1 of 33 treadmills a loaded figure. The counts cover what we listed on 2026-10-26, not the whole market. Each product's noise line was sorted by the part of the cycle, mode or load its maker says the figure describes.

Washers first. The 10 spin figures come from five brands, all in dBA, from 72 for Bosch's 300 Series to 80 for Midea's MLTW45M4BWW top loader. Four more washers print a figure for washing or a quiet cycle only, such as Speed Queen's 43dB during agitation. One Midea prints 80 dBA without naming the half of the cycle, and 13 print no number at all.

Robot docks are dominated by one brand. Eight of the 10 emptying figures belong to Ecovacs docks, listed from 70 dBA for the T80S Omni on its quiet setting to 83 dBA for the N30 Pro Omni. Roborock gives the Qrevo Curv 2 Flow 70 dB and says the burst "lasts less than a minute"; Dreame gives the D30 Ultra 78 dB. A Dreame figure its maker calls an estimate was left out, and so was a Roborock image that prints a number without saying what it measures.

Treadmills and walking pads are the thinnest. Of 33, 28 print a figure, and 9 say in writing that it was taken with nobody on the belt. Only Technogym's Run gives a loaded figure, "57 dB at a 10 km/h speed (on average - 85kg user)". Eleven maker documents add that the noise rises once someone walks or runs.

Not one of the 108 products publishes a number for footstrike or spin vibration arriving through a floor. The guides lean on mats, levelling and timing for that reason.

The machines you hear from your own rooms

Inside the flat, check the air conditioner, the dehumidifier, the air purifier, the fan, the stick vacuum and, in a studio, the mini fridge.

Air conditioning

The quietest window AC for a bedroom sizes each pick to the room, compares figures only at the same named setting, and reads the manuals for sleep modes, display lights and energy saving modes that restart the fan.

Where the building allows one, the mini-split guide's bedroom section covers the wall units their makers rate speed by speed, and the living room mini-split guide reads the larger heads at the low, medium and high speeds they run on while the TV is on.

A portable brings its compressor into the room along with everything else, as the portable air conditioner guide explains. Portables bottom out at 42 to 44 dBA in their published figures, at the lowest speed or in a sleep mode. Window units come out quieter by the makers' own numbers.

Dehumidifiers

On low, the quietest full-size dehumidifiers are listed at 43 dBA. The quietest dehumidifiers shows that units removing very little water account for the quieter-looking figures, and how to check capacity claims. Without a floor drain, the quietest dehumidifier for an apartment works out what a full bucket weighs and which pump units lift the water into a sink.

Air purifiers

The bedroom section of our air purifier guide deals with the settings you would sleep next to. On a budget, the under-$100 air purifier guide sets each unit's rated room size and yearly filter bill beside its noise figures.

Fans

What a tower fan's sleep mode really does, and which speed it holds once the lights go out, is in the tower fan guide's sleep mode section.

Stick vacuums

Just three makers name the power mode behind a figure. The cordless stick vacuum guide sorts every published number by mode anyway, then covers auto modes that ramp up on carpet and how to set a charging dock so it empties only when you press the button.

Mini fridges and freezers

In a studio a mini fridge may sit near the bed. Most brands publish no figure, the mini fridge guide finds, and a steady figure misses the compressor switching on at night; the guide also sets out how compressor, thermoelectric and absorption fridges each sound. The lowest published figure we found is 32.3 dB, for Summit's fanless CM42PL. For a student room, the dorm section of our mini fridge guide shows why that 3.1 cu ft model can fall foul of the strictest housing office size limit.

If a chest freezer has to live in the main room, the quietest chest freezers picks the Hisense WFC050M6XWD for an apartment, at 40 dB, and covers the levelling legs and wall clearance that decide how it sounds there.

The lowest figure in each guide

Each row gives the lowest figure among one guide's picks, with the setting the maker names. Units and conditions differ between rows.

Do not read down a column. A robot's 52 dB in Quiet Mode and a washer's 72 dBA spin come from different makers, units and settings, and the table is not in order of loudness.

Copy the condition onto your shopping list along with the number: the spin figure, the dock figure, the low fan figure. A machine whose maker prints none of them cannot be placed in its row at all, and each guide explains what those makers offer instead.

What time can you run a washer or dishwasher in an apartment?

Which hours count as quiet is a question for your lease and local rules. What you control is when the loud part of each cycle lands.

Start with what the timer sets. Bosch's washer timer, Finish in, sets the program end time, and the spin comes at the end, so a cycle set to finish early in the morning spins just before then. Set it to finish once the building is awake, or run it in the afternoon.

Dishwashers are a matter of run time. The 18 inch models in our guide run their Normal cycles for more than two hours, and a late start is still running well into the night. In a studio, a delay that runs it while you are out may be the quieter answer.

Do-not-disturb windows differ by robot. Some docks hold the emptying burst during the window and some only stop scheduled cleans, and a held dock leaves the bin full until the next clean.

Then the chimes. Through a shared wall, an end-of-cycle tone can carry further than the machine, and several washers and dishwashers in our guides let you turn it off.

Cabinet width, outlets, stacking kits and closet air

An 18 inch dishwasher has a smaller cabinet with less room for insulation, and the 18 inch figures run higher than full-size ones.

Power is the next limit. A standard 120 V outlet is often all an apartment closet offers, yet some compact washers need a higher-voltage circuit, and so do the compact dryers in our guide. If you rent, ask before you touch the wiring or the plumbing.

Stack only with the kit the maker names. Bosch says not to put a washer-dryer stack on a platform, because the pair may tip over, and our guide to the quietest stackable washer and dryer names the kit each pair needs. A closed closet door helps with noise too, but a stacked closet needs air. Plan louvered doors rather than leaving the door open.

How do you read an appliance decibel rating?

Three questions: which setting or cycle, dB or dBA, and how far away.

The setting comes first. A washer figure may be the wash or the spin, a robot figure quiet mode or the dock, an air conditioner figure low fan, sleep or a quiet mode, and a walking pad figure idle or under load. If the maker does not say, treat it as the quietest setting.

dBA, also written dB(A), is weighted to follow how people hear, and a dB figure should not be ranked against it. See dBA explained.

Distance is almost never stated. Inside an apartment's walls, OSHA notes, sound fades more slowly than in open space, since surfaces reflect it. Small gaps between brands mean little for the reasons in our page on setting one brand's dB rating beside another's.

A machine in the flat that has lost the quiet it once had is a different problem, covered in why your appliance got louder.
