Stairlift noise levels: how loud are they?
A current indoor stairlift is not a vacuum on the stairs. It is a battery chair on a rail. You hear a low hum while it moves, then it stops. Makers do not usually print a single decibel number. They describe the sound, the drive, and what it means if the chair gets louder later.

What the makers say about the sound
Our FAQ already says most current models run with a low, steady hum. Many run on batteries that recharge at the ends of the rail, which is also why they keep working through a short power cut.
Stannah puts a number on the comparison, not on the meter: because the chair is battery powered, it makes very little noise in use, "equivalent to the hum of a microwave." The same page says the lift beeps as it starts, on purpose, so people nearby know it is about to move.
Savaria calls the K2 quiet and smooth-riding, from a rack and pinion drive. Bruno's 2026 guide does not publish a decibel rating either. It does say indoor straight rails use a covered, inverted gear rack on the back of the rail, not an exposed rack, and a "soft start/stop" so the chair eases off at each end instead of slamming to a halt.
If someone quotes you a precise dB for "the average stairlift," ask where they measured it. Brand blogs disagree with each other. The brochure in front of you is the safer source.
What actually makes the sound
Most household chairs use a rack and pinion: a gear on the carriage walks a toothed strip in the rail. Stannah describes that setup in plain language on a questions page: motor in the base, gear on a geared strip in the track.
A covered rack, like Bruno's inverted gear, keeps grease and dirt off the stairs. It also keeps some of the click of the teeth inside the rail instead of out in the hall.
Savaria's Handicare 1100 is a different drive. It uses a patented four-motor friction system and no gear rack. Savaria says that gives a fully enclosed rail and a "super smooth ride with stop and start." Smooth is not the same as silent, but there is no metal rack for the gear to tick against.
None of those pages claim the chair is silent. A motor still hums. Rollers still meet the rail. If the stairs sit next to a bedroom, that hum is the thing to hear in person, not on a spec sheet.
Beeping is usually not the motor
A beep while the chair is parked is a different problem from travel noise. Stannah's troubleshooting page says a continuous beep often means the batteries are not charging. On a curved rail, charge points are usually at the top or bottom. If the chair did not finish its travel, it is not sitting on the charger. A hinged rail left down can also keep the lift beeping because it is treated as an obstruction.
If the chair has started making more noise than usual while it runs, Stannah wants a service engineer. They name the motor as one possible cause. That is the line between "this is how it sounds" and "something changed."
A dirty or dry rail can add scrape and rattle. Bruno wants the rail kept clean (not the gear rack) and an annual clean, inspect, and lubricate by a factory-trained dealer. The chores live in stairlift maintenance.
Nighttime and shared houses
The ride itself is short. Stannah's public-sector FAQ puts speed at a gentle walking pace, about 41 seconds one way on an average straight flight and 55 seconds on an average curve. You are not listening to a dishwasher cycle. You are listening to less than a minute of hum, plus that start beep if the model has one.
If someone sleeps next to the stairs, ask the installer whether you can hear a showroom chair, or a recent install of the same model. Drive type belongs on the quote next to brand and capacity. So does who services it when the hum turns into a grind.
Safety sensors that stop the chair if they hit something are a separate topic. See are stairlifts safe. Battery backup during a power cut is here.
What to compare on quotes
Ask each company:
- What drive does this model use (rack and pinion, covered rack, or friction)?
- Does it beep at the start of a trip, and does it beep if it is off charge?
- Who do I call if it gets louder six months in?
Photo quotes will not let you hear the chair. Once you pick a company, a short visit is the time to ask for a demo or a nearby install of the same model. You make that call. Nobody from the quote list has your number.
