A quiet refrigerator is usually below 40 dB(A). For an open-plan kitchen, a studio or a very quiet room, 35 to 38 dB(A) is a better target. Above 40 dB(A), the noise may still be acceptable in a separate kitchen, but it is much easier to notice at night or near a sofa.
The decibel figure does not tell the whole story. A steady hum at 39 dB can be less annoying than a lower but irregular click. You need to look at the energy label, the cooling system, the installation and the real sound character of the appliance.
Simple buying benchmarks
| Noise level | Practical interpretation |
|---|---|
| 34 to 36 dB(A) | Very quiet, good for studios and open-plan kitchens |
| 37 to 39 dB(A) | Quiet for most homes |
| 40 to 41 dB(A) | Acceptable, but audible in a calm room |
| 42 to 43 dB(A) | Avoid if you are noise-sensitive or the fridge is near living space |
| Over 43 dB(A) | Often noticeably loud for a calm home |
The Swedish National Agency for Public Procurement, using the European energy labelling framework, sets example noise requirements of 41 dB for refrigerators and 43 dB for some automatic-defrost fridge-freezers. It also notes that noise class C covers the 36 to 41 dB(A) range on the energy label. Those figures are useful, but if comfort is the priority, aim for the lower end of that range.
Why a few decibels matter
The decibel scale is logarithmic. An increase of 3 dB is roughly a doubling of sound intensity, although the human ear does not experience it as exactly twice as loud. That is why the difference between 36 and 39 dB(A) can be noticeable in a quiet studio.
Useful comparisons:
- 30 dB: whisper or very quiet room.
- 40 dB: quiet library.
- 50 dB: low conversation or calm office.
- 60 dB: normal conversation.
A refrigerator runs day and night. Even a low sound can become tiring if it is irregular, if it vibrates through the floor or if it starts near a sleeping area.
Reading the energy label correctly
On refrigerators sold in Europe and Switzerland, the energy label shows annual consumption, useful volume and airborne noise in dB(A). The European Commission states that suppliers must provide the label and product information sheet for refrigerating appliances. For noise, the most useful item is the exact dB(A) value, not only the class.
Be careful with old A+, A++ and A+++ references: they are no longer the right language for comparing current models. Use the current label scale and compare two concrete numbers: kWh/year for energy and dB(A) for noise.
What makes a fridge noisy
The value on the label is measured under standardised conditions. At home, several things can amplify the sound:
- Tight installation: an appliance touching a wall can transmit vibration and ventilate poorly.
- Uneven floor: a badly adjusted foot can cause humming or knocking.
- No Frost cooling: the fan can add an audible airflow, even though the technology is convenient.
- Ageing compressor: a worn compressor can become louder over time.
- Temperature set too low: an excessive setting makes the appliance run longer.
- Dusty condenser: heat escapes less efficiently, increasing running time and sometimes noise.
If your fridge is mainly loud at night, see our guide to fridge noise at night. If the noise is continuous, the diagnosis is different and our article on refrigerator noise causes is more relevant.
How to choose a quiet refrigerator
Start by choosing a realistic threshold:
- Studio, open-plan kitchen or bed nearby: aim for 35 to 38 dB(A).
- Semi-open kitchen: aim below 40 dB(A).
- Separate kitchen: up to 41 dB(A) may be fine if reviews confirm a steady sound.
Then look at the technology. An inverter or linear compressor can reduce abrupt starts because it adjusts output instead of cycling sharply on and off. It is not a guarantee of silence, but it is often a good sign when the dB(A) value is low.
Also read user reviews for the type of sound: vibration, clicking, fan noise or gurgling. Reviews are less reliable than the label for measuring noise, but they reveal irregular sounds that the official figure does not describe.
Reducing noise from an existing refrigerator
Before replacing an appliance, check these basics:
- Adjust the feet so the fridge is stable and very slightly tilted backwards.
- Leave the ventilation space required by the manual.
- Move the appliance away from the wall if it touches a skirting board or cabinet.
- Clean the condenser if your model allows it.
- Check that shelves, bottles and drawers are not vibrating against each other.
- Avoid excessive cold settings: SwissEnergy indicates that 7 °C is enough for the refrigerator to save energy, and -18 °C for the freezer.
An anti-vibration mat can help if the sound comes through the floor, but it must never block ventilation. If the compressor clicks loudly, overheats or runs without stopping, call a professional or compare the symptoms with our guide to signs a fridge is beyond repair.
In short
For a genuinely quiet refrigerator, look for less than 40 dB(A), ideally 35 to 38 dB(A) in an open room or small home. The noise class and energy label are useful, but comfort also depends on installation, sound character and maintenance. A well-installed, well-ventilated appliance with a stable hum will often feel quieter than a model that is only "quiet" on paper.
