Noise Level

Noise level refers to the sound level emitted by an appliance during operation. This value is measured in units called decibels, abbreviated as “dB.” A decibel is a unit for measuring sound intensity. To give you a better idea, a whisper is approximately 20 to 30 dB, while a normal conversation is around 60 dB. The sound of an appliance is most often produced by a motor, compressor, or fan, depending on the type of appliance and its design. A lower decibel value means the appliance operates more quietly. This information is important when selecting an appliance for quiet spaces, such as bedrooms, children’s rooms, or offices.

To better visualize the noise level, a comparison with common household appliances may be helpful:

• 25–35 dB – almost inaudible (e.g., some air purifiers in night mode)
• 35–45 dB – very quiet (refrigerators, dishwashers on night mode)
• 45–55 dB – quiet (standard dishwashers, washing machines during the wash cycle)
• 55–65 dB – typical noise level (washing machines during the spin cycle, range hoods on lower settings)
• 65–75 dB – louder (most vacuum cleaners, high-powered range hoods)
• 75–85 dB – high noise level (blenders, food processors, some garbage disposals)
• 85 dB and above – very high noise levels (gardening equipment, power tools)

Before purchasing an appliance, it is therefore advisable to check the noise level in the technical specifications and compare it with this guide—especially if the appliance will be used in a room where quiet is important.
