What noise level should a refrigerator have?

The noise level during operation of the refrigerator is an indicator of the volume of its operation when performing its main tasks. According to GOST standards, the norm should not exceed 53 dB. According to the classification, indicators are divided into 3 types:

• 25 – 34 dB – low;
• 35 – 44 dB – average;
• 45 dB or more – high.

What influences the generation of noise during operation of the device?

Noise during operation of the refrigerator is generated as a result of the operation of:

• Compressor. It ensures the maintenance and formation of low temperature conditions. When turned on, it may come into contact with other parts and produce vibration noise.
• Refrigerant. When moving in the tubes, it makes sounds reminiscent of gurgling or gurgling.
• Relay. Every time it turns on and off it creates sounds similar to clicks.
• Fan. They provide a flow of cold air to the chambers, but at the same time create noise.

Reference! The two-compressor structure of the refrigerator produces much more noise than a standard single-compressor one.

Which refrigerator is the quietest?

A device that does not emit more than 40 dB during operation is considered silent. Unfortunately, the equipment cannot work below this mark.

The quietest option are models with a static or combined cooling system. They allow you to defrost the walls without human intervention. If the name contains the combination “Smart Frost”, “Low Frost”, “No Frost”, etc., then this technique will work quietly.

Which refrigerator is better?

Top 5 quietest models

1. Bosch KGS39XW20. It has a medium noise type and produces only 40 dB.
2. Atlant XM 6024–031. Two-compressor model, not exceeding 40 dB during operation.
3. LG GA-B489 YVQZ. Korean device producing 40 dB. Quiet operation is ensured by the presence of a linear compressor.
4. Samsung RL-59 GYBMG. The noise level produced does not exceed 38 dB. Additionally, it has a protection system against voltage surges in the network.
5. Electrolux ERN 29750. A silent, compact device that is perfect for small kitchen spaces.

What to rely on when choosing a device depending on the future purpose

Normally, a refrigerator should not emit more than 44 dB. Exceeding this value indicates that the equipment operates loudly and causes discomfort to its owner. To check the volume level of your future purchase, you should refer to its passport. In it, the manufacturer indicates the technical characteristics with the numerical value of the noise produced.

How to reduce the noise level of the device

Determining the cause of noise at home is easy. You may need a sound level meter for this. If you don’t have this, then in this case, contact specialists who will take measurements and give you the real test result. This service is not free, but it is several times cheaper than buying a sound level meter.

DIY ways to fix the problem

You can independently reduce the sounds of the refrigerator in the following ways:

1. Provide a level base under the refrigerator.
2. Adjust the height of the equipment legs.
3. Place dishes inside the refrigerator at a short distance.
4. Isolate parts that produce noise with special screens.
5. Cover the outer part of the chamber with noise-absorbing materials.
6. Move the refrigerator to such a distance that it does not come into contact with other appliances.

Reference! If you cover the place where the refrigerator will stand with a rubberized material, this will significantly reduce the volume of the device.

In what cases is it better to contact a specialist?

If you notice excessive noise generation in your equipment, then you can talk about a manufacturing defect or improper assembly of the equipment. Then you should seek help from an experienced specialist.
