Level the refrigerator noise: why the device buzzes, and how to choose the quiet?

The really "loud" refrigeration equipment for the majority of people just left in a not very pleasant memories. Now even modern models consumers are quite picky in this matter. And no wonder, because it is - one of the devices, which operates around the clock, and it is desirable that the level of noise created by the refrigerator a minimum of discomfort.

Which is why it makes a noise?

modern refrigerators operate relatively quietly, however, they are characterized by a wide range of sounds. Why? This is due to the fact that the device is equipped with multiple systems at once, performing different functions. refrigerator noise can create the following items:

• Compressor - is the most popular to date system that allows you to preserve the freshness of the products. Compressor unit circulates coolant from this technique is buzzing, plus the vibration transmitted to the body.
• Refrigerant - refrigerant cooling process that takes place in special tubes, causes a whole range of sounds: gurgling, shimmering, humming, and even howl. These sound systems both for characters with Freon, as well as for application to gas installations.
• Relay - the mechanism responsible for switching on and off of the compressor of the engine, it produces clicks and pops.
• System No Frost - even the quietest fridge with such a function has a special fan that simply can not work silently.

Devices with automatic defrost publish additional characteristic sounds. By the way, the freezer also has its own fan, which gives itself felt monotonous hiss.

Standards noise measurement method and refrigerators

Measured level of sound in decibels (dB). According to accepted standards indicator must be in the range of 25 to 50 dB. Low level of 25-34 dB is considered, medium - 35-44 dB. If the refrigerator noise exceeds 44 dB, a level considered high.

Sometimes excessive sound indicates a malfunction of the compressor and workmanship in the equipment. Therefore, if the unit is running suspiciously loud, you want to measure the noise level and to compare it with these statements. You can find them in the manual or on a sticker manufacturer. For measurements should call a specialist, it's much cheaper than buying a sound level meter. The procedure is as follows: the device is adjusted to the range of 50-100 dB, is directed to a technique to monitor the appearance of noise performance of the refrigerator. It is important that the sound level meter was not closer than 50 cm away from the man.

Methods for removing noise

Often it turns out that the noisy fridge for the most trivial reasons. In such cases, you can try to fix the problem yourself using the following methods:

• Align the surface on which the device (preferably in level).
• Check does not concern whether the wall appliances, furniture, pipes or other equipment and move it if necessary.
• If one of the camera is not in use, it should be turned off.
• For the isolation of "high-profile" elements, you can use special sound-absorbing panels.
• The inner walls of chambers recommended to cover the sound insulating material.

Besides, the refrigerator can be put on the web, which absorbs sounds. Covering device for a wall portion of the porous rubber to help avoid additional reflection of sound waves.

Rules of proper choice of the refrigerator

To purchase a really quiet refrigerator, enough to be guided by simple rules. Firstly, it is worth spending the time and ask the consultant about the level of noise of the compressor in operation, this data must be indicated in the instructions. Relatively quiet installation work with the figure of 30-40 dB.

The second thing you need to pay attention to is the number of compressors. Unlike two-compressor units is that they are often included as separate units operate alternately. But abuzz this technique is much less, as each compressor cools a small volume and spend less effort - an experienced consultant will recommend to choose this model.

Another factor that determines the volume refrigerator works, - No Frost system. This is a convenient invention of modern times is in great demand among consumers. But it should be understood that installation work No Frost provides a fan, so these refrigerators offer substantially more noise.

Top 8 noiseless refrigerators

If you rely solely on the will look like objective review, the users themselves, a list of silent coolers:

1. Liebherr. Praises are most often found in the address of the units of the Austrian, Belgian and Bulgarian assembly.
