You probably know the stereotype of "snarling" refrigerators of Soviet times? Another way to call the sound of the work of their engines and the language did not turn. But those "terrible" times have sunk into oblivion. Now the permissible noise level of the refrigerator is much lower. But the most quiet and modern models sometimes work very noisy. Let's figure out how you can reduce the noise from the refrigerator, what norms and standards regarding the noise level exist today.
Modern standards
If you adhere to the current legislation, the permissible noise level from the refrigerator (in decibels) can vary from 25 dB to 50 dB. The noise level is divided into three categories:
- 25-34 dB - is considered the lowest noise level of the refrigerator;
- equipment with a noise level of 35-44 dB is classified as an average noise level;
- Devices with a noise level higher than 45 dB are classified as high noise generators.
And even the sound of the refrigerator above the regulatory limits can indicate a factory marriage in the unit or that it went out of order. If, in your opinion, the noise during the operation of the refrigerator is very strong, then it is recommended to measure with a special device a sound level meter. Let's find out how to do it right.
Measuring the noise level
Measurement of the noise of the refrigerator is carried out if your refrigerator unit worries about your too loud work. For this measurement, a rather expensive sound level meter is required. Buying for one measurement is rather impractical, so it makes sense to invite a specialist from the relevant institutions (Rospotrebnadzor, for example). Its call and paid, it will in any case be cheaper than buying a device for a one-time measurement.
Well, if you have such a device, we first set it up
A loud noise can indicate both the malfunction of the compressor of the refrigerator, and even that it is simply not level. From this, it is worth starting your "investigation". You need an ordinary water level. First we measure the position of the aggregate along, and then across. Adjust the angle with the help of screw feet. As a rule, the sound disappears if the refrigerator is set correctly. But if the noise level after this procedure is high enough, then this is the reason to contact the service center.
