Recently, the Whirlpool AWE 9630 was called the quietest washing machine. With pride, the sellers reported that the acoustic level of the spin mode does not exceed 72 dB, and the washing is accompanied by noise of 51 dB.Today, AEG exhibits products that are superior to the Whirlpool model in this plan. It seems that manufacturers do not strive to achieve unprecedentedly low indicators. The quietest washing machine today is characterized by numbers of the former order. But the number of models providing quiet performance has increased.
Noise
The question of where the noise comes from is not as trivial as it seems. Obvious sources:
- water and laundry in the drum;
- moving mechanisms;
- sound service signals.
So the idea of noise advertising presents. In practice, the differences are noticeable. When washing in the different ends of the apartment, an unpleasant low rumble is heard before the ears. From the neighbor's washing machine, the house shakes, dust rises into the air. This situation is especially fraught with allergies. The advertisement did not say that the house will dance!
There is a feature known only to customizers of household equipment and technically enlightened owners of washing machines. Before using the device, you need to adjust it - install it on a building level in two horizontal planes, perpendicular to each other. Without tuning the noise will occur without fail, plus the washing machine will go on a journey. He will jump on the slope of the floor level, he will start to beat the walls and throw off things that are set on top. This is where the noise and crash, not described in the instructions.
The painstaking process of leveling the washing machine is done by adjusting the legs. It is easier to do along the diagonals: the first is aligned first, then the second. The level is placed on the upper horizontal cover of the washing machine. There are models where conditions are impossible. Look for alternatives.
Only the correct positioning of the washing machine will ensure complete silence and security.
How the AWE 9630
Works A quiet Whirlpool washing machine has long been considered the limit of excellence in terms of noise. Vertical loading in combination with ZEN technology are considered key features of the model. The idea is to eliminate unnecessary parts with a direct drive engine. The logic is simple: fewer moving parts - less noise. Excluded motor pulley and belt drive. The spinning washing machine works at 1200 rpm with a volume of 72 dB.
The manufacturer claims that, thanks to progressive technical progress, the washing machine consumes 20% less energy( class A ++).The newest feature was the Sixth Sense option. Load sensors determine how much laundry is placed in the drum, the further work cycle is determined based on the information received. Measured:
- amount of water;
- speed;
- temperature regimes.
The specified factor squeezes the maximum out of the washing machine. Naturally, there are manual settings.
Additionally, Night washing mode will save. The washing machine will do the work quietly, and the spin is turned on when everyone in the house wakes up. A special feature of the option is the fact: after the final rinse, the water does not drain. This circumstance has to be taken into account; not long laundry will benefit from prolonged soaking. This prevents the formation of folds that appear without fail if removed from the water.
14 washing modes allow you to choose by type of fabric products, by color. This is a good idea, the main thing is not to fill the washing machine with things of different colors. At a cost of $ 700, the device has 4 saving modes. Choose the one you like.
A little about the numbers
Silent washing machine W6984 S from the company ASKO is characterized by the parameters of work / spin 46/75 dB.Better or worse than the above criteria? At the same time, a model with lower turns will provide the owner with a ratio of 45/72.Finally, the newest washing machine flaunts with the number 54/75.It turns out that the sound level is not recognized as a key when constructing a modification.
The Bosch website offers the reader three types of washing machines:
- Vertical loading;
- Horizontal loading;
- Embedded.
As it turned out, Bocsh does not indicate the noise level of washing machines at all. But in an indispensable order supplies the parameter instructions for refrigerators. Reason of apparent neglect: a common standard has been developed that regulates the operating parameters of washing machines. In Russia, it is MsanPiN 001-96.According to the recommendations, the limit of noise for “durable products”, and devices that operate for 1–6 hours, is 75 dBA.
The indicated figure is marked in the spin mode of most washing machines. Therefore, in the Russian market it is impossible to meet washing machines of legal circulation with worse parameters. This is against the law.
A bit of physics
With what to compare the noise of washing machines?45 dBA - what does this mean?
A conditional parameter is known - the threshold of hearing of the ear. The value is conditional, because people have different hearing. The threshold is usually characterized by a sound pressure of 2 · 10-5 N / m2 for a frequency of 1 kHz. The conventions are introduced when ear sensitivity is a curved line that is uneven in level.1 kHz roughly corresponds to the note C of the second octave. This is a high sound that is beyond the power of squeezing out a standard male throat.
The letter A stands at the end of the relative measurement value - decibel - not by accident. The letter helps to distinguish the parameter from the list of other branches of physics. Decibel is a popular value used in many practical applications.“A” unambiguously denotes acoustics dBA.In the course of the text, the letter A is sometimes missing to simplify the recording, when the context is obvious.
Wash
It is believed that in the average room the sound level is 35 dBA.If you stand right next to the washing machine, you can hear it. It is believed to recall that the place of installation of the device is at some distance — the kitchen, the bathroom — and to make amendments.
While the sound comes into the room, it is weakened by walls, the chances that the washing machine will start to bother are relatively small. Compare with another technique. There is often a refrigerator in the kitchen. A typical Bosch unit operates at a volume of 42 dB, it is more often heard only at night with the doors open. Washing machine with a volume of 45 dB, obviously, does not disturb the calm of the household.
Spin
75 dB - a decent value, corresponding to a noisy street. LG washing machines have a feature: in the spin mode, the noise level is noticeably lower than that of other manufacturers. This improvement is achieved at the cost of increasing the volume of the standard washing process.
The achievable spin value is 63 dB.This means that the washing machine produces four times less noise than is regulated by the standard. So much incident with a difference of 12 dB( 75 - 63).According to customer reviews, LG washing machines are really quietly squeezed. The volume of the operating mode, respectively, 3.5 - 4 times higher than that of competitors.
Spin or wash
Considering the above, it is necessary to understand: at the present stage of development, the simultaneous reduction of the noise level in all modes of operation is unattainable. Quiet washing machines will provide the wearer with either a spin or a low volume wash.
And there is no noticeable special struggle for noise reduction. And what do giants consider important?
Rumor has it that AEG representatives showed a curious trick during their ad impressions. A bouquet of roses was put in the drum. Careful wash mode laundered fragrant flowers for a set time, then followed by spinning at 1600 rpm. A bouquet from the washing machine turned out to be possible to give to any girl.
Savings are so familiar to modern appliances that each washing machine demonstrates special modes. Available in models that save up to 30% of washing powder. Over 5 years of operation accumulates a considerable amount. Do not forget about electricity, water, subject to savings.
Conclusion
Silent washing machine is selected comprehensively. If everyone in the house is sleeping, Night Wash will not disturb sleep. When the apartment is full of cheerful, cheerful people, the spin will not spoil the mood.
Equipment is selected taking into account the features listed above. Peace will remain, and the equipment will function properly.
