Goodbye to the noise of the washing machine
With the production of the silent washing machine technology crosses another frontier, definitively overcoming the problem of high noise of an appliance that, together with the refrigerator, is considered the main household aid.
It took several decades of research to prepare suitable remedies to contain, within minimal limits, the annoying noise that it generates during operation, especially in the washing phase and in that of centrifuge.
Theoretically, for a washing machine to be defined as silent, it should not exceed 70 dB in the phase of centrifuge e 50 dB in the phase of wash.
Today it can be said with satisfaction that these ideal values have been practically achieved in factual reality so that the precious work of these machines is carried out with greater effectiveness and absolute discretion.
How silent machines came about
The levers on which one has acted to conceive silent washing machines there are basically three: inverter motor, direct drum drive, sound-absorbing materials.

But what is a inverter motor?
In broad terms it is an electronic rather than a mechanical motor.
Substantial difference that allows it to rotate by means of magnetic induction avoiding the friction produced by the brushes, elements present in motors (AC) powered by alternating current.
This results in less vibration and noise. The inverter also allows the optimization of current consumption on the basis of the different washing phases.
Another step forward towards the silence of the latest generation washing machines is the direct drive of the basket: a completely innovative mechanical system made it possible to connect the basket directly to the motor eliminating the critical belt drive.
A significant contribution comes from the use of sound absorbing materials that is, of materials whose characteristic is the presence of a high value of the absorption coefficient in certain frequency ranges. This allows for effective sound insulation.
Whirlpool washing machine
Among the low-noise washing machines, the Whirlpool Supreme 8415 occupies a place of absolute importance. In this regard, the numbers that distinguish it: 66 dB in centrifuga e 48 dB in washing, they are more than eloquent.

Wrong’soundproofing what gives this machine an extraordinary silence is not its only merit.
To it are added several others such as theenergy efficiency (class A +++ – 50%); the particular technology 6th SENSE that adapts the wash cycle settings to the characteristics of each load; the two technologies SprayWash e Sprayrinse: the first consisting in a direct nebulization on the garments of a mixture of water and detergent for a more effective removal of stains, the second consisting in an innovative rinsing by means of powerful and precise jets of water.
Technology SoftMove which adjusts the movements of the basket according to the type of fabric; not to mention the technology AutoDose, thanks to which it is no longer necessary to add detergent from time to time since this is sufficient for well 20 washes.
Bosch washing machine
In the pantheon of the best silent washing machines finds its place there BOSCH Standard WAT28639IT produced by the over one hundred year old German brand.

Energy class A +++, 9 kg load capacity, Inverter motor, iDos technology (automatic dosing system that measures the right amount of detergent, softener and water needed for each wash), Noise level 75 dB, Program AllergyPlus (specific for allergy sufferers), SpeedPerfect system (perfect clean with washing times reduced by up to 65%), Wave ™ basket (gentle washing thanks to the special structure of the basket).
In addition anti-vibration side walls, which enhance the acoustic insulation even during the spin cycle, are the important credentials thanks to which the WAT28639IT is accredited on the market, winning the decisive favor of the consumer public.
AEG silent washing machine
Always washing wool and delicates separately, preferably by hand, is a recommendation that still holds today.
AEG seems to have embraced this invitation when designing the series 7000 L7FE842.

In fact, this machine puts in the washing the same care and delicacy dedicated to hand washing. It is the function that makes this possible ProSteam® can be activated at the end of the wash cycle which reduces creases up to 30% as well as the steam program delicate that refreshes the fabrics and eliminates odors.
There are several other reasons to praise the performance of this washing machine.
The ProSense Tecnologyfor example, a program that automatically weighs each load to set a specific cycle.
Or his exceptional silence: 75 dBA in centrifuga or the great one display con touch control which allows setting and control of the various functions, as well as the option Soft Plus which prepares the garments for washing by evenly distributing the softener over the entire load.
Miele silent washing machine
Miele & Cie. KG, for those unfamiliar with it is a German company that is more than a hundred years old manufacturer of household appliances based in Gütersloh.
Very active in the washing machine sector, among others it proposes the WSA 033 WCS Active, a machine that resists the wear and tear of time.

Equipped with a honeycomb basket which lets the laundry slide on a thin layer of water ensuring a particularly delicate washing of the garments.
Among the most interesting features is the program Express 20″ which returns in a few minutes a freshened laundry, obviously when the garments are few and not very dirty.
The function is also very popular CapDosing which allows you to dose special detergents, softener and additive. The use of the machine is particularly simple and intuitive thanks to the sensor keys EasyControl.
Therefore a very respectable endowment. But the real strength is the Inverter motor with ProfiEco technology which guarantees intense, silent and economical washing for a long time.
Samsung washing machine
In the category of the quietest washing machines among those on the market, the Samsung WW90M644SBW, a machine with truly remarkable performance characteristics.

The basket can boast remarkable innovations from a technical point of view: the double movement QuickDrive and technology BubbleCARE.
The first ensures a dynamic movement of the laundry by moving it back and forth as well as rotating it in the washing tank; the second consists in adding further holes strategically placed in order to speed up the spinning phases and create a water cushion that protects the garments from that violent shaking that reduces their duration.
Last but not least the technology Stains Tutto Plus designed to remove the most stubborn stains. In practice it is the addition of a soaking phase to the program set by pressing a button so that the Ecobubbles easily penetrate the fibers of the garments, removing the most difficult stains.
