Choosing a silent hood in the kitchen

All the problems of cleaning the air in the kitchen today are solved with the help of specialized household appliances - various types of hoods. They have significant differences in design and basic technical characteristics, but one of the selection criteria is a low sound exposure level. Can the device work silently? Consider what the quiet hood for the kitchen offers the market, and what is the principle of their work.

Functionality and noise

Every user knows that during operation exhaust systems create a certain noise, since the electric motor works, the fan rotates: they have not yet invented absolutely silent such units.

There are several key parameters that affect the creation of noise exhaust system:

• performance - the main parameter showing how many cubic meters of air the exhaust passes through the entire structure during an hour of work;
• the volume of the room where the kitchen is located - the larger it is, the higher the productivity should be;
• exhaust power depends on the size of the room.

As we can see, all these parameters are related to each other, they can be calculated using a simple formula - the height and area of ​​the room are multiplied by 12. It is the number of times per hour that the air during cooking should be completely updated according to all standards of the Russian Federation.

Often, the greater the power and performance of the device, the higher the level of noise generated by it.

If you plan to remove polluted air from the room, then the result should be multiplied by a factor of 1.3 - it takes into account the length of the standard duct, the depth of the mine, the height of the building.

For example, you live in a standard five-story building: the kitchen area is only 6 square meters. m., ceiling height of 2.25 m and you choose diversion option. Then we get 6 x 2.25 x 12 x 1.3 = 210.6 m³/ h - you need a hood with a capacity of at least 250 cubic meters. m. If you install recycling system, the result will be 162 m³/ h

Many users will ask - why do we need these calculations? They are made in order to find an appropriate exhaust system for your kitchen. When purchasing a hood, be guided by the desired performance and the level of noise produced at the same time.

Need to know that choosing a new exhaust system, its performance is taken with some margin to ensure normal circulation.

The conclusion here is quite simple: in practice, absolutely silent hoods for the kitchen do not exist. The whole trick of manufacturers is how to reduce the noise produced at work to a minimum.

Noise levels

Manufacturers strive to ensure that as soon as possible on the market appeared silent exhaust, and users are happy to install them in their kitchen. There are already specific developments in this area. For example, developed silent fans with unique engines: the noise from the operation of such an electric motor is practically not perceived by the human ear.

We are constantly surrounded by different sounds, and in order to get a little orient, we will give the power of the noises often encountered in our life:

1. Whisper at a distance of 1 m = 20 dB.
2. The rumble of voices in the auditorium of the theater is no more than 30 dB. This noise is considered the ultimate norm at night in a high-rise building.
3. Quiet talk up to 40 dB. Marginal daily rate for residential premises.
4. A conversation on high tones - 60 dB, the maximum allowable rate for a system of offices in Europe.
5. Noise impact from a brass band in a city park at a distance of one meter - 70 dB.
6. The sound of the movement of a heavy truck - 80 dB.
7. Working punch in the room creates noise up to 90 dB.
8. Peals of thunder, a maximum of 100 dB, experts say - this is the maximum permitted volume for high-end headphones.
9. Working jackhammer creates a noise impact of 120 dB.

The pain threshold for a normal person is within 120-140 dB, and the noise from the work of an ordinary kitchen hood is only 55-65 dB. Given that it does not work all the time, there is no particular impact on the hearing organs of the people living in the apartment.

Exhaust noise level

When buying, you need to ask not only the power and performance of the system, but also what sound effect it has on maximum speed. Such information is in the attached instruction manual.Many manufacturers make hoods of sound-absorbing materials, which decently reduces sound effects to acceptable decibels.

Here, the human factor still plays a huge role: for one, 55 dB sound is considered the norm, and in another family member this will be comparable to a toothache.

To choose for the kitchen, if not the noiseless, but the quietest hood, it is enough to follow very simple rules:

1. Never buy a hood with more power.
2. Try to choose a model whose maximum noise does not exceed 44 dB.
3. Take the model only with the mode control. According to experience, it will work extremely rarely at maximum modes.

Perform all types of maintenance in a timely manner, especially filter cleaning and the entire air duct. When they become clogged, the sound effect increases greatly.

Innovative Development

Excellent design, good power and performance - this is what any modern hostess of the quietest extracts can surprise. Such an acquisition allows you to watch your favorite TV shows or music programs while cooking, and talk with your friend on the phone.When there are small children in the house, you can cook during their sleep - fidgets will not interfere with the process, and the work of the hood will not interfere with their sensitive sleep. These hoods can be installed in rooms when the kitchen and living room are combined into one.

The system of corporate noise reduction NRS from the Italian company Falmec impresses with its technology and impeccable assembly. Kitchen hoods produce more than 85% less noise during operation than their counterparts from other manufacturers. The company's engineers did the impossible: they increased the efficiency of their operation and reduced their energy consumption.

Noise Reduction System NRS

The company constantly collaborates with laboratories where air flow dynamics is studied. The whole process of drawing, the movement of the air flow inside the structure were modeled using innovative computer software. With the help of modifications, various resistances on the way of movement, which create extraneous noise during the operation of the exhaust, were eliminated.

In the manufacture of the body and the main parts used sound absorbing materialsThat is why today users who have installed such exhaust systems in the kitchen enjoy absolute comfort.

The designers used several new, very interesting and non-standard solutions:

• exhaust fan it is located at the maximum distance from the air intake case;
• rather thick walls of the body made of a special material do not come into resonance from the sound, but quench its vibrations
• several V-shaped traps modeled from anti-acoustic material literally absorb all the sounds from the passage of air flow.

Hoods made by the technology of Italian specialists, at minimum speed create noise exposure no more than 30 dB - such sounds do not stand out against the background of general apartment noise, it can be distinguished only at the fourth maximum speed of the fan.

Exhaust performance from the company Falmec reaches 800 m³/ h, while other manufacturers with a much greater noise impact, only from 400 to 600 cubic meters / hour.
