SECTION 5. Helpful information

Physical characteristics of the sound volume (the sound pressure level) is measured in 

decibels (dB). «Noise» is a chaotic mix of sound.

The human ear can detect sounds with sound volume of 10-15 dB and above.

When choosing a kitchen hood, it is necessary to pay special attention to technical indicators 

such as the noise level. This indicator is very important, because, and that’s beyond a shadow of 

a doubt, each of us spends a lot of time on the kitchen. It is especially common for women who 

love to please their loved ones with delicious cooked dishes.

According to the surveys, 40% of women do not use kitchen hoods for their intended purpose 

(it refers to the process of air suction), precisely because they are annoyed with the noise level.

Consequently, such a necessary and needed in the kitchen appliance, kitchen air cleaner, 

designed to remove airborne odors, grease, soot and smoke, becomes almost meaningless.

For more complete understanding of the scale of decibels, you can compare parameters of 

the following guidelines:
