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.
This allows you to make the cooking process the most comfortable and helpful.
For more complete understanding of the scale of decibels, you can compare
parameters of the following guidelines:
