Follow this link for an introduction to quantifying loudness. Browse our quiet range hoods at the banner below, which have a max sone level of just 4.5. If the decibel value and reference level are known the absolute signal level can be calculated by transforming (1) to, S = Sref 10(L / 10) (2), S - signal- intensity or power level (signal unit), Sref - reference signal - intensity or power level (signal unit). Range Hood CFM for Electric vs. Gas Cooktops. As you can see, most new range hoods and bath fans are fairly quiet. First, you can convert your fans sones rating to decibels. Youve landed in the right place! This is roughly the appropriate range of sound level for your range hood. I have also been writing semi-professionally for about 20 years--construction articles, personal stories, and politically incorrect social commentary. Sound level (dB) decreases as the distance from the sound source increases so any measurement of sound level is meaningless unless you specify the distance at which the measurement was taken. This will stop knocking sounds. But some electrical or mechanical equipment like range hoods and bathroom fans give sound value in sones. Just enter the Decibel value and leave Power Gain & Voltage Gain blank, and then hit the Calculate button. We explain to them that Sones are a unit of loudness and they can be converted to decibels. Please see Room Loudness Sones Reference Chart at engineersedge.com. Definition and examples. External blowers are separate from the hood entirely, installed outside your home to drastically reduce the sound level. A sone is defined as a unit of sound or loudness.
