Sone values are different then decibel measurements because they take into account the frequency and level dependency of human hearing. Each soundwave, depending on its intensity, changes the atmospheric pressure of the surrounding area. You can use this Sones to decibels calculator to convert any number of Sones to dB. Decibel (dB) Calculator. To achieve this consistency, the sounds are generated for the hearing jury at different combinations of decibels (sound pressure level) and Hertz (frequency). therefore i think a straight conversion is impossible as we dont know the frequency we are dealing with. We don't save this data. Input Enter either Power Gain (P1/P2) or Voltage gain to calculate the Decibel (dB). To calculate that, we just use the Sone to dB formula and repeat the procedure like this: dB (1.5 Sones) = 33.2log10(1.5) + 28 = 33.85 dB. The sone is a unit of volume. Just enter the Decibel value and leave Power Gain & Voltage Gain blank, and then hit the Calculate button. Search: Sone To Decibel Calculator.

This unit provides accurate information on the amount of sound the blower produces inside the vent hood.Sones are measured on a linear scale, like inches or centimeters. The decibel meter uses the sensitivity of the microphone and converts the electrical signal accurately to sound pressure, and shows the resulting level of sound pressure (decibels dB). Eight sones are equivalent to a normal conversation or background noise. Decibel dB Calculator - Definition | dB Levels | Sounds Use fabric hangings or sound-deadening panels on the wall or the back of the door. Keep in mind that all sone values are given with the largest duct available for a given fan. Frequency is a measurement of the total number of sound waves produced in one second. Menu.
