(State-By-State Chart), How To Convert Therms To kWh? In 1936 Stanley Smith Stevens proposed the sone as a measurement of noise. 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 We have our answer: 1.5 Sones is equal to 33.85 dB. They tend to be more powerful and typically emit between 3.0 and 7.0 sones. Since decibels are a measure of the difference of sound pressures, a reference sound pressure must be given. Start with the mounting nut holding the blade to the motor assembly. Energy quantity x is field quantity y (amplitude rms) squared: x ~ y2. To achieve this consistency, the sounds are generated for the hearing jury at different combinations of decibels (sound pressure level) and Hertz (frequency). To convert phons to sones, use this formula: Sones = 2(phon-40)/10. Cookies are only used in the browser to improve user experience. We may or may not be compensated for purchased you make as a result of our recommendation.
