Subjectively, because of the way the human ear works, it's about twice the loudness. With things like bathroom exhaust fans, for example, they have a standardized measurement process (with the same distance between the fan and noise measurement device). This means that doubling the number of sones doubles the noise level. 13 Apr 2006 at 05:43 #3 WJA96 Soldato Joined 13 Jul 2005 Posts 18,627 Location Norfolk, South Scotland In other words, a sound that delivers over four sones is about four times louder than the normal reference level. dBA = 33.2 * LOG10(Sones) + 28 Sones dB Sones dB Sones dB Sones dB Sones dB Sones dB 1.00 28.00 13.00 64.98 25.00 74.41 37.00 80.06 49.00 84.11 61.00 87.27 Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! As a linear measurement, doubling the sone level is equivalent to doubling the loudness; quadrupling the sone value quadruples the loudness, etc. High levels of noise can cause unnecessary stress. Follow this link for an introduction to quantifying loudness. Keep in mind that the calculation is approximate since there is no exact way to calculate decibels from sones. Good luck finding the right vent hood for you! For example: a 10 decibel sound (tone) at 50 Hertz is inaudible to humans, but the same 10 decibel tone at 5000 Hertz is clearly audible.

Enter the values 50 (L2), 100 (d2) and 1.5 (d1) into the calculator and it will calculate L1=86.5dBA. Sone values are generally preferred to phon values because sones are a linear scale. 0000002137 00000 n The calculator below can used to calculate the NC - Noise Criterion: Sound Pressure Level (dB) - Octave band mid-frequency (Hz). 0000215037 00000 n It is very important to understand that sone measurements are subjectivenot objective. Your friends and family can then enjoy the comfort of your kitchen and socialize. As noted above, some prefer to have a loud bathroom fan. Our ears wont even be able to hear such a low sound. This can be seen through the formula above that converts W/m^2 into decibels. The threshold of human hearing, also called the auditory threshold, is widely accepted to be 0 dB. Sound levels are generally expressed in decibels, which are logarithmic and so cannot be manipulated without being converted back to a linear scale. ), you will be better able to know what the machine will sound like. 1 Pa = 1 pascal = 1 N/m 2. Decibel levels use a logarithmic scale like the Richter earthquake scale. Follow this chart instead: Most range hoods have a range hood noise rating of roughly 6 to 10 sones. Make sure it is the right size for the fan. CUSTOM ART FOR CUSTOM NEEDS. The article also provides more details about sones. Decibels are used more often giving you a feel for how loud something is. 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). The perceived loudness of sounds is decided by panels of people with normal hearing. 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. Both sones and decibels are measurements of sound pressure. To convert voltage or power gains to decibels, we can apply the following formulas: N dB = 20log10(AV) = 10log10(AP) N d B = 20 l o g 10 ( A V) = 10 l o g 10 ( A P) Further, the voltage and power gains of the system can be expressed as. For loudness above 40 phon or 1 sone. Example: A bathroom exhaust fan has noise levels of 1 Sone. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); We are reader-supported.
