To illustrate this even further, lets calculate how many dB is 3 Sones equal to: dB (3 Sones) = 33.2log10(3) + 28 = 43.84 dB. The sound power in decibel from a source with the highest possible to hear sound power can be calculated as L = 10 log ((100 W) / (10-12 W)) = 140 dB Example - Sound Power from a Fan A fan creates 1 W of sound power. When you want to cook lower-heat food, you can go with one of the quiet settings. Perceived loudness is a psycho-acoustic quantity that depends on sound pressure level, the frequency spectrum, and the time behavior of the sound in question. In terms of power it's ten times the power. What is a sone and how does it apply to vent hoods? One sone is similar to a whisper or the sound of an extremely quiet refrigerator or dishwasher. At 1.5 sones, it is the quietest and most affordable . Consistent exposure to 85 dB and above may result in hearing damage or hearing loss. The lower limit of the human hearing threshold is frequency dependent producing different sone hearing values at different frequencies. In some ways sone noise levels are easier to understand then decibel levels. If you select a range hood with a large motor and multi-speed setting, you can strike the right balance. One sone is arbitrarily set equal to the loudness of a 1,000-hertztone at a sound level of 40 decibels above the standard reference level (i.e., the minimum audible threshold).

Decibels, however, are a bit hard to imagine. Sone measurements are a linear table, meaning that a doubling of perceived sound represents a doubling of the sone value. As you can see, most new range hoods and bath fans are fairly quiet. Sone values are generally preferred to phon values because sones are a linear scale. Although the sone is a measure of perceived sound, and cannot be measured with a meter or gauge, engineers and designers continue to use it as a reference. Our decibel calculator level meter can measure sound levels up to 140 dB. The engineers who designed the table below included fairly wide sone ranges. 9).

The original research into how the ear hears different frequencies at different levels was conducted by Harvey Fletcher and Wilden Munson in 1933. To achieve this consistency, the sounds are generated for the hearing jury at different combinations of decibels (sound pressure level) and Hertz (frequency). This app uses your smartphone's microphone to detect sound and display it in decibels as well as display the last 30 seconds of data on an easy-to-read graph. If the 1 KHZ frequency is varied, it becomes necessary to re-calibrate the phons and sone numbers. Heres the calculator: You can try this example: Check how many dB is 0.5 Sones. The sound intensity level in dB is determined . As the sone to decibel calculator shows, 3 sones is 44 decibels. Sones vs. Decibels It is about as loud as a face to face conversation using a normal indoor voice. According to the sone scale, a 1 sone sound is defined as a sound whose loudness is equal to 40 phons. This is abbreviated to dB, and is a logarithmic scale. 0000002567 00000 n The human ear can safely endure levels of less than 80 dBA. Sone values are different then decibel measurements because they take into account the frequency and level dependency of human hearing. When installing a vent hood in your home, youll probably want a quieter hood. You can use this same procedure to convert Sones to dB for any number of Sones. This means that sones are not always measured the same way because it is dependent on the perceptions of the people doing the measurements. 0000018478 00000 n A sone, named by Stanley Smith Stevens in 1936, is an internationally recognized unit of measurement for loudness. Each time the volume is increased by 10 phons (10 decibels at 1 KHz), the sone volume will double, as the following chart from Wikipedia Sone demonstrates. Aircraft takeoff, trains, and quite loudly concerts would fall to the 110+ decibel level. Tightening these items will limit vibration noises like rattling or knocking.
