If you know what a sone represents in the real world (See chart below. 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. The decibel level of a signal can be expressed as, L = 10 log (S / Sref) (1), S = signal - intensity or power level (signal unit), Sref = reference signal - intensity or power level (signal unit). Our ears wont even be able to hear such a low sound. These curves are equal loudness contours where every sound on each line will have the same perceived loudness. How much is 0.3 Sone in decibels? Loudness, or the strength of a sound, is measured in decibels.

For example, the Broan-NuTone F403004 produces around 1.5 sones. I have been married to the same wife for 46 years. This correlation between sound pressures and sound pressure levels are calculated by Equation 1: L - Sound Pressure Level, dB. Sones are the industry standard noise measurement for fans. Range hoods typically produce between three and seven sones depending on their power, as measured in cubic feet per minute or CFM. As a linear measurement, doubling the sone level is equivalent to doubling the loudness; quadrupling the sone value quadruples the loudness, etc. a decibel is just a logarithmic measurement of power. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); We are reader-supported.

The most common measurement for sound pressure is decibels, but it can also be measured in sones. They developed the Fletcher Munson curves that have been improved upon, but are still in use today. In other words, a sound that delivers over four sones is about four times louder than the normal reference level. Many people want the conversion because decibel ratings are more common and relatable. For pure tones at much higher or lower frequency, loudness in phon will be less than sound pressure level in dB because hearing is less sensitive as you move away from the neighborhood of 1 kHz.
