P - Sound pressure, Pa. Pref - reference sound pressure, 0.00002 Pa. As an example, the sound pressure from a . Input Enter either Power Gain (P1/P2) or Voltage gain to calculate the Decibel (dB). So, for example, when buying a range hood that runs at six sones, six is the maximum noise level that the range hood will produce. The ratio may be power, sound pressure, voltage or intensity or several other things. But 2 sounds that have equal intensity do not necessarily have equal loudness. We don't save this data. For loudness above 40 phon or 1 sone. 1 Sone is a sound of an average refrigerator. Loudness level can be expressed in sones or phons, which are both units of loudness. sone to decibel calculator.

As mentioned before, sones are a subjective perception of sound pressure. Sone values are different then decibel measurements because they take into account the frequency and level dependency of human hearing. You can check the specific models with lowest sones here. Doubling the sone value is equivalent to doubling the loudness (i.e. sone to decibel calculator. It is also widely used in electronics, signals and communication. The sone scale attempts to follow human perception for all sound pressure levels so that, for example, doubling the loudness of a sound doubles its value in sone. (This is true for sounds louder than 40 phon. Range hoods typically produce between 3 and 7 sones of sound.
