[edit] Sones at 0 dB

Can someone explain how dBs relate to Sones below 40 dB? If an increase of 10 DB is a doubling of Sones, then 30 dB should be .5 Sones, 20 dB should be .25 Sones, 10 dB should be .125 Sones and 0 dB should be .0625 Sones. However the chart says the threshold of sound is 0 Sones, which is understandable if a Sone is a "perceived" sound level -- if you don't hear anything, it would be 0 Sones. If this is the case, how do the numbers map to Sones between 0 dB and 40 dB? How is the perceived level measured or calculated? -- ☑ SamuelWantman 09:06, 9 February 2008 (UTC)

That's an excellent point. There's nothing wrong with your calculations, but I think the introduction is slightly misleading. There is no citation that I can see for the mapping of a factor 2 in sones to a 10 dB change in sound level, but my guess is that this mapping breaks down for very low levels of sound, close to the hearing threshold.

I think the part missing from the article is a description of where the sones value comes from. The single number comes from a summation of the sound pressures in each of the frequency bands, and is effected by things like prominent tones that are significantly louder than other sounds in the spectrum, or two prominent tones close to each other, or other spectral situations. Also, which method of calculation was used? Whereas overall sound pressure is a logarithmic summation of numbers (with or without weighting), loudness is much more complicated, and you can't try to equate or correlate dB's with sones. That said, I'm not editing the entry because I don't know what to say. (I know just enough to be dangerous...) --Freqdomain (talk) 14:07, 3 June 2008 (UTC)

[edit] auditory threshold

auditory threshold at 2 kHz ==> isn't it at 1kHz ?????? —Preceding unsigned comment added by 78.113.58.88 (talk) 16:37, 8 May 2008 (UTC)

[edit] Lack of References

I found the base page to be very informative, but from other interactions with Wikipedia, I was surprised to find no references for the data provided. When I came to the discussion page, I find out its part of a wikipedia project. Shouldn't that data be documented on the base page in addition to the discussion page? Charles W.
