Decibel To Sone Converter
What are sones and how loud is a sone? Another point of reference that may be helpful is comparing sones to the decibel level of dishwashers.

● between und − Conversion of sone to phon and the problem with and Domain of The subjective perceived sound volume and the artificial term loudness are subjective terms trying to describe the strength of the ear's perception of a sound. The determination of the loudness of stationary signals is defined in ISO 532 or in DIN 45631. The loudness of N = 1 sone is equivalent to 40 phons, which is the loudness level of L N = 40 dB of a sine wave (sinusoid) with a frequency of f = 1000 Hz.
Kurt Tucholsky: 'Noise is the noise of others and one's dog makes no noise.' 'There are many kinds of noise - but only one silence.' Loudness is a personal subjective characteristic of a sound - as opposed to the sound pressure level in decibels, which is objective and directly measurable.

I was researching the 'quietness' of various kitchen range hoods and found this great reference: dBA = 33.2. LOG10(Sones) + 28 It also gives you an idea of subjectively how loud things are. For example, 30 dB = a theater, no talking; 40 dB = residential area at night; 50 dB = quiet restaurant inside; 70 dB = busy traffic at 16 ft.; etc. So the Electrolux island hood I was looking at is rated at 73.8 dB, which makes it pretty noisy in my mind, compared to the Futuro Futuro brand many hoods of which are rated at 0.5 - 3.5 sones (up to about 45 dB. Of course correct installation is everything and I wonder if the Futuro rates theirs including their 'silent kit'.
But at least it's more information that makes it easier to compare. @carossel: you're right, correct installation IS everything. All it takes is one unsealed joint, one run of flexible duct where rigid should have been, one incorrectly aligned mounting bracket, and you've got a range hood that sounds like a Boeing 747 at takeoff. The Futuro sound ratings are for the hoods 'as-is', without the silencer. When they're properly installed, they're very quiet.
You can also use self-adhesive silicone foam sheets to line the chimney cover, that makes it another 10-20% quieter, for only a few bucks more. @Barryv: the reason hoods are rated in sones is because sones are a.subjective.
unit, i.e. This is how loud it will seem.to the human ear., while decibels are a relative unit without any biological reference. Plus, sones are linear, so you can compare 'apples to apples' - 2 sones is exactly twice as loud as 1 sone; meanwhile, with decibels, 60 dB SPL is normal talking volume, 90 dB is a rock concert, and 120 dB = permanent hearing damage. Doesn't seem like a convenient scale to me. That's why sones and decibels don't, strictly speaking, translate.
They measure 2 completely different things. Below this post is a link to an in-depth guide to sones, phons, decibels, and much more.
Converter utilities too, so you can play around with the units. @racmrc: absolutely. I would not recommend any range hood that produces over 6 sones. Doesn't matter what the power or features are - if you can't stand it being turned on, who cares how many CFM it produces? Here is a link that might be useful.
