Question

14.5 sones is equal to how many decibels?

Answer 1

78.58dB

Answer 2

1 sone is 40 decibels (1 kilohertz)

A sound is of x sones if the listener describes it as x times louder than 1 sone.

The phon is also a unit of subjective sound loudness, but the phon is more closely related to the decibel. A sound of 20 decibels will be about 20 phon depending on how it is perceived.

You can convert between phon and sone. If you estimate that decibel and phon are the same you can convert between decibel and sone.

a sound of x sones = 10 log[sub]2[/sub] x + 40 phons

a sound of x phons has loudness 2[sup](x - 40)/10[/sup] sones

Answer 3

@trsram: not quite... if you don't believe me, check the internet. Here's one reference which says:
dBA 40 50 55 60 65 70 75 80 85 90
sones 1 2 3 4 6 8 11 16 22 32
so no way 14.5 sone is 580dB!!!
