MUIC & ACOUTIC – OUND PHYIC & PYCHOACOUTIC CALCULATOR
Loudness Sone
A precise tool.
What is the Loudness Sone & How does it work?
Loudness, measured in sones, is a subjective measure of sound intensity as perceived by the human ear. It takes into account not just the physical intensity of the sound but also how it is perceived by listeners.
The relationship between loudness in sones and sound pressure level in phons is logarithmic, reflecting the non-linear nature of human hearing. The formula to convert phons to sones is given by:
L_{sone} = 10^{frac{L_{phon}}{10}} cdot 4 cdot 10^{-4}
Lsone = loudness in sones
Lphon = sound pressure level in phons
Lphon = sound pressure level in phons
This formula accounts for the fact that small changes in sound pressure level can lead to large perceived differences in loudness, especially at lower levels.

Frequently Asked Questions
What is loudness in sones?
Loudness in sones is a subjective measure of sound intensity as perceived by the human ear, taking into account both physical intensity and how it’s heard.
How do I convert phons to sones?
Use the formula L_sone = 10^(L_phon/10) * 4 * 10^-4 to convert sound pressure levels from phons to sones.
Why is the conversion between phons and sones logarithmic?
The relationship is logarithmic because human hearing is non-linear, meaning that perceived loudness doesn’t increase linearly with physical intensity.
What does 1 phon equal in sones?
1 phon is equivalent to approximately 0.04 sones when converted using the given formula.
Can this calculator be used for any sound level?
Yes, you can use this calculator for a wide range of sound levels as long as they are provided in phons.
Is there a difference between loudness and intensity?
Yes, loudness is how we perceive sound, while intensity is the physical measurement of sound pressure. They are related but not identical.
How does this calculator help in music production?
It helps in understanding and managing perceived sound levels, which is crucial for balancing tracks and ensuring a good listening experience.
