N10 sones sound calculation

Hello everyone,

I am working on a project that relates to finding the N10 value (top 10% of the loudness in sones) from a generated sound file (.WAV) I found a useful free toolbox online "Loudness Toolbox" that is capable of generating N5 in phons. After some modification with the calculation, I was able to calculate N10 in sones but it is no where near my expected data. Can anyone point me to the right direction for doing the N10 calculation? Either another toolbox or point out the mistake I made?

Thanks a bunch! Regards, Bruce

Hi Bryce, Sorry I am a little late in a reply haha but you would want to calculate time varying loudness with this: https://www.mathworks.com/help//audio/ref/acousticloudness.html

Then calculate the statical 90th percentile for N10. Acousticians like to do that the opposite of statisticians haha. Hope this helps you or someone else.
