hello dears

i'm using broad band noise in acoustic , my question is:

how can i compute the _ non tonal- frequency which is mentioned in broadband noise theory from postprocessing in the program or by any equation.

i need this to knew if this frequency annoy to the human ear or not.

regards samar

i'm waiting your response , I use broadband noise 4 acoustic, I compute the over all pressure and over all surface acoustic pressure in db, but how can i know if there are values comfortable to human ear without knowing the frequencies or octave band which relevant to this spl value.

Hey Samar,

I know it is a bit too late ? did you figure out how to calculate the octave band

Thanks
