Hi there,

I'm a computer programmer and I'm building an application for a company who
manufactures hearing aids.

They use different gain calculation methods such as NAL,
BERGER,POGO,1/2,2/3,1/3.
According to these methods, some frequencies are said to be interpolated,
like 750 hz and 6Khz.
I've looked into Lagrange's and the Aitken-Neville techniques.

What algorithm or method is used for the interpolation ?
Are there any other known methods to calculate gain ?
Where on the NET can I find more info on technical issues regarding hearing
aids ?

Thanks
