How to convert an FFT Result

Hi!

It's not a question about the FFT functionalities in the Accelerate Framework, more in general.

When I'm doing Fast Fourier Transform I can calculate the db Values from the calculated FFT result.
Correct me please if I'm not wrong. I can calculate the dbV values?
How can I convert this db-Value scale to db SPL,
to build for example a Noise level meter?


kind regards
