I have been looking in the internet, but I havent found a good response, but I know I am not the best web searcher around, so I will take the shortcut and ask this forum:
I am trying to find the definitions of the A & C weights, found in the RatShack SPL meters and some amps specs (for example, the Outlaw 770 I own specifies S/N of 119dB A-weighted).
Also about noise, I got confused in an article that says that the white and pink noise differs in the freq. spectra that each one carries, but did not specified the freq range or any other thing about it. In one of the papers I read, I kind of understood that pink noise is just between 20Hz-20KHz, and white noise is all over the place. Is that right? is noise just a sum of sine waves in all frequencies or there is something else in noise generators?
If anyone can throw an explanation or a link where I can learn this concepts, I'll appreciate it.
Thanks
