Summary: [Nature Recordists] Re: EIN values and bits and peaks

["John Crockett" naturalcontemplative]

I have also been doing this in Excel. I just posted a small (36KB) spreadsheet 
(calculations.xls) online that does two things:

Calculate microphone EIN (dBu) from any combination of self noise and 
sensitivity.

Calculate total noise for any two combined sources (e.g. microphone + preamp).

I have many other formulas for converting dB to mV/Pa and converting between 
dBV and dBu for example, but these are the two I have been using a lot to 
educate myself about how these parameters interact.

I hope it's useful and saves someone else the trouble!
