i have a digital storage oscope (school type, owon, etc). i want to use it to capture some sound wave info, specifically to use the data to look at SPL levels of certain types of sounds. the mic i have in mind is a GRAS 40DP.
what would be the best way to do this? i am new to mic's, the spec sheet on the mic says 1mV/Pa. the range i am looking at will be like 0.1Pa(~75db SPL) to 2000Pa(~160 db SPL).
i suspect i need a small opamp to boost the output some so i can get better range on the scope.
your thoughts?
