Right, Oryoki, of course.

1/ Go for the db(A) figures
2/ make sure that the output of the mic overrides the noise of the input
preamp.

These simple rules can be used by all naturesound recordists.
If you want to put your mic into a base drum, or blow the trumpet into it,=

or  even put it into a grand piano - then you enter another field.
