Microphone sensitivity and conversion

This function converts microphone sensitivity from mV/Pa to dB.

micsens(x, sref = 1, inverse = FALSE)

`x`	a measured sensitivity in mV/Pa (or in dB if `inverse` is `TRUE`)
`sref`	the sensitivity reference (by default equals to 1 V/Pa)
`inverse`	logical, if `TRUE`, the inverse conversion from dB to mV/Pa is computed.

The sensitivity S in dB is calculated according to:

S = 20*log(s/sref)

with s the measured sensitivity in mv/Pa and sref the reference sensitivity (by default 1 mV/Pa).

A numeric value in dB re 1V/Pa with default settings, in mV/Pa if inverse is set to FALSE.

# conversion of a sensitivity of 2 mV/Pa
micsens(2)
# conversion of a sensitivity of -54 dB re 1V/Pa
micsens(-54,inverse=TRUE)
