micsens

Microphone sensitivity and conversion

Description

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

Usage

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

Arguments

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.

Details

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).

Value

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