micsens: Microphone sensitivity and conversion

Description

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

Usage

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

Value

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

Details

The sensitivity S in dB is calculated according to: $$S_{dB} = 20 \times log_{10}(\frac{s}{s_{ref}})$$ with s the measured sensitivity in mv/Pa and sref the reference sensitivity (by default 1 mV/Pa).

# conversion of a sensitivity of -54 dB re 1V/Pa
