MOORE1997 - Loudness model for stationary signals

Usage

[results] = moore1997(inSig,fs);

Input parameters

insig input signal
fs sampling frequency [Hz]

Output parameters

results structure containing the excitation pattern

Description

Optional parameters:

'fs',fs model-internal sampling frequency [Hz]; it is strongly recommended to use the default of 32 kHz
'flow',flow lowest frequency at which to evaluate the outer/middle ear transfer function
'fhigh',fhigh highest frequency at which to evaluate the outer/middle ear transfer function
'order',order order of the FIR filter used for deriving the outer/middle ear transfer function
'erbStep',erbStep spacing between successive excitation patterns [cam]
'erbFcMin',erbFcMin lowest center frequency [Hz] at which to calculate the excitation pattern
'erbFcMax',erbFcMax highest center frequency [Hz] at which to calculate the excitation pattern

This code calculates the excitation patterns as in moore1997 and the specific loudness.

Examples:

fs = 32000;
t = linspace(0,1,fs);
sig = sin(2*pi*1000*t).';
inSig = scaletodbspl(sig,100);
