function noiseId  = getNoiseId(h,r,noise,nRoom,nNoise)
% getNoiseId
% This function associates noise condition index for each {home,room} to a
% global index.
% NOTE : Index "1" always refers the quiet condition
%
% noiseId  = getNoiseId(h,r,noise,nRoom,nNoise)
% 
% INPUTS :
% h : home index
% r : room index
% noise : noise index in home h and room r (between [1,4])
% nRoom : total number of rooms per home (must be 3)
% nNoise : total number of noise condition per room (must be 4)
% nUtt : total number of sentences uttered for each {h,r,spk,pos,noise} 
% (must be 2)
%
% OUTPUT :
% noiseId : Global noise index ("1" for the quiet condition)
