% load_noisePos
% This function loads noise position
%
% [label,noisePos] = load_noisePos(corpusPath,h,r,noise,nRoom,nNoise)
%
% INPUTS :
% corpusPath : path to the corpus
% 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)
%
% OUTPUT :
% label : text label
% noisePos : 1x3 vector : noise position
