NeuLoud (Calculates Loudness Level) 1.0

Calculates Loudness Level according to ISO-226:2003 using Artificial Neural Networks for any SPL.Hi. This function is an update of work of:VdoTsctor Espinoza, Rodolfo Venegas, Sergio Floody"Modelo de Sonoridad Utilizando Redes Neuronales" (Loudness Model using Neural Networks)V Congreso Iberoamericano de AcdoDostica FIA 2006Santiago, Chile, 25-28 Octubre 2006L=NeuLoud(f,NPS)f : frecuency [Hz]NPS : Sound Pressure Level [dB]L : Loudness Level [Fon]This script is free for academic use of the source is quotedIt prohibits commercial use of this functionThanks to Rodolfo Venegas by the original version of scripthttp://rodolfo.venegas.googlepages.com/ Contact:VdoTsctor Espinozavespinozac@gmail.comhttps://sites.google.com/site/acusticavec/ Install Copy "NeuLoud.m" and "RedLoud.mat" to a new directory (NeuLoud2011, for example), and add folder with menu File-Set Path-add folder, select NeuLoud2011 folder, click save, close the "Set path window", and check install using function in Matlab command window. Optionally, i have attached an object "CFIT", of the isophonic curve "0 fon" in the file RedLoud.mat to avoid values outside the range of the function NeuLoud as IS0-226: 2003 To find the SPL of the curve "0 fon" useSPL_0_fon = zero (f); where f is the frequency in Hertz In Matlab must be installed the toolboxes Neural Network and Curve Fitting.
