In [29], it has been stated that cocktail party effect can be explained by Binaural Masking Level Difference (BMLD).
However, as blind steganographic approach is considered more robust and secure than the nonblind steganography techniques, hence, in this proposed method, "Blind Source Separation" approach has been chosen for solving cocktail party effect.
