Many efforts have been put in recent years aiming to suppress background noise effectively. Adopting wiener filter is one such method in suppressing background noise by considering both the priori and posteriori signal to noise ratio to calculate the wiener gain. This paper presents Improved Noise Suppression Technique (INST) a new method for background noise suppression. The improved noise suppression technique incorporates both the features of wiener filter based on decision directed approach and two step noise reduction technique (TSNR). Extensive MATLAB simulations, study and analysis of the results shows that Improved Noise Suppression Technique also offers good noise suppression capability.  aDigital Hearing Aid, Wiener filter, Noise suppression, Subband domain signal processing.
