Abstract :
This paper presents a frequency domain digital hearing aid based upon the new lapped transform, which has the ability to eliminate the blocking effects inherent in traditional frequency domain filtering. Incorporated into the new digital hearing aid are the functions of frequency shaping, acoustic feedback cancellation and periodic noise reduction.
