Understanding of speech in noisy environment is great challenge to hearing impaired even with hearing aid. To enhance speech in noisy background various noise reduction algorithms used in digital hearing aid. With noise reduction power consumption and memory optimization considering size is difficult. Selection of algorithms reduces complexity as well as power and memory requirement. This paper take review of basics of hearing aid, challenges faced by hearing impaired and various filters or speech compression techniques used to enhance speech.
