In this chapter, a conceptual framework for noise reduction is proposed. This new formulation gives a better insight into this fundamental problem. Within this framework, we define all important performance measures and criteria that will be of great help in the derivation of the most well-known estimators. Some key discussions concern also the definitions of speech intelligibility and speech quality that will be used in the rest of this work.
