This work addresses the problem of evaluating noise reduction techniques for hand-free telecommunications. It summarizes objective quality measures that are used in such a context. Finding a high correlation between objective and subjective tests remains a key point. In this paper, we propose a composite measure that appears more correlated with listening tests than classical ones. Its parameters are first determined by a training period and then this measure is validated using different noise cancelling approaches.
