It was smaller than the Acoustic Wave Music System and used two 2.5-inch speakers. [ 3] A "Wave Radio/CD" model was introduced in 1998 and was essentially a Wave Radio I with a CD player.
Perceptual Objective Listening Quality Analysis ( POLQA) was the working title of an ITU-T standard that covers a model to predict speech quality by means of analyzing digital speech signals. [ 1] The model was standardized as Recommendation ITU-T P.863 (Perceptual objective listening quality assessment) in 2011.
