Research of Distortions in the Form Parameters of Audio Broadcasting Signals Using the Method of Complex Statistical Estimation

The analysis of the most significant statistical parameters of broadcast signals has shown that an objective estimation of signal transmission quality in communication channels can be obtained, which has a strong correlation with the subjective estimations of these signals. In the basis of the methodology that allows us to combine objective estimations of the audio signal with the results of subjective-statistical measurements it was proposed to use the complex statistical estimation of the most significant parameters of the signal. An experimental study of the relation between changes in the statistical parameters of the shape of sound signals and the various types of distortions and interference introduced into the signal was carried out. The results of the research showed a high correlation between the changes of the form parameters and their subjective perceptibility.
