Study of the Mean Value of the Non-stationary Acoustic Emission at Reconstruction of Highways

The main statistical characteristics of non-stationary acoustic processes are considered in the given article. The key dependences necessary to estimates the mean value of the acoustic non-stationary emission and the mean values of squares of the non-stationary random radiation process are presented. Particular attention is paid to the correlation functions of the non-stationary random process. The current, local and average statistical characteristics of non-stationary acoustic processes are identified.
