[Analysis of statistically homogeneous fragments of acoustic noises generated by insect colonies].
A method of analysis of nonstationary acoustic processes was proposed. The method is based on recurrent integration, which allows tracing the basic tendencies of changes in the time structure of noise being analyzed. The method is applicable for the detection of the statistically homogeneous parts, the comparison of different parts of time series with respect to the correlation function value, and for revealing the internal diagnostic characters in nonstationary acoustic processes of different nature. The method was approved during the investigation of the relations between the changes in the physiological states of bee families and the amplitude-time-frequency structure of acoustic noise generated by them.
