| Abstract: | Noise that accompanies the wave front inversion of sound signals is considered. It is shown that this noise is a consequence of the interference phenomena occurring in complex media with multiple signal reflections, which lead to a noiselike nature of the spectrum modulus. A method of the wave front inversion that allows one to reduce the interference noise is proposed. The aforementioned phenomena are numerically analyzed. |
