The invention relates to measurements. Method is in fact that acoustic pulses are emitted to medium under investigation with registration of time of passage of given distance by those, with determination of sound velocity through it. Registration of time of acoustic pulses passage is performed by instants of change of phase of light wave of focused coherent radiation normal to direction of acoustic radiation.
