The amplitudes and shapes of sound pulses generated by laser beams propagating through the atmosphere are numerically investigated. Families of curves are plotted for three different types of the beam time modulation, namely, a triggering pulse, a short laser pulse, and a harmonically modulated radiation. These curves describe acoustic response at an arbitrary distance from the beam axis at any time. Approximate relations for quantitative estimates of the amplitude of sound pulses at various distances from the beam axis are given. They describe the changes in sound pressure with distance to an accuracy of 5%. The frequency dependence of the amplitude of a periodic component of the acoustic signal on the beam axis is also studied.
