FIELD: acoustics.

SUBSTANCE: invention relates to acoustics, in particular to devices for reproducing low-frequency sound waves. Infrasound generator comprises a hollow body with an inlet annular channel on one of its walls for supplying compressed gas, and with an opening on the opposite wall of the body, in which a modulator is installed in the form of a cylindrical tube coaxially with the annular channel, one end of which is located opposite the annular channel and has an internal chamfer. Larger diameter of the chamfer is equal to the larger diameter of the annular channel. Inlet annular channel is formed by the pipe and the insert that is installed inside it and has a cylindrical surface, forming an annular channel, and a conical surface facing away from the annular channel, and a partition with through channels is installed inside the pipe from the inlet side.
