A review is presented of the effectsinfluencing the ionosphere which are caused by acoustic emission from differentsources (chemical and nuclear explosions, bolides, meteorites, earthquakes,volcanic eruptions, hurricanes, launches of spacecrafts and flights ofsupersonic jets). A terse statement is given of the basic theoretical principlesand simplified theoretical models underlying the physics of propagation ofinfrasonic pulses and gravity waves in the upper atmosphere. The observations of"quick" response by the ionosphere are pointed out. The problem ofmagnetic disturbances and magnetohydrodynamic (MHD) wave generation in theionosphere is investigated. In particular, the supersonic propagation ofionospheric disturbances, and the conversion of the acoustic energy into theso-called gyrotropic waves in the ionospheric E-layer are considered
