The response of an isothermal solar type atmosphere to adiabatic excitations by various small amplitude acoustic disturbances is studied analytically. Both continuous and pulse excitations are discussed. It is shown that wavetrains of random pulses may be responsible for the excitation of the 3-min solar oscillations.
