A method for acoustic stimulation of the respiratory system is described. The goal of the method is to increase the vital capacity of the lungs. The method is based on the interaction between an acoustic wave synchronized with breathing and the human respiratory system. The acoustic wave frequency scan is performed within a range determined by measuring the frequency-sensitive absorption coefficient of the respiratory system. The scan range is selected at a level of −3 dB relative to the maximum value of the coefficient of absorption of acoustic oscillations.
