The authors describe theoretical and experimental 
studies of resonance oscillations of a gas in a tube, with one end 
shut and a periodically vibrating piston mounted on the other. Analytical 
expressions to calculate the amplitude of pressure fluctuations in 
a real gas and experimental results at the frequency of linear resonance 
are obtained. Theory shows good agreement with experiment. An experimental 
study is made of nonlinear resonances of the second and third orders 
and the transition from almost harmonic oscillations of the gas to 
highly nonlinear ones.
