Nonlinear oscillations of a gas in a volume of a cubic resonator at small excitation amplitudes are experimentally investigated. Influence of amplitude and frequency on gas dynamics is studied. It is shown the gas pressure waveform retains a continuous in time for all the being studied amplitudes and excitation frequencies and reaches its maximum at the first eigenfrequency, where it has a weakly expressed nonlinearity.
