The equivalent resistance, capacitance and the Q factor of a quartz crystal vibrating at its fundamental frequency in several gaseous media were measured and the results compared with the acoustic impedance (P C ) of the media. While the resistance varies linearly with P C the reciprocal capacitance does not. The Q factor seems to vary linearly with viscosity within the small range of viscosities.
