Apparatus to determine the complex mass of a viscous fluid contained in a rigid porous solid from acoustic pressure measurements.
Two experimental techniques to determine the frequency-dependent complex mass of a viscous fluid contained in a rigid porous solid are investigated. In one technique the moving mass of the fluid is by its effect on the measured input electrical impedance of a moving coil transducer. In the second te...
