A method for measuring the frequency-dependent adiabatic bulk modulus of a liquid by measuring the electrical impedance of a spherical piezoelectric shell containing the liquid was presented some time ago. Recent measurements will be reported for several supercooled liquids with temperatures near the glass transition, describing relaxational behaviors of bulk moduli as frequency is varied continuously between 1 Hz and 20 kHz.
