Abstract

The expression for the high frequency asymptotics of the acoustic noise spectrum induced by collapse of a spherical bubble in viscoelastic liquid (Oldroyd model B) is derived taking into account the liquid compressibility. It is shown that, in the first approximation, the spectral density of the acoustic energy emitted by a cavity collapse varies as the following function of the frequency: S(ω) ∼ ω⁴ exp( - 6αω²) and decreases approximately by 12 decibels per octave in the considered case of dimensionless parameters.
