Abstract
A theory is developed to account for the influence of flocculation on the ultrasonic attenuation spectra of emulsions. The theory assumes th at flocculated emulsions contain 'particles' which have effective prop erties determined by the size and volume fraction of the individual dr oplets within the flocs. The theory predicts that the attenuation spec tra of emulsions depends on the size of the droplets, the size of the flocs, the packing of the droplets within the flocs and the fraction o f droplets which are flocculated.
