An expression for the amplitude of the ultrasonic relaxation arising from the exchange of amphiphiles between micelles and surrounding solution has been derived on the basis of the same assumptions as used by Aniansson and Wall to obtain the expression of the relaxation time for this process. The derived expression somewhat extends the range of investigation of micellar systems which can be performed by means of the ultrasonic relaxation method. It has been used for the quantitative interpretation of ultrasonic absorption measurements concerning the effect of ionic strength on the dynamics of the exchange process in micellar solutions of potassium decanoate.
