Abstract

Acoustical nonlinear parameter B/A (adiabatic), (B/A)' (isothermal), sound speed c and density rho measurements in the temperature range of 20 degree C to 37 degree C have been made in excised fat tissues obtained from different parts of the human body. Magnitudes of temperature coefficients of sound speed and difference between adiabatic and isothermal values of B/A correlated highly with water content of the tissue. A reciprocal relationship between B/A and c was observed in soft tissues. In contrast, a linear relationship between B/A and c was observed in protein solutions. No correlation has been found either with B/A or with c with the age of the person from whom the fat tissues were obtained.
