The frequency dependence (1-60 MHz) of the ultrasonic attenuation coef
ficient of canola oil, corn oil, olive oil, peanut oil, safflower oil,
soybean oil, and sunflower oil was measured at 25 degrees C. The atte
nuation coefficient of all the oils could be described by the relation
: alpha similar to Af(n) (with A between 6 and 40 x 10(-12), and n bet
ween 1.74 and 1.86).
