The amplitude and intensity of ultrasound waves decrease as they travel through tissue, a phenomenon known as attenuation. Given a fixed propagation distance, attenuation affects high frequency ultrasound waves to a greater degree than lower freq

attenuation [ah-ten″u-a´shun] 1. the act of thinning or weakening. 2. the change in the virulence of a pathogenic microorganism induced by passage through another host species, decreasing its virulence for the native host and increasing it for the new host. This is the basis for the development of live vaccines. 3. the change in a beam of radiation
