Web12.2.4. Attenuation Attenuation of ultrasonic waves in a medium is due to: • specular reflections • divergence • scattering from inhomogeneities • thermal absorption: is the most significant source of attenuation in diagnostic ultrasound p(x,t)=Pcos(ωt−kx) Monochromatic plane wave equation p(x,t)= Pe−αxcos(ωt−kx) with attenuation WebAttenuation is a general term that refers to any reduction in the strength of a signal . Attenuation occurs with any type of signal, whether digital or analog . Sometimes called loss , attenuation is a natural consequence of signal transmission over long distances. The extent of attenuation is usually expressed in units called decibels (dBs).
