Ultrasound attenuation spectroscopy

Ultrasound attenuation spectroscopy is a method for characterizing properties of fluids and dispersed particles. There is alternative term for this method: acoustic spectroscopy

There is International Standard on this method. It is described in details, including theory with experimental verification and multiple applications by Dukhin and Goetz.

Measurement of attenuation coefficient versus ultrasound frequency yields raw data for further calculation of various system properties.


 * Most often use of these raw data is calculation of the particle size distribution in heterogeneous systems like emulsions, colloids.


 * In the case of acoustic rheometer these raw data is being converted into extensional viscosity or volume viscosity.

Instrument that employes ultrasound attenuation spectroscopy is reffered to as Acoustic spectrometer
