Attenuation and speed of ultrasound in lung: dependence upon frequency and inflation

Attenuation and speed of ultrasound in lung: dependence upon frequency and inflation

F Dunn. J Acoust Soc Am. 1986 Oct.

Abstract

The dependence of the speed of sound and the attenuation coefficient upon exposure frequency, in the range of 1-5 MHz, and upon level of inflation, in the range of mass density 0.35-0.7 g/cm3, are reported. The speed of sound decreases linearly and the attenuation coefficient increases exponentially, for all levels of inflation studied.
