With conventional methods the sound velocity c in fluids can be determined using the back wall echo. This paper proposes a novel technique, in which the signals reflected by scattering particles suspended in a fluid are analysed instead. The basic idea is that the particles generate the strongest echo signal when being located in the sound field maximum. Therefore the position of the echo signal maximum...
In ultrasonics, the time of flight to the object interfaces is often the only information that is considered. From this information, one can either determine distances or sound velocities if the other value is known. A combined determination of the sound velocity and the distance of the scattering particles to the transducer makes it possible to measure sound velocity profiles. To determine distance...
