PHY03 Sound Attenuation in Solids

Sound Attenuation in Solids Determination of the attenuation of an ultrasonic wave on its way through a medium The attenuation of an ultrasonic wave on its way through a medium is determined by amplitude measurements using the transmission method on bodies of different lengths. Determining the sound attenuation coefficient at different ultrasonic frequencies provides information about the frequency dependence of the sound attenuation. Keywords: Sound attenuation in solids, scattering, absorption, reflection, attenuation coefficient, frequency dependence of sound attenuation, transmission measurement Sound waves lose energy on their way through a medium through various processes such as absorption, scattering or reflection. This loss of energy causes a change in the sound intensity, which decreases with increasing distance. The extent of this attenuation or damping depends on the material. It can be determined by measuring the amplitudes of transmission pulses or reflection pulses in an
