The frequency- and concentration-dependent absorption coefficients of longitudinal and transverse ultrasonic waves in pure and α-alanine-doped triglycine sulfate (α-TGS) crystals (α-alanine content in crystals is: 5, 10, 15, 20, 25, 30, and 35 mol%) grown from solution at room temperature were studied. It is established that absorption coefficients of ultrasonic waves in α-TGS crystals with L and S polarization with the increase in concentration of α-alanine about 1.57 and 1.88 times decrease, and propagation velocity increases by 3.24 and 13.38%, respectively. Decrease of absorption coefficients of transverse ultrasonic waves caused by elastic scattering of phonons on impurity, i.e., decrease of τ, at the corresponding dispersive properties of a phonon subsystem.
