An attempt was made to study the ultrasonic attenuation in Cu-Zn, Ag-Cd, Ag-Mg and Ag-Zn alloys, due to phonon-phonon interaction at 300 K. The Morse potential was used to evaluate the second and third order elastic constants. How far the neighbouring atoms are effective and contributing to ultrasonic attenuation was studied. It is concluded that most of the ultrasonic attenuation is covered by the atoms from 1st to 8th shell. The contribution to ultrasonic attenuation due to 9th shell to 12th shell is very small. It is also concluded that alloys behave more or less in the same manner as metals.
