Abstract
Abstract The theory for studying the damping of acoustic waves in metals is evolved in the low temperature region and zero magnetic field starting from primary physical constants and assuming basic potentials. The theory is tested for some highly conducting and transitional metals, viz. aluminium, nickel, copper and lead. It is observed that a sharp change in damping occurs if the temperature is elevated and damping is very high around 10 K. The experimental evidences are found in good agreement with present values. It is concluded that the damping is one of the characteristic properties of metals.
