The temperature-dependent absorption coecient of the fth wave mode is evaluated explicitly near absolute zero temperature by using the temperature-dependent elementary excitation spectrum in bulk liquid helium. The coecient decreases with decreasing temperature, and the main contribution comes from the term including the thermal conductivity.V
