Abstract
For a combination of theoretical and phenomenological reasons, it is a rgued that the conventional SEA coupling loss fatter is not the most a ppropriate form of coefficient for relating energy transfer between SE A subsystems to their vibrational states. An alternative `power transf er coefficient' is suggested and an experimental method for its determ ination, which obviates the need to measure input powers, is proposed. (C) 1998 Academic Press.
