A considerable number of 'field indicators' or 'quality indicators' have been proposed in connection with sound power determination based on measurement of sound intensity. The purpose of this investigation has been to examine these quantities. The conclusion is that some of the quantities are of obvious utility because they have simple relations to certain errors. However, other quantities have been found to be more vaguely related to measurement accuracy, and still others have no obvious physical meaning.
