The contributions of these authors allow a critical comparison of the varied experiences in developing and applying the different diagnostic methodologies employed in several parts of the world.

In order to increase the accuracy of vibration analysis decision making, other measurement parameters must be used. This paper will present some of the lesser used techniques by way of machinery case histories.
