Paper Abstract

In dB(A) terms most practical structures (machines, engines, etc.) radiate the major proportion of their noise in the mid frequency range approximately 800 - 2500 Hz. In general, this is due to multimodal vibrations with a relatively high modal order and as such modelling using finite element or modal analysis techniques can be excessively complex. A much simpler, less detailed approach, using energy balance methods (Statistical Energy Analysis, etc.) is much more applicable to this type of vibration.
