Sound transmission

This research has raised the question of whether the vibration transmission at a wall junction depends on how the wall is excited (by either a sound wave or a mechanical shaker). The aim of this research is to investigate this question and hence contribute to the revision of the series of standards. Villot and Guigou-Carter (2000) have considered this problem but their equations (10) and (13) appear to be in error. This research will endeavour to derive the correct equations and r epeat Villot and Guigou Carter’s calculations.

The aim of this research was to develop a method for predicting the level of sound radiated from a finite flat panel or finite opening in any particular direction relative to the level of sound radiated in the direction normal to the finite flat panel or finite opening.
