Transient response of lightly damped rooms: A finite element approach

The finite element method is used to calculate the impulse response of an irregular room. Although only a finite number of degrees of freedom are used, there is sufficient information in the model to predict the early reflections from the walls to a source at any location within the room’s interior. The results of calculations, performed for a room with a curved roof, show how absorption material placed at strategic points on the walls can affect the temporal response.
