    Abstract
    In previous works, baffled-piston with small ratio of piston radius a over the baffle wall aperture radius b, or say, small gap was discussed on subjects mainly focused on acoustics gains. In this thesis, we focus more on baffled-piston models with large gaps and find out what could be the difference these new models may have on the acoustic gains. First we introduce a general description about the original models and further develop it into cavity-backed models with either closed or open end on one side. We use finite difference approximation to evaluate the influential parameters L and lE on acoustic gain. Afterwards calculate and plot curves for gains in related with piston motion frequency f for closed and open cavity models with different configuration parameters with are a/b, b/L and ζ0/b and analyse them and compare with previous works.
