The present paper is reporting numerical and physical experiments in order to increase band width and Transmission loss of a typical Helmholtz Resonator by adding an extra Cavity to the end of the primary cavity. This method has been proved by three ways of experimental, theoretical and simulation. The secondary cavity has its own resonance frequency, thus by optimizing the geometry of the system we can draw both frequencies to a same region. This aggregation of the wave peaks results a considerable increase of both band width and Transmission loss of the modified Helmholtz Resonator.<\div>
