Attenuation of Multilocal Resonant Coupled Cylindrical-shaped Sonic Crystal with Various Slit Position and Axis Orientation Angle

Attenuation and frequency response of coupled tubular-shaped sonic crystal with various slit position and axis orientation angle has been analyzed through an experimental approach. The test specimens model is constructed by two cylindrical-shaped resonators with different diameter d1 and d2. Both resonators coupled in a certain configuration with inter-axis distance (d1
