- •
An acoustic filter is prototyped in parametric loudspeaker using phononic crystals.
- •
A match of transmission loss is obtained between simulation and experimental results.
- •
A frequency dependence from parametric array effect is detected with proposed filter.
- •
The proposed filter has proved to be effective and is only needed for small angles.
