- •
Schlieren imaging has been used for visualizing ultrasound.
- •
It is difficult to be applied to the audible sound field.
- •
Spatio-temporal filter bank is proposed for enhancing the visibility.
- •
The proposed method enables audible sound field visualization.
- •
The simulation and experiment verified its effectiveness.
