Both the velocity of the sound-excited jet flow at a small circular orifice and the nonlinear impedance of the orifice are measured at high sound intensity.

Objective the variations of the site and shape of focal region for a concave spherical ultrasound transducer in the case of high sound intensity and stronger attenuation were studied.

Dynamic pressure Sensors can measure a wide range of varying high intensity sound pressure and high level dynamic pressure events.
