Dynamic vs. Quasi-Static: steady state

• Transients: mechanical properties of the reed play a significant role.
• Steady state: $u_f$ and $\Delta p$ move along a hysteresis loop.

Phase diagram for $u_f(t)$ vs. $\Delta p(t)$ (steady state signals). Mouth pressure $p_0=2267$ Pa, is such that the reed is closing.
The dynamic and the quasi-static models have different attractors.
