 and $\tau$ is the time at which the acoustic information is emitted at the bubble wall. For $t=\tau$ with $r(t)=R(\tau)$, Eq.~(\ref{eq:u_rt_qa}) reduces to $u(R,\tau)=\dot{R}(\tau)$ and Eq.~(\ref{eq:p_rt_qa}) reduces to $p(R,\tau)=p_\mathrm{L}(\tau)$, thus satisfying the boundary conditions at the bubble wall. 
 
-The quasi-acoustic model is consistent in its modelling assumptions with the Keller-Miksis model, Eq.~\eqref{eq:keller}. The applicability of the quasi-acoustic model is limited to small Mach numbers, $(\dot{R}/c_0)^2 \ll 1$, as it incorporates a finite propagation speed of the acoustic emissions and the nonlinear pressure contributions resulting from the flow, but since all parts of the wave propagate with speed $c_0$, the quasi-acoustic model can neither describe the nonlinear distortion of acoustic waves nor the formation of shock fronts.
