Acoustics/formulas

So that formulas can be created once and reused, like images, they have been placed into templates.

renders as:

$\eta _{\max }=1-{\frac {2}{k_{\mathrm {eff} }{\sqrt {Q_{E}Q_{m0}}}}}\qquad \left(k_{\mathrm {eff} }{\sqrt {Q_{E}Q_{m0}}}\ll 1\right)$

renders as:

$I_{\mathrm {w} max}={\frac {1}{2}}(\omega _{5}u_{l})_{max}^{2}\ \rho _{m\mathrm {w} }\nu _{\mathrm {w} }(W/m^{2})$

renders as:

$Q_{L}={\frac {1}{k_{eff}}}{\sqrt {\frac {Q_{m0}}{Q_{E}}}}=Q_{Lopt}$

renders as:

$\eta \approx 1-{\frac {1}{1+k_{eff}^{2}Q_{E}Q_{L}}}-{\frac {1}{1+{\frac {Q_{m0}}{Q_{L}}}}}$
