abstract = {<p style="text-align: justify;">We study the optimal design problem of acoustic liner to
minimize fan noise radiation from commercial aircraft engine nacelles.
Specifically we treat the liner impedance factor as a parameter and seek
to estimate its optimal value that minimizes far-field radiated noise.
The existence of such an optimal parameter is proved under the
assumption that the Helmholtz equation governs the noise field. We also
present numerical results to demonstrate that the choice of the optimal
liner impedance factor does result in significant reduction of noise
level in the far-field.</p>},
