Squared sound pressure on prescribed sub-domain was chosen as an objective functional. The shape gradient function of the problem was derived using the Lagrange multiplier method and the formula of material derivative. Reshaping was accomplished by the traction method. The presented method was applied to a interior noise reduction problem of a car.}, pages = {311--312}, title = {音場を対象とした形状最適化問題の解法(車内音低減問題)}, year = {2000} }
