'Quiet please'
Abstract
The considered investigation has the objective to indicate that noise control is the product of good engineering. It does not depend on learning a whole new discipline nor does it depend on invention. Because of the increasing use of hydraulics and the growth of noise sensitivity in aircraft, it was felt that aircraft hydraulic engineers should be aware of the desirability of noise control. A booklet was written for the general practitioner in aerospace hydraulics engineering. The first principle of quieting is that the most favorable cost-effectiveness ratio is achieved when noise control engineering is part of the original design effort. The second principle of quieting is that the loudest noise component must be reduced before appreciable quieting can be achieved.
