Noise control in Space Shuttle Orbiter

摘要

Acoustic limits in habitable space enclosures are required to ensure crew safety, comfort,and habitability. Noise control is implemented to ensure compliance with the acousticrequirements. The purpose of this paper is to describe problems with establishing acousticrequirements and noise control efforts, and to present examples of noise control treatmentsand design applications used in the Space Shuttle Orbiter. Included is the need toimplement the design discipline of acoustics early in the design process, and noise controlthroughout a program to ensure that limits are met. The use of dedicated personnel toprovide expertise and oversight of acoustic requirements and noise control implementationhas shown to be of value in the Space Shuttle Orbiter program. It is concluded that toachieve acceptable and safe noise levels in the crew habitable space, early resolution ofacoustic requirements and implementation of effective noise control efforts is needed.Management support of established acoustic requirements and noise control efforts isessential.
