Noise has been an issue for airport communities and passengers since the advent of commercial air transport almost a century ago. Impressive gains have been made in aircraft noise control, but expectations are rising and air traffic will at least double in the next 20 years. Also, lighter composite structures pose a challenge for interior noise control. Furthermore, societal expectations for mobility, new technology, demands for carbon footprint minimization, and other environmental imperatives will lead to revolutionary aircraft designs in the future. This tutorial lecture will consider noise from present and future subsonic jet aircraft, rotorcraft, propeller aircraft, and supersonic transports. Noise prediction capabilities will be identified, along with an overview of noise control technology. Acousticians are preparing to predict and control community and interior noise for arbitrary configurations using models based more on first principles, whereas the state-of-the-art is largely semiempirical. It is imperative that acousticians be included in the early stages of the design process and for all design team members to have some exposure to noise control principles to avoid wasting resources on designs that should be nonstarters from the noise perspective.
