AIRPORT NOISE. ITS IMPACT AND ALLEVIATION

Present noise alleviation efforts have not yet brought the type of conclusive action which is needed to significantly reduce exposure to high levels of aircraft noise. The inquiry seeks to outline and define in some specifics a systematic approach to resolving the problem of airport noise. Aircraft noise alleviation measures are evaluated by an analytic scheme involving four variables: effectiveness, scope, cost of implementation, and limitations. The three major categories of alleviation measures are studied: insulation of the receiver, separation of the source and receiver, and reductions at the source. The effectiveness of most measures in reducing noise exposure near airports is poor. Zoning is largely unsuccessful in excluding noise sensitive land uses near airports. Acoustic conditioning of structures is too expensive. The analysis did indicate that three methods are potentially capable of significantly reducing noise exposure: retrofitting present engines with acoustically treated nacelles, re-equipping the existing fleet with high-bypass-ratio engines, and noise abatement operation procedures. Additionally, both STOL and VTOL promise reductions in aircraft noise exposure. An examination of mechanisms for coping with environmental problems -- setting standards, subsidies, and taxation or imposition of effluence charges -- showed the latter to be potentially most effective.
