The study also presents a process that could be used to modify or develop noise control regulations that would be designed to achieve specific national park objectives. The report summarizes the current noise laws and regulations of the National Park Service, presents summaries of some relevant state and local noise laws, and reviews Society of Automotive Engineers (SAE) noise measurement standards that are frequently used to quantify the noise of vehicles that might be encountered in parks, namely motorboats, snowmobiles and motorcycles. The report then discusses a process for noise regulation development that is designed to produce laws that are (1) feasible (can be complied with), (2) effective (will produce the desired limitations of noise), and (3) workable (can be enforced). 收起
