Research has found that human-caused noise can detract from the quality of the visitor experience in national parks and related
areas. Moreover, impacts to the visitor experience can be managed by formulating indicators and standards of quality as suggested
in park and outdoor recreation management frameworks, such as Visitor Experience and Resource Protection (VERP), as developed
by the U.S. National Park Service. The research reported in this article supports the formulation of indicators and standards
of quality for human-caused noise at Muir Woods National Monument, California. Phase I identified potential indicators of
quality for the soundscape of Muir Woods. A visitor “listening exercise” was conducted, where respondents identified natural
and human-caused sounds heard in the park and rated the degree to which each sound was “pleasing” or “annoying.” Certain visitor-caused
sounds such as groups talking were heard by most respondents and were rated as annoying, suggesting that these sounds may
be a good indicator of quality. Loud groups were heard by few people but were rated as highly annoying, whereas wind and water
were heard by most visitors and were rated as highly pleasing. Phase II measured standards of quality for visitor-caused noise.
Visitors were presented with a series of 30-second audio clips representing increasing amounts of visitor-caused sound in
the park. Respondents were asked to rate the acceptability of each audio clip on a survey. Findings suggest a threshold at
which visitor-caused sound is judged to be unacceptable, and is therefore considered as noise. A parallel program of sound
monitoring in the park found that current levels of visitor-caused sound sometimes violate this threshold. Study findings
provide an empirical basis to help formulate noise-related indicators and standards of quality in parks and related areas. 相似文献

目前,冷却塔噪声评价所采用的指标是A声级。而由于A声级并不能全面的反应冷却塔噪声污染的特性。本文通过对冷却塔噪声污染案例进行频谱监测,探讨了频谱分析方法对评价冷却塔噪声污染特性的可行性。 相似文献
