If the excluded sound is intermittent, the residual soundmay be approximated by the L90. If an excluded sound is steady and there are intermit
32、tent events, the L90 can be used toapproximate the level of such steady sound and the residual sound must be measured with the steady source not operating orapproximated by a measurement at a nearby location where the steady source is not dominant. Though “background noise” bydefinition includes ins

Significance and Use4.1 Evaluation of Environmental NoiseEnvironmental noise is evaluated by comparing a measurement or prediction of thenoise to one or more criteria. There are many
41、 different criteria and ways of measuring and specifying noise, depending on thepurpose of the evaluation.4.2 Selection of CriteriaThis guide assists in selecting the appropriate criteria and measurement method to evaluate noise. Inmaking the selection, the user should consider the following: purpos
42、e of the evaluation (compatibility, activity interference,aesthetics, comfort, annoyance, health effects, hearing damage, etc.); type of data that are available or could be available(A-weighted, octave-band, average level, maximum level, day-night level, calibrated recordings including .wav files fr
43、om whichvarious measurements could be made, etc.); available budget for instrumentation and manpower to obtain that data; and regulatoryor legal requirements for the use of a specific criterion.After selecting a measurement method, the user should consult appropriatereferences for more detailed guid
44、ance.4.3 Objective versus Subjective EvaluationsThe overall sound environment as perceived outdoors is often called asoundscape. Soundscapes have both objective (quantitative) and subjective (qualitative) attributes. This guide is limited to theobjective measurement and evaluation of sound found out
45、doors though the criteria used may be influenced by qualitative factors.Current soundscape research involves evaluation methods and criteria that rely extensively on qualitative factors, both acousticaland non-acoustical, while including requirements for quantitative sound measurement. Two basic ten
46、ets of quantitative soundscapeE1686 163measurements are that the ambient sound at a location is comprised of a combination of specific acoustic events that can bemeasured individually and in combinations; and that the sounds should be measured using methods that represent the ways inwhich they are h
47、eard by people. (1)75. Bases of Criteria5.1 Most criteria for environmental noise are based on the prevention of problems for people. However, there are criteria forevaluating effects on animals, physical damage to structures, or reduced utility of property. When selecting criteria to evaluate asitu
48、ation, it is very important to recognize the many different problems that may be caused by the noise. Sound-scape methodsaddress aesthetic components of sounds and provide for comfortable or satisfying sounds in addition to preventing noiseproblems.(1)5.1.1 Health ImpactsDamage to human hearing is t
49、he best documented effect of noise on health, with the best establishedcriteria. Damage depends on sound levels and exposure time. Most noise-induced hearing loss is due to exposure over severalyears. People are often annoyed by noise at a much lower level than that required to damage hearing. This annoyance causes stressthat can aggravate some physical conditions. Criteria for preventing these problems are usually based on annoyance.
