Abstract This Standard provides guidance on the compatibility of various human uses of land with the acoustical environment. Thi
7、s Standard uses the annual average of the total day-night adjusted sound exposure or the annual average of the adjusted day-night average sound level to characterize the acoustical environment. The annual average of the total day-night adjusted sound exposure and annual average of the adjusted day-n
8、ight average sound level are explained in Part 4 of ANSI S12.9. An informative annex provides guidance for designation of land uses compatible with existing or predicted annual averages of the total day-night adjusted sound exposure or annual average of the adjusted day-night average sound level. Ra
9、nges of the annual average of the total day-night adjusted sound exposure or annual average of the adjusted day-night average sound level are outlined within which a specific region of compatibility may be drawn. These ranges take into consideration the transmission loss in sound level from outside
10、to inside buildings as commonly constructed in that locality and living habits there.

11、ut license from IHS -,-,- AMERICAN NATIONAL STANDARDS ON ACOUSTICS The Acoustical Society of America (ASA) provides the Secretariat for Accredited Standards Committees S1 on Acoustics, S2 on Mechanical Vibration and Shock, S3 on Bioacoustics, and S12 on Noise. These committees have wide representati
12、on from the technical community (manufacturers, consumers, trade associations, organizations with a general interest, and government representatives). The standards are published by the Acoustical Society of America as American National Standards after approval by their respective Standards Committe
13、es and the American National Standards Institute. These standards are developed and published as a public service to provide standards useful to the public, industry, and consumers, and to Federal, State, and local governments. Each of the Accredited Standards Committees operating in accordance with
14、 procedures approved by American National Standards Institute (ANSI) is responsible for developing, voting upon, and maintaining or revising its own Standards. The ASA Standards Secretariat administers Committee organization and activity and provides liaison between the Accredited Standards Committe
15、es and ANSI. After the Standards have been produced and adopted by the Accredited Standards Committees, and approved as American National Standards by ANSI, the ASA Standards Secretariat arranges for their publication and distribution. An American National Standard implies a consensus of those subst
16、antially concerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessar
17、ily unanimity. Consensus requires that all views and objections be considered and that a concerted effort be made towards their resolution. The use of an American National Standard is completely voluntary. Their existence does not in any respect preclude anyone, whether he or she has approved the St
18、andards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the Standards. NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be
19、taken periodically to reaffirm, revise, or withdraw this Standard.

27、ent of Environmental Sound Part 5: Sound Level Descriptors for Determination of Compatible Land Use. This American National Standard supplements the other five Parts of this series of Standards. Part 1 presents definitions of quantities for description and measurement of outdoor environmental sounds
28、. Part 2 describes methods to measure long-term environmental sounds over wide areas. Part 3 presents methods to measure short-term environmental sound when an observer is present to operate the instruments. Part 4 presents methods to assess noise and predict the long-term community response to nois
29、e. Part 6 presents methods to estimate awakenings associated with aircraft noise events heard in homes. This Part 5 of ANSI S12.9 supersedes and replaces ANSI S12.9-1998/Part 5, which in turn replaced ANSI S12.40-1990 and its predecessor, ANSI S3.23-1980. The revisions contained in this 2007 edition
30、 of ANSI/ASA S12.9 / Part 5 are minor. The most major revision is that the outdoor noise environment recommended by ANSI/ASA S12.9-2007 / Part 5 for schools agrees with the recommendations in ANSI S12.60. Other changes to Figure A.1 are that the marginally compatible zone for single-family homes is
31、reduced by 5 dB to be the same size range as other housing. Largely because of sleep disruption concerns, the un-soundproofed marginally compatible range for health care facilities is reduced to DNL 55 from 60 dB, and the un-soundproofed marginally compatible range for hotels is reduced to DNL 60 fr
32、om 65 dB. The upper limit for health care facilities and hotels that include soundproofing remains unchanged at a DNL of 75 dB. There are numerous editorial changes including the change of the word “noise” to “sound” or “acoustical” and reference to ANSI S12.9 / Part 6. This Standard contains one in
33、formative annex. This Standard was developed under the jurisdiction of Accredited Standards Committee S12, Noise, which has the following scope: Standards, specifications, and terminology in the field of acoustical noise pertaining to methods of measurement, evaluation, and control, including biolog
34、ical safety, tolerance, and comfort, and physical acoustics as related to environmental and occupational noise.

39、 with the outdoor noise environment at a receiver site depends on acoustical and non-acoustical factors. (i) Acoustical factors: the sound level at the receivers outdoor location and its variation with time; the sound isolation provided by the buildings where people experience the effects of outdoor
40、 noise; and the noise environment generated indoors by indoor sources, including sounds produced by people themselves. (ii) Non-acoustical factors: the type of human activity associated with a specific land use; the differing responses of individuals to the same noise environment; attitudes toward t
41、he noise sources and the persons responsible for creating the noise; familiarity with an intruding noise through previous experiences; the disturbance of an activity or the annoyance caused by the noise; specific requirements of individual communities; the cost of achieving lower average sound level
42、s; and the technical feasibility of reducing the sound levels. 0.2 Many rating methods and measurement procedures have been proposed for assessing the compatibility between the noise environment and human activity. To assess the environmental acceptability of a site for various land uses it is desir
43、able, when possible, to use a single measure that applies to sounds from all sources, individually and in combination, contributing to the overall sound at a site. 0.3 This Standard specifies the annual average of the total day-night adjusted sound exposure and corresponding annual average of the ad
44、justed day-night average sound level as the acoustical measures to be used in assessing compatibility between various land uses and an outdoor noise environment. Total day-night adjusted sound exposure and adjusted day-night average sound level are similar to non- adjusted total day-night sound expo
45、sure and day-night average sound level. The difference is that the sound exposures for sounds with special characteristics such as impulsiveness, dominant pure tones, rapid onset, and sounds with strong low-frequency content are adjusted by a factor before they are added into the total. NOTE 1 The a
46、nnual average of the total day-night adjusted sound exposure is the average of the daily total day- night sound exposure over the number of days specifically included in the computation. As such, it can be thought of as the total (day-night) sound (exposure) on the average day. NOTE 2 For some noise
47、 environments, the total day-night sound exposure or the day-night average sound level without some of the adjustments may be more appropriate for assessments of compatible land use. Annex A designates land uses such as sports arenas where the total day-night sound exposure or the day-night average
48、sound level without the adjustments may be more appropriate for assessments of compatible land use. 0.4 Part 4 of ANSI S12.9 describes the calculation of total day-night adjusted sound exposure and adjusted day-night average sound level. Part 1 of ANSI S12.9 defines day-night average sound level and other descriptors of community noise. Part 2 of ANSI S12.9 describes long-term measurement procedures. Part 3 of ANSI S12.9 describes short-term measurement procedures with an observer present. Part 6 of ANSI S12.9 provides methods for the estimation of awak
