4、Calibrators Secretariat Acoustical Society of America Approved 20 September 2006: American National Standards Institute, Inc. Abstract This Standard specifies performance requirements for coupler-type sound calibrators. It replaces ANSI S1.40-1984 American National Standard Specifications for Acoust
5、ical Calibrators, and is technically equivalent (except for the absence of requirements for radio-frequency emissions) to International Standard IEC 60942:2003, ElectroacousticsSound calibrators. The standard specifies performance requirements for the sound pressure level, frequency, and total disto
6、rtion generated by a sound calibrator. It also provides requirements for the influence of environmental conditions, for electromagnetic compatibility, and for instrument marking and documentation. The standard gives details of the tests necessary to verify that a model of sound calibrator conforms t
7、o all the requirements, as well as details of the method for periodic testing of a sound calibrator. The tests require the determination of the actual uncertainties of measurement which are to not exceed the maximum uncertainties allowed for laboratory measurements. AMERICAN NATIONAL STANDARDS ON AC
8、OUSTICS 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 representation from the technical community (manufacturers, consumers,
9、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 Committees and the American National Standards Institute. These sta
10、ndards 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 procedures approved by American National Standards Institu
11、te (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 Committees and ANSI. After the Standards have been produced and ado
12、pted 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 substantially concerned with its scope and provisions. Consensus
13、 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 necessarily unanimity. Consensus requires that all views and object
14、ions 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 Standards or not, from manufacturing, marketing, purchasing,
15、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 taken periodically to reaffirm, revise, or withdraw this St

27、not an integral part of the American National Standard ANSI S1.402006 American National Standard Specifications and Verification Procedures for Sound Calibrators. This Standard comprises a part of a group of definitions, standards, and specifications for use in acoustics. It was developed and approv
28、ed by Accredited Standards Committee S1 Acoustics, under its approved operating procedures. Those procedures have been accredited by the American National Standards Institute (ANSI). The Scope of Accredited Standards Committee S1 is as follows: Standards, specifications, methods of measurement and t
29、est, and terminology in the field of physical acoustics, including architectural acoustics, electroacoustics, sonics and ultrasonics, and underwater sound, but excluding those aspects which pertain to biological safety, tolerances, and comfort.

33、America 2006 All rights reserved 1American National Standard Specifications and Verification Procedures for Sound Calibrators 1 Scope Sound calibrators generate known sound pressure levels at one or more frequencies in a coupler into which a specified model of microphone is inserted in a specified c
34、onfiguration. NOTE An example of a specified configuration may be with or without a grid. This Standard specifies performance requirements and verification procedures for three classes of coupler-type sound calibrators: Class LS: Laboratory Standard calibrator with the smallest tolerance limits. Cla
35、ss 1: Sound calibrators that are generally intended for field use with class 1 sound level meters and similar instruments. Class 2: Sound calibrators that are generally intended for field use with class 2 sound level meters, dosimeters, and similar instruments. For class LS calibrators, the Standard
36、 requires the use of a laboratory standard microphone as specified in ANSI S1.15-1997/Part 1. For class 1 and class 2 calibrators, the Standard requires the use of a working standard microphone as specified in IEC 61094-4:1995. Tolerance limits in this Standard include maximum permitted expanded unc
37、ertainties of measurement as well as the tolerance limits allowed for design and manufacturing. This Standard applies to sound calibrators that are used to check or adjust the sensitivity of sound measuring instruments and systems including conventional, integrating-averaging and integrating sound l
38、evel meters, and personal noise dosimeters. This Standard does not include requirements for the Instruction Manual to provide data for use in adjusting a sound level indicated by a sound level meter, or equivalent instrument, in response to application of a sound calibrator to the equivalent free-fi
39、eld or random-incidence sound level. Sound calibrators may provide two or more sound pressure levels and operate at two or more frequencies. These multiple-level / multiple-frequency calibrators have a single class designation for all combinations of levels and frequencies for which the Instruction
40、Manual states conformance to the requirements of this Standard. Additional useful functions such as tonebursts may be provided. Requirements for these additional functions are not included in this Standard. ANSI S1.40-2006 Acoustical Society of America 2006 All rights reserved 2 2 Normative referenc
