4、titute, Inc.AbstractThis Standard specifies mechanical dimensions and certain electroacoustical characteristics for capacitor(condenser) microphones used as laboratory standards for sound pressure measurements of the highestattainable accuracy. The specifications are intended to ensure that primary
5、calibration by the reciprocitymethod can be readily carried out. This Standard establishes a system to classify laboratory standardmicrophones into a number of types according to their dimensions and properties. This American NationalStandard is comparable to International Standard IEC 61094-1:1992,
6、 Measurement microphones Part 1: Specifications for laboratory standard microphones.ANSI S1.15-1997 Part 1AMERICAN NATIONAL STANDARDS ON ACOUSTICSThe Acoustical Society of America (ASA) provides the Secretariat for AccreditedStandards Committees S1 on Acoustics, S2 on Mechanical Vibration and Shock,
7、S3 on Bioacoustics, and S12 on Noise. These committees have wide represen-tation from the technical community (manufacturers, consumers, and general-interest representatives). The standards are published by the Acoustical Society ofAmerica through the American Institute of Physics as American Nation
8、al Stan-dards after approval by their respective standards committees and the AmericanNational Standards Institute.These standards are developed and published as a public service to providestandards useful to the public, industry, and consumers, and to Federal, State,and local governments.Each of th
9、e Accredited Standards Committees operating in accordance with pro-cedures approved by American National Standards Institute (ANSI) is responsiblefor developing, voting upon, and maintaining or revising its own standards. TheASA Standards Secretariat administers committee organization and activity a
10、ndprovides liaison between the Accredited Standards Committees and ANSI. Afterthe standards have been produced and adopted by the Accredited StandardsCommittees, and approved as American National Standards by ANSI, the ASAStandards Secretariat arranges for their publication and distribution.An Ameri
11、can National Standard implies a consensus of those substantially con-cerned with its scope and provisions. Consensus is established when, in thejudgment of the ANSI Board of Standards Review, substantial agreement hasbeen reached by directly and materially affected interests. Substantial agreementme
12、ans much more than a simple majority, but not necessarily unanimity. Consen-sus requires that all views and objections be considered and that a concertedeffort be made towards their resolution.The use of American National Standards is completely voluntary. Their existencedoes not in any respect prec
13、lude anyone, whether he or she has approved thestandards 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 anytime. The procedures of the American Nation
14、al Standards Institute require thataction be taken periodically to reaffirm, revise, or withdraw this Standard.Standards SecretariatAcoustical Society of America120 Wall Street, 32nd FloorNew York, New York 10005-3993Telephone: 11 212 248 0373Telefax: 11 212 248 0146E-mail: asastdsaip.org 1998 by th
