8、S12.14-1992 (ASA 101-1992) AMERICAN NATIONAL STANDARD Methods for the Field Measurement of the Sound Output of Audible Public Warning Devices Installed at Fixed Locations Outdoors ABSTRACT This American National Standard describes relatively simple procedures for measur- ing and reporting certain pr
9、operties of sounds produced by audible public warning devices. Methods are given for the measurement of the C-weighted sound level and for determining the one-third octave band containing the fundamental frequency of tonal warning sounds produced by audible public warning devices at a distance of 1
10、O0 ft (30.5 m) from the device and at the mounted height of the device. A method is also given for measuring the maximum level of the sound from a warning sound source at the heads of bystanders on the ground. These methods may be used by manufacturers to specify, in part, the sound produced by thei
11、r products, by custom- ers to verify compliance with pertinent sound output specifications, and by warning system designers to estimate warning sound coverage.

13、hanical Shock and Vibration, S3 on Bio- acoustics, and S12 on Noise. These committees have wide representation from the technical community (manufacturers, consumers, and general-interest representa- tives). The standards are published by the Acoustical Society of America through the American Instit
14、ute of Physics as American National Standards after approval by their respective standards committees and the American National Standards Institute. These standards are developed and published as a public service to provide stan- dards useful to the public, industry, and consumers, and to Federal, S
15、tate, and local governments. This standard was approved by the American National Standards Institute as ANSI S12.14-1992 on 12 March 1992. An American National Standard implies a consensus of those substantially concerned with its scope and provisions. An American National Standard is intended as a
16、guide to aid the manufacturer, the consumer, and the general public. The existence of an American National Standard does not in any respect preclude anyone, whether he has approved the standard or not, from manufacturing, market- ing, purchasing, or using products, processes, or procedures not confo
17、rming to the standard. Ameri- can National Standards are subject to periodic review and users are cautioned to obtain the latest editions. Cation Notice: An American National Standard may be revised or withdrawn at any time. The proce- dures of the American National Standards Institute require that
18、action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication. The American National Standards Institute, Inc. (ANSI) is the national coordinator of voluntary standards development and the clearing house in the U.S. for information on national a
19、nd international standards. The Acoustical Society of America (ASA) is an organization of scientists and engineers formed in 1929 to increase and diffuse the knowledge of acoustics and to promote its practical applications.
