Title Acoustics - Determination of sound power levels of noise sources using sound intensity - Part 2: Measurement by scanning
Original title Acoustique - Détermination par intensimétrie des niveaux de puissance acoustique émis par les sources de bruit - Partie 2: Mesurage par balayage [in French]
Bibliographic information International Organization for Standardization, Case postale 56, 1211 Genève 20, Switzerland, 1996. iv, 19p. Illus. 14 ref.
Abstract Part 2 of this international standard specifies a method for measuring the component of sound intensity normal to a measurement surface which is chosen so as to enclose the noise source(s) of which the sound power level is to be determined. Contents: scope; normative references; definitions; general requirements; acoustic environment; instrumentation; installation and operation of the source; measurement of normal sound intensity component levels; calculation of sound power level; information to be reported. Annexes: calculation of field indicators; procedure for achieving a desired grade of accuracy; effects of airflow on measurement of sound intensity; effects of sound absorption within the measurement surface; measurement surface and scanning procedure; bibliography.
