Organization: DIN
Publication Date: 1 November 2014
Status: active
Page Count: 14
ICS Code (Noise emitted by means of transport): 17.140.30
ICS Code (Aircraft and space vehicles in general): 49.020
scope:

This International Standard specifies requirements for instruments and test procedures for the measurement and reporting of sound pressure levels at crew and passenger locations in the interior of aircraft under steady flight conditions. The sound pressure levels may be used to determine various quantities for describing the acoustical environment in the interior of the aircraft. The procedures are intended to ensure uniformity in test results and to provide the basis for determination of measurement uncertainties. 

This International Standard provides electroacoustical performance specifications for a complete measurement system from a microphone to the readout device. Various individual components of a measurement system may be selected so long as the total measurement system conforms to the specifications of this International Standard. 

The preferred measurement procedure involves the recording of sound pressure signals with subsequent analysis into one-third-octave-band sound pressure levels. Direct measurements may be made of one-third-octaveband sound pressure levels.
