出版:International Electrotechnical Committee

專家解讀視頻
Establishes a special frequency weighting characteristic for certain measurements of aircraft noise. Specifies coordinates of poles and zeros of the transfer function in the complex frequency plane as well as the relative frequency response and tolerances. This standard has been prepared for use in conjunction with ISO 3891.
