Railway applications - Acoustics - Measurement of noise inside railbound vehicles

EN ISO 3381-2011 发布历史

"This European Standard specifies the conditions for obtaining reproducible and comparable measurement results of levels and spectra of noise inside all kinds of vehicles on rails or other types of fixed track@ hereinafter conventionally called ""train""@ except for track maintenance vehicles in operation. This standard is applicable for: ?? type testing; ?? periodic monitoring testing. The results may be used@ for example: ?? to characterise the noise inside these vehicles; ?? to compare the internal noise of various vehicles on a particular track section. The test procedures specified in this European Standard are of engineering grade (grade 2@ with a precision of ?? 2 dB)@ that is the preferred one for noise declaration purposes@ as defined in EN ISO 12001. The standard describes tests during different operating conditions@ i.e. driving@ accelerating@ decelerating and standstill. The chosen operating conditions are decided by the relevant authority or the train owner/operator. It is not mandatory to perform tests at all conditions. Infrasound and messages intelligibility are not treated in this standard. The procedures specified for accelerating and decelerating tests are of survey grade."
