What is PD CEN/TS 16272-5 - railway sound barrier testing about?
Rail traffic noise is one of the main causes of environmental pollution generated by the railway system. One solution is noise barriers that block the direct path of sound waves from surrounding areas. PD CEN/TS 16272-5 covers technical specifications for the determination of airborne sound insulation under direct sound field conditions in noise barriers, ensuring barrier performance and noise reduction in railway applications.
PD CEN/TS 16272-5 is the fifth part of the acoustic performance test methods multi-series for railway track applications. PD CEN/TS 16272-5 describes a test method for measuring a quantity representative of the intrinsic characteristics of sound reflection from railway noise barriers: the reflection index.
The test method is intended for the following applications:
Determination of the intrinsic characteristics of sound reflection of noise barriers to be installed along railways to be measured either on typical installations alongside railways or on a relevant sample section
Determination of the in situ intrinsic characteristics of sound reflection of noise barriers and claddings in actual use
Comparison of design specifications with actual performance data after the completion of the construction work
Verification of the long-term performance of noise barriers and claddings (with a repeated application of the method)
Results are expressed as a function of frequency, in one-third octave bands bet...
