Measurement Uncertainty in Airborne Sound Insulation and Single-Number Quantities: Strategy and Implementation in Indian Scenario

A Retrospective View of Noise Pollution Control Policy in India:Status, Proposed Revisions and Control Measures

“…The detailed explanation and basis of choosing these values can be found in Garg et al 14 . The choice between the sound insulation criterion down to 50 Hz or the common lower limit of 100 Hz may be exercised 22 depending upon the calibration and measurement capabilities (CMCs) of testing laboratories engaged in sound transmission loss testing in India 23,24 . Thus, in the Indian context, clear-cut guidelines for sound regulation requirements like those in European member states shall not only provide a harmonization of sound descriptors with those followed in other countries, but shall also be helpful in reducing the R&D costs for the building industry in India for development of suitable products or systems with desired noise level reductions 25 .…”
