What is the required procedure for noise level testing at the site?
The noise test readings should be taken in the following process:
For Internal spaces:
• The readings are to be logged in all occupied spaces.
• The instrument should face the windows while taking the reading.
• The readings should be taken between the center of room and 1 meter distance from the window.
For external spaces:
• Readings should be logged between a distance of 1-2 m. of the building envelope and the instrument should face outwards from the building.
Please note that the project team has to submit a third party noise audit report, as part of the compliance document for Criterion No.29. The testing has to be done by a CPCB/SPCB accredited/approved testing agency.
