National Standard TCVN 10615-3:2014 (ISO 3382-3:2012) on Acoustics – Measurement of room acoustic parameters – Part 3: Open plan offices

1. Scope

This standard specifies methods for measuring room acoustic properties in open-plan offices, including office furniture and equipment. It outlines measurement procedures, required equipment, scope of measurements, data evaluation methods, and test report presentation.

The measurement results can be used to evaluate room acoustic properties in open-plan offices. This standard applies to medium and large open-plan offices.
