Operator-related uncertainty in in-situ airborne sound insulation testing (vor Ort)

Abstract:
Hottinger Brüel & Kjær (HBK) relocated its Copenhagen facility in late 2021. At the same time, development of a new building acoustics measurement system was nearing completion. This presented the opportunity to do a large volume of sound insulation testing with the new system, in an unoccupied facility, and with numerous operators.In addition to usability testing, HBK used this opportunity to investigate operator-related uncertainty of in-situ sound insulation testing. Operators with a wide range of experience levels were selected from across the organization to perform sound insulation testing on a single partition, using the same equipment. Each operator was instructed on the measurement method to follow from ISO 16283-1:2014, but measurement positions were not prescribed.The standard deviation of the measurement results from all participants were then compared to the standard uncertainties for in-situ airborne sound insulation given in ISO 12999-1:2020.
