The need of organising a comparison of laboratory standard microphones type LS2aP was agreed during the EUROMET TC AUV “Sound in air” SC and contact persons meeting in Warsaw, held in May 2002. The goal of the comparison is to complement on a regional scale the CIPM CCAUV.A-K3 comparison, in order to be able to demonstrate the equivalence of acoustical pressure standards of European NMIs.. EUROMET TC AUV presented a project N° 674 for the comparison and it was agreed that IEN would be the pilot laboratory. The link to the CCAUV key comparison was realized by the use of BLUE (Best Linear Unbiased Estimator) for the first time in the acoustic metrology field, and the drift of one of the two standards used was taken into account following two different approaches.

Abstract
The need of organising a comparison of laboratory standard microphones type LS2aP was agreed during the EUROMET TC AUV “Sound in air” SC and contact persons meeting in Warsaw, held in May 2002. The goal of the comparison is to complement on a regional scale the CIPM CCAUV.A-K3 comparison, in order to be able to demonstrate the equivalence of acoustical pressure standards of European NMIs.. EUROMET TC AUV presented a project N° 674 for the comparison and it was agreed that IEN would be the pilot laboratory. The link to the CCAUV key comparison was realized by the use of BLUE (Best Linear Unbiased Estimator) for the first time in the acoustic metrology field, and the drift of one of the two standards used was taken into account following two different approaches.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
