Representatives of the Directorate for Measures and Precious Metals (DMDM), Gordana Stefanović, a metrologist for acoustics, roughness and shapes, and Aleksandar Jevremović, a contracted individual working in the Dimensional, Optical, and Acoustic Department, participated in the EURAMET Technical Committee for Acoustics, Ultrasound and Vibration (EURAMET TC-AUV) meeting from May 16th to 17th, 2023.

The meeting took place in Vienna and was organized by the Austrian National Metrology Institute (BEV). More than 25 representatives from national metrology institutes (NMI) attended the meeting.

The chairperson of this meeting was Enver Sadikoglu from the Turkish National Metrology Institute (UME), who spoke about the organization of TC-AUV, which is divided into three subcommittees:

• Sound in Air SC-A
• Ultrasound and Underwater Acoustics SC-U
• Acceleration and Vibration SC-V

During the EURAMET TC-AUV meeting, the EURAMET 2030 strategy was presented, which involves the development and maintenance of measurement infrastructure in Europe in line with the needs of society and industry and providing support to member countries.

The Subcommittee on Sound in Air SC-A discussed the status of existing Calibration and Measurement Capabilities (CMCs) for Acoustics Laboratory at DMDM and the submission of future CMCs by all EURAMET participants. The chairperson of TC-AUV announced that DMDM successfully maintained the status of existing CMCs.

It was proposed for DMDM to participate in the CCAUV.AUV.A-K6 for LS2P (half-inch laboratory standard microphones - gold standards) with participants from seven other countries, as well as to organize a trilateral comparison between UME, GUM, and DMDM for LS1P (one-inch laboratory standard microphones - gold standards) in which DMDM would be the convenor.

The work of EURAMET TC-AUV is important for industries such as industry, healthcare, and environmental protection. The objectives of these meetings are to continuously monitor relevant topics in the field of acoustics metrology, improve communication and collaboration within EURAMET, and exchange ideas and plans for future activities.

It was proposed that the next EURAMET TC-AUV meeting be held in 2024, organized by the National Institute of Ireland, in Dublin.
