Representatives of the Directorate for Measures and Precious Metals (hereinafter: DMDM), Slobodan Zelenika, Head of the Department for Length, Optical Sizes and Acoustics, Gordana Stefanović, metrologist for acoustics, roughness and shapes and Aleksandar Jevremović, metrologist for length, participated in the work of the EURAMET Technical Committee for Acoustics, Ultrasound and Vibration (EURAMET TC-AUV), which was held hybridly, from April 14 to 15, 2026, in Warsaw, Poland.

The organizer of the meeting was the National Metrological Institute of Poland (GUM). The EURAMET TC-AUV meeting was attended by more than 25 participants, representatives of National Metrology Institutes (NMI) and Designated Institutes (DI) from most European countries.

The chairman of this meeting was Dominique Rodríguez from the National Metrological Institute of France (LNE), who spoke about the organization of the EURAMET TC-AUV, which is divided into three subcommittees:

• Sound in the air SC-A;
• Ultrasound and underwater acoustics SC-U;
• Acceleration and vibration of the SC-V.

At the meeting of the Airborne Sound Subcommittee of SC-A (in which DMDM ​​participates) the status of all existing CMCs and the application of future CMCs of all EURAMET participants were discussed. The Chairman of TC-AUV announced that DMDM ​​successfully maintained the status of existing CMCs.

Serbia is one of the countries currently participating in the EURAMET.AUV.A-K6 key comparison for LS2P (half-inch laboratory etalon microphones - gold standards) with 14 other European countries, including Saudi Arabia.

The work of the EURAMET TC-AUV is important for areas such as industry, healthcare and environmental protection. The goals of these meetings are continuous monitoring of relevant topics in the field of metrology in acoustics, improvement of communication and cooperation within EURAMET, as well as exchange of ideas and plans for future activities.

The next EURAMET TC-AUV meeting is proposed to be held in 2027, organized by CEM, the National Metrological Institute of Spain, in Madrid (Tres Cantos).
