Representatives of the Directorate for Measures and Precious Metals (hereinafter: DMDM) Gordana Stefanović, metrologist for acoustics, roughness and shapes, and Aleksandar Jevremović, metrologist for length in the Department for Length, Optical Quantities and Acoustics, participated in the work of the EURAMET Technical Committee for Acoustics, Ultrasound and Vibration (EURAMET TC-AUV), which was held from 8 to 9 April 2025 in Bern, Switzerland.

The meeting was organized by the Swiss National Metrology Institute METAS. 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 Enver Sadikoglu from the National Metrology Institute of Turkey (UME), who spoke about the organization of 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 Subcommittee on Airborne Sound SC-A (in which DMDM ​​participates), the status of all existing CMCs and the applications for future CMCs from all EURAMET participants were discussed. The TC-AUV Chairman reported that DMDM ​​had successfully maintained the status of the existing CMCs.

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

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

It is proposed that the next EURAMET TC-AUV meeting be held in 2026, hosted by GUM, the National Metrology Institute of Poland, in Warsaw.
