The National Institute of Metrology (Thailand) (NIMT) further strengthened international cooperation in metrology by conducting training in Acoustics and Vibration for the Uzbek National Institute of Metrology (UzNIM) during 26–30 January 2026 at UzNIM, Republic of Uzbekistan.
In the field of Acoustics, Ms. Panisara Kongthavorn delivered an intensive technical training program covering the calibration of sound level meters and sound calibrators, microphone calibration, and the evaluation of anechoic chambers. The training emphasized both acoustic and electrical characteristics, with detailed reviews of UzNIM’s existing calibration procedures, discussions on measurement uncertainty budgets, and alignment with international standards. Particular attention was given to free-field microphone sensitivity calibration using comparison methods, as well as the assessment and measurement systems of UzNIM’s anechoic chamber.
Concurrently, Mr. Pairoj Rattanangkul conducted Vibration Metrology Training, focusing on the transfer of vibration magnitude values from primary to secondary standards. The program addressed primary vibration calibration using laser vibrometers, secondary vibration calibration in accordance with ISO 16063-21, calibration of conditioning amplifiers, and vibration exciter calibration following ISO 16063-44. Comprehensive sessions on uncertainty evaluation, calibration reporting, and traceability statements were also provided, ensuring that participants could confidently apply the methodologies within their laboratories.
This training activity was implemented under the Physikalisch-Technische Bundesanstalt (PTB) project “Supporting the Reform of the National Quality Infrastructure in Uzbekistan”, which aims to enhance Uzbekistan’s national measurement capabilities in line with international best practices.
The successful completion of the Acoustics and Vibration metrology training represents a significant step in advancing UzNIM’s technical competence and laboratory capabilities. It also reaffirms the strong collaborative partnership among NIMT, PTB, and UzNIM, laying a solid foundation for continued cooperation and future joint initiatives in the field of metrology.
