The current status of acoustical metrology in Turkey

Acoustical measurements play an important role in many aspects of our daily life. In order to ensure the validity of performed measurements and to provide the necessary technical basis for decision-making, the traceability to national and international standards has to be established. The milestone for the process is the well defined hierarchy of standards developed in the specific country starting from the national standards based on the definition of SI units and ending at the calibration of instruments used in on-site measurements. This hierarchy includes primary realization of standards used in acoustical metrology and their dissemination directly by the calibration of instrumentation at national metrology institutes or indirectly through a calibration services provided by secondary level laboratories. This paper describes the current status of acoustical metrology in Turkey and outlines plans for future developments.
