Tracebility of Acoustical Etalons

Acoustical metrology has to follow the growing field of numerous very differnet technical applications of sound. In our country we also consider the possibilities of establishing national etalons for sound pressure in air, water and solids. For this purpose the most accurate measurement methods must be selected and uncertainities of calibration procedures must be determined in accordance with internationl standards. The tracebility of acoustical etalons to international etalons should be established by absolute calibrations, supported by interlaboratory comparison. Users'calibrators and measurement transducers should be treated as working standards and should be calibrated to the best possible accuracy.
