Abstract :
This paper provides a new solution to the problems faced during the calibration and testing of the type 1 acoustic calibrators. The requirements, resulting from the analysis of those problems, are formulated, and a multichannel automatic measurement system, satisfying those requirements, is presented in details. The system is designed for investigation, aging and correction of digital acoustic calibrators. The results of testing exemplary calibrators obtained by means of the developed system are presented and discussed. According to our knowledge, such a solution has not yet been up to now developed and applied in the production and testing of acoustic calibrators.
