Problems of metrological assurence of acoustic ear impedancemeters

Acoustic bulletin, Vol. 2 4, (1999) p.49-57
The problems of metrological assurence of modern audiology instruments for objective investigation of human hearing function, namely, the acoustic ear impedancemeters, is considered. Mentioned equipment belongs to the measurement instruments for medical assignings, to wich the state metrological supervision is spreaded. The hierarchy scheme of separate channels of the impedancemeter are presented, which are expedient for using at the development of the technique of verification of the middle ear analyzers that would be uniform for national legal metrology services.
