本文叙述了1986年9月进行的9台仿真乳突的比对测量。结果表明,测量数据与出厂数据间的力灵敏度偏差均小于±1dB,机械阻抗值均在IEC-373(1983)所给的容限以内,证实了我国骨导听力计量标准装置是稳定可靠的。
This article describes the comparison of nine simulated mastoids performed in September 1986. The results show that the force sensitivity deviation between the measured data and the factory data is less than ± 1dB. The mechanical impedance value is within the tolerance given by IEC-373 (1983), which confirms that the bone conduction hearing measurement standard device in our country is stable and reliable.
