The instrument described here is designed for calibration of osteal telephones in the frequency range from 0.1 to 15 kHz. In contrast with foreign units of similar intention, the "artificial mastoid" has the impedance of its operating surface sufficiently adequate to the mean mechanical impedance of the parotid region and the forehead of the man within the whole range of operating frequencies. The instrument permits audiometry in extended frequency range in cases of osteal sound conductivity.
这里所描述的仪器是为校准频率范围在0.1至15千赫的骨导助听器而设计的。与国外类似用途的装置不同，“人工乳突”在其整个工作频率范围内，其工作表面的阻抗与人体腮腺区域和前额的平均机械阻抗充分匹配。该仪器可在骨导听力传导的情况下，在扩展的频率范围内进行听力测定。
