Abstract
Mechanical impedances of the mastoid portion of the temporal bone and of the forehead were presented for 60 human subjects of both sexes and of ages between 9-71 yr. Measurements were carried out using a plane circular surface of 1.75 cm2 and a static force of 5.4 N (ISO/IEC [International Standards Organization/ International Electrotechnical Commission] conditions). Impedance varied with age and to a lesser extent with sex. Results were consistent with earlier measurements carried out under somewhat different conditions, but deviated rather substantially at most frequencies from the recommended ISO/IEC mechanical impedance for an artificial headbone. A study of the influence of variations in the mechanical headbone impedance upon bone vibrator performance by means of an analogous electrical network was reported.This publication has 1 reference indexed in Scilit:
