- This is cross-sectional study a potential relationship between air conduction hearing threshold and blood viscosity in normal adult males(n=1677). We measure hearing threshold in frequency level at 500, 1000, 2000, 4000Hz by pure-tone audiometry and RBC profiles contains red cell number, hemoglobin, hematocrit. Blood viscosity replaced by hematocrit that are one major factor of influencing blood viscosity. PTAs(pure-tone averages) measured by hearing threshold averages level at 500Hz, 1000Hz, 2000Hz by pure-tone audiometry. Grades of PTAs(pure-tone averages) are less then 10.0dB group, between 10.0-19.9dB group and excess 20.0dB. The results are significantly association among hematocrit, red cell number and hearing loss(age adjust by ANACOVA).
