| ABSTRACT |
|
Recently, many people suffering from voice color change visit otolaryngologist. There is no specific data which can be evaluated objectively for voice color change in korean. In aerodynamic study, maximum phonation time, mean air flow rate, phonatory flow volume and subglottal pressure were tested by using Aerophone II voice function analyzer in korean. 112 male and 122 female aged from 10 to 69 years were randomly selected. Maximum phonation time was 20.8${pm}$6.4sec in male and 17.2${pm}$4.1sec in female. Mean air flow rate was 167.1${pm}$61.4ml/sec. in male and 129.6${pm}$49.3ml/sec in female. Phonatory flow volume was 3184.5${pm}$646.0ml in male and 2122.1${pm}$670.5ml in female. Subglottal pressure was 4.1${pm}$1.8 cmH2O in male and 3.5${pm}$1.4cm $H_2O$ in female. There was no statistically significant difference among age groups in all above results. |
