Abstract
Acoustic analysis of voice sometimes requires a constant mouth to microphone distance. In this study a miniature head mount condenser microphone was compared to a larger, professional grade condenser microphone typically mounted on a stand. Long term and short term amplitude and frequency perturbation measures of human phonation were made for comparison. The results indicate that for this type of analysis only small differences exist between the two microphones. This suggests that errors associated with variable source to microphone distance can be reduced without losing baseline quality in transducing voice signals for analysis.
