The phonatory airflow can be measured by means of a hot wire tube placed in the supraglottic space without tying down the tongue. The velocity of airflow above the glottis reaches values around c = 50 to 150 cm/s. The variations in airflow oscillations were recorded. The voice of the person under examination was picked up by a condenser microphone (Bruel & Kjaer No. 2112). According to D'Alembert's wave equation, the sound intensity is related to the velocity of the phonatory air stream. The… CONTINUE READING
