Document Summary
Vocal fold vibration. subglottal should be higher than supraglottal. Vocal fold vibration is a lateral and vertical movement. Bernouli effect at a point of constriction, velocity increases and pressure decreases. Vocal fold vibration subglottal air pressure air going from bottom to top, from high to low pressure, Vocal attack process of brining vf together to being phonation, stimulate muscle. Medial compression force when vf come/ hit together adduction. Fundamental frequency is higher for females (200hz) than for males (120hz), children (300hz) are higher than adults. Fundamental frequency changes with age because of differences in mass and length of vocal folds. vocal intensity in phonation. Pressed (harsh) = increase in strident (harsh quality), more damage, medial compression. Breathy = air wasted louder, closed phase will be longer. Changing pitch = mass per unit decreases, length of vf (f0) increases, tension increases. Changing loudness = increase subglottal pressure or increasing medial compression. Frequency number of cycles of vibration per second.
