    VOCAL FOLDS FUNCTION MODELLING BY MEANS OF THE PRINCIPLE OF COMPRESSIVE AIR BUBBLE

  • Original language description

    Because of the lack of clarity and numerous weak points found in the principles as defined by different authors in the literature there has been a new principle developed and defined, initially called "compressed air bubble", in short "bubble". Accordingto this principle of the vocal folds function, the main forces acting on the vocal folds during phonation are as follows: ?subglottic pressure under the vocal folds and in the whole trachea; the overpressure acts on the relatively large inner surfaace of the subglottic area, producing a considerable force opening the vocal folds ?resilient forces of the vocal folds muscles which act against the opening of the vocal folds ?inertial forces of the vocal folds; inertial forces of the air bubble cannot playa significant role with regard to the low value of air density, small size of the moved bubble and also to small changes of the airflow speed.

    Modelování funkce hlasivek na základě principu tlakové bubliny

  • Czech description

    V důsledku nejasností mnoha principů o funkci hlasivek prezentovaných v literatuře byl definován nový princip na základě "bubliny tlakového vzduchu". Na základě tohoto principu hlavní síly působící na hlasivky jsou: - subglotický tlak pod hlasivkami - pružné síly hlasivek - setravčné síly struktury hlasivek Setrvačné síly hlasivek nemohou hrát důležitou roli vzhledem k nízké hustotě vzduchu, malé velikosti bubliny a malých změn rychlosti proudícího vzduchu.
