 The authors introduce and describe an improved model of laryngostroboscope. The main feature upon which this contrivance is operated consists in the simple handling of a pedal, whereby it is possible to select and hold the synchronized light sourse. The main feature of the function of the equipment may be summarized as follows: Automatic synchronization of illumination with vocal vibration; easy connection of several fiberscope on fiver light-guides simultaneously to the light source; photographing by a single flash of any phase of the vocal vibration and videotape recording of the vibrating vocal cord; and, the marking of the phase point in the sound wave pattern on oscilloscope simultaneously with photographing of the vibrating vocal cord.

 In addition to above features it is capable of making observation of th vocal vibration under an ordinary room illumination by adopting a high radiant pulsed xenon flash tube and also read all frequencies by digital indication.
