Although well\u2010equipped clinics gain most ENT requirements for investigation from the video endoscope, the nature of stroboscopy prevents the investigation over single glottal periods and many transitory problems may be missed. A high\u2010quality Lx signal waveform will reflect any irregularities in mucosal contact and substantially complements the endoscopy examination. Yield, however, is a problem in the environment of an ENT hospital voice clinic. In this topic paper the criterion of maximum acceptable normalised noise energy (NNE) = \u221215 dB is used to assess the quality of 61 Laryngograph measurements. By this criterion a pass rate of 78% was achieved. This is considered to be good within an ENT voice clinic population where voice problems are in fact the dominant reason for referral.<\/jats:p><jats:p>Le laryngographe portatif fournit au niveau de la glotte un graphique non acoustique du contact humide de la muqueuse lors du cycle vibratoire des cordes vocales; dans la terminologie du laryngographe ce graphique s'appelle la courbe Lx.

W\u00e4hrend gut ausgestattete Kliniken die meisten HNO\u2010Untersuchungsbed\u00fcrfnisse mit dem Video\u2010Endoskop erf\u00fcllen, verhindert das Prinzip der Stroboskopie die Untersuchung einzelner Perioden und viele transitorische Probleme k\u00f6nnen \u00fcbersehen werden. Ein gutes Lx\u2010Signal spiegelt Irregularit\u00e4ten des Schleimhautkontaktes wider und erg\u00e4nzt im wesentlicher Hinsicht die endoskopische Untersuchung. Der Ertrag ist jedoch ein Problem in Bereich der HNO Stimmkliniken. F\u00fcr diesen Beitrag wurde das Kriterium der maximalen akzeptablen H\u00f6he normalisierter Rauschenergie (normalised noise energy, NNE) = \u221215 dB angenommen, um die Qualit\u00e4t von 61 laryngographischen Messungen zu bewerten.
