[Clinical application of intermediate spectrum analysis of the voice. Preliminary study].
Until now, the objective examination of the voice quality has remained confined to the laboratory. The coming out of the Brüel and Kjaer 2033 type high-resolution voice frequency analyzer led us now to realize a rapid recording and easy reading of the fundamental frequency and of the main harmonics. An objective document can thus be filed as a comparison before and after treatment. The recording relates to the intensity in terms of the frequency. The intensity is principally investigated in the linear mode, that is, in mv. The frequency is usually recorded from 0 to 1000 Hz so that one can observe the first harmonics. The retained tests in addition to the intensity and the frequency peaks are the peak enlargement, the hooks and the parasite vocal sounds.
