The vocal apparatus of the larynx is exceedingly simple, its character being merely that of a membranous reed-instrument, consisting of two elastic plates, stretched so as to leave a narrow fissure between them, so that when the current of air streams through the fissure they are thrown into vibration.

The stronger the current of air, the greater will be the curvature; and the greater the curvature, the greater also the tension which it occasions; a greater tension, however, also produces a higher tone. Thus we find that the pitch of the tone depends upon the strength of the expiratory pressure, whether this pressure is produced from a feeling of pain, or intentionally for the purpose of creating a higher tone.
Página 82 - The most striking example of this inflection of a sonorous wave that I have ever seen, was exhibited at Erith after the tremendous explosion of a powder magazine which occurred there in 1864. The village of Erith was some miles distant from the magazine, but in nearly all cases the windows were shattered ; and it was noticeable that the windows turned away from the origin of the explosion suffered almost as much as those which faced it.
Página 91 - PITCH or height of a tone depends solely upon the rate of vibration ; the greater the number of vibrations in a given time the higher being the pitch.
Página 23 - If they are watched with a laryngoscope during phonation, it is seen that the cords approximate behind so as to narrow the glottis. At the same time they become more tense and their inner edges project more sharply and form a better denned margin to the glottis, and their vibrations, especially in the production of low notes, • can be seen.

Our mental Maw now breaks on the lips into tone and we have the pure vowel with its prefixed consonant, without being aware of the effort that has produced it. The mouth is now closed and if we have not interfered with the focus of attack we hear the initial hum still vibrating pure and beautiful in the facial resonators. IV. After this exercise with the...

The village of Erith was some miles distant from the magazine, but in nearly all cases the windows were shattered ; and it was noticeable that the windows turned away from the origin of the explosion suffered almost as much as those which faced it. Lead sashes were employed in Erith church, and these being in some degree flexible, enabled the windows...
Página 81 - Alpine horn echoed from the rocks of the Wetterhorn or the Jungfrau is in the first instance heard roughly. But by successive reflections the notes are rendered more soft and flute-like, the gradual diminution of intensity giving the impression that the source of sound is retreating further and further into the solitudes of ice and snow.
