What reading level is A Manual of School Hygiene; Written for the Guidance of Teachers in Day-Schools book?
To quickly assess the difficulty of the text, read a short excerpt:
In this state the air passes to and fro without sound. By the exertion of muscles the chords can be tightened and the chink between them narrowed. Then if the air is expired with more or less force its passage causes a vibration which gives rise to the voice. The sound varies in loudness according to the force of the expiration and the note varies from low to high (in the same individual) according as the chords are loosely or tightly drawn. The mechanism so far is comparable to an THE AIR PASS...AGES 159 harp. When the sounds are modified by movements of the tongue, teeth, and lips articulate speech is accomplished.
The only points needing attention from teachers are, that the higher the note the greater the muscular exertion, and that the quality of the voice that is to say its clearness, huskiness etc. Is affected by the healthy or unhealthy con- dition of the whole mucous tract lining the nose, throat etc. And not only by the state of the larynx.
The voice is not directly harmed by school work.
