Abstract:
The vocal pathology is very frequent among the teaching professionals. We have selected 140 teachers, 70 normals, and 70 with dysphonia. To all of them we have realised a complete voice exploration: aerodyinamic tests, tone and extension of the voice, perceptual evaluation of the voice with the GRBAS scale and also a videolaringostroboscopy to diagnose the teachers. Among the dysphonic teachers there is a poor neumophonologic coordination, a major use or an inadequate use of the respiratory and/or laryngeal musculature. The dysphonic teachers present a more pathological voice in the GRBAS scale than the normal teachers.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

Auditory Perception
Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
