RESONANCE DISORDERS
Hypernasality- coupling of oral & nasal cavities during non nasal (oral) sounds; “ muffled” due to damping effect ( sound absorption) thru turbines.
Hypo nasality: reduced nasal resonance of nasal sounds due to blockage; “ stuffed up”
RESONANCE DISORDERS
Cul-de-sac: structural obstruction; muffled; “potato-in-the mouth”
Mixed: combo on different sounds; common in apraxia
