Measure Air Pressure and Flow Flashcards
1
Q
Subglottal Pressure
A
- amount of air needed to open the vocal folds (waterbottle)
- in speech measured in cm h20
- directly related to loudness
1
Q
Phonatory Threshold Pressure
A
- initial pressure needed before speaking
- Conversation: W (300cc); M (500 cc)
- Loud: W (600 cc); M (1000 cc)
2
Q
Twice Tidal Inspiration
A
- taking a turn in a quiet conversation
3
Q
Water Bottle Activity
A
- Subglottal Pressure
- 5:5
- 5 cm h20 = conversational loudness
10 cm h20 = talking loudly
