Subglottal pressure - Study guides, Class notes & Summaries

COMD 5070 exam 2 study guide 1. What is another name for volume velocity? ️ Air flow (This term refers to the amount of air moving through a given area in a specific time period.) 2. How do you calculate the average air flow (volume velocity)? ️ Volume/time (Air flow is typically expressed in cubic centimeters per second (cc/s) or liters per minute (L/min).) 3. What is a u-tube manometer? ️ A tube in the shape of a 'U' that is used to measure pressure and can be...

calculate average air flow - ANSWER-flow=air/time • if 1 liter of air is used... • and phonation lasts for 5 seconds... • average flow = 1/5 liter per second • or 200 cc/second or 0.2 liters/second • flow at a given instant may be different u-tube manometer: how does it work? - ANSWER-Measures static pressure Tube in the shape of a u water in tube is identical until water in the tube/pressure applied displace water measure the difference in height= amount of centim...

4 features of the scientific method - ANSWER-Empirical: based on data Deterministic: Obeys physical laws, things are not random Predictive Parsimonious: Use simplest explanation but no simpler How many semitones in an octave? - ANSWER-12 What is the Nyquist frequency? - ANSWER-Half the sample rate The highest frequency the recording is able to reproduce High pass filter - ANSWER-Allows high frequencies through Low pass filter - ANSWER-Allows low frequencies through Band pass f...

What is another name for volume velocity - ANSWER-Air flow How do you calculate the average air flow (volume velocity) - ANSWER-volume/time What is a u-tube manometer - ANSWER-A tube in the shape of a 'U' that is used to measure pressure and can be used to calibrate electronic equipment to measure pressure. How does a u-tube manometer work? - ANSWER-Pressure will displace the water and the displacement can then be measured by measuring the difference in height What is a u-tube mano...

perceptual - ANSWERwhat we hear acoustic - ANSWERwhat we can measure 4 characteristics of voice production: pitch - ANSWERperceptual: how high or low a persons voice is acoustic: the measurement of the number of a person's vocal folds vibrate per second (fundamental frequency) fundamental frequencies of men, women, and children - ANSWERmen: 125 Hz women: 225-250 Hz children: 400 Hz 4 characteristics of voice production: intensity - ANSWERperceptual: "loudness" how loud or how s...

Which of the following formants typically characterizes a high vowel? A.High-frequency second formant (F2) B.High-frequency first formant (F1) C.Low-frequency first formant (F1) D.Low-frequency second formant (F2) - C.Low-frequency first formant (F1) The F1 is inversely associated with tongue height, such that high vowels tend to have low F1 frequencies. A large metropolitan school district wants to determine the prevalence of developmental stuttering among all enrolled students duri...

The study guide for EXAM #2 in Comd 5070 provides detailed answers to key concepts related to voice production and airflow measurements. It covers topics such as volume velocity (air flow), u-tube manometers for pressure measurement, subglottal pressure, phonation threshold pressure, and the dynamics of vocal fold oscillation. The guide also discusses the relationship between pressure, flow, and resistance in speech production, as well as the physiological aspects of vocal register changes. Vari...

What are the direct measures of subglottal pressure? - ANSWER tracheal puncture, esophageal pressure/balloon -make a hole in the trachea below the larynx and put a pressure transducer in the trachea -not for the faint of heart

SLP PRAXIS - VOICE DISORDERS QUESTIONS AND ANSWERS RATED A+ In which breathing pattern is thoracic enlargement achieved by expansion of the lower thoracic and abdominal cavities during inspiration? Diaphragmatic-abdominal breathing The maximum volume of air that can be exhaled after a maximum inhalation is: Vital capacity Men have a vital capacity in the range of: In the range of 4L to 5L What is the function of the visceral and parietal pleura? To prevent the lungs from collapsing What is ...
