COMD 5070 EXAM 2 STUDY GUIDE Average Air Flow Calculation - Average flow formula: ️ Flow = Air/Time - If 1 liter of air is used and the phonation lasts for 5 seconds, the calculation is: - Average flow = 1 liter / 5 seconds - = 0.2 liters/second (or equivalent to 200 cc/second) - Note: Flow at a given instant may vary, meaning the average flow does not capture transient changes during phonation. --- U-Tube Manometer - How it works: ️ Measures static pressure. - It consi...

COMD 5070 - Exam 2 What is fundamental frequency? - fundamental frequency is a physical measure - it is the speed of vocal fold vibration - correlates to the perceptual correlate of pitch - lowest frequency of a periodic waveform Can complex waves still be periodic? Yes, complex waves can still be periodic. Periodic means that a wave has a repeating pattern. Complex means that there is more than one frequency present. These two things can exist. The wave will have a unique pattern wit...

COMD 5070 Exam 1 Complete Answers The Scientific Method Characteristics: - Empirical: ️ Based on data. - Involves collecting data and interpreting it to understand behavior; making sense of the observed phenomena. - Deterministic: ️ Things obey physical laws. - Indicates that outcomes are not random but follow cause-and-effect relationships, allowing generalizations to be made from data that can be applied to new situations. - Predictive: ️ If a given phenomenon occ...

COMD 5070 Final Exam Guaranteed Success 1. The speech signal is ️ Neither invariant nor linear (This indicates that the speech signal varies significantly across different contexts and conditions.) 2. When a listener simplifies the processing of the speech signal to smooth out superfluous variability, it is called ️ Perceptual normalization (This process helps listeners focus on the essential features of speech despite variability in production.) 3. One type of quanta...

COMD 5070 Exam 3 Complete Solutions the nature of science - the scientific method 1. empirical - based on data 2. deterministic - obeys physical laws 3. predictive - if you do this, then that will happen 4. parsimonious - uses the simplest explanation possible scientific approach involves collecting data so that we can understand the given phenomenon from our own direct experience transverse waves - pebble in a pond - ripples spread outward - wave travels across the surface - obj...

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...

COMD 5070 Exam 1 Study Guide 1. What are the four features of the scientific method? ️ Empirical ️ Deterministic ️ Predictive ️ Parsimonious 2. What does empirical mean? ️ Based on data (This indicates that findings are derived from observation or experiment rather than theory or pure logic.) 3. What does deterministic mean? ️ Obey physical laws (This means that the behavior of the system can be precisely predicted based on initial conditions a...

COMD 5070 Exam 2 Study Guide with Complete Solutions 1. Calculate average air flow A: 1 liters of air used in 10 seconds B: 3 liters of air used in 20 seconds - Answer️️ -Divide Volume by Time flow=air/time Example: If 1 liter of air is used and phonation lasts for 5 seconds Average flow is 1/5 liter per second (keep in mind that flow at a given instant may be different) A: 1/10 B: 3/20 2. U-tube manometer How does it work? What is it best used for? What are its limitations? -...
