COMD 5070 final prepAs sound travels through air, it does so as a - correct answer longitudinal pressure wave The period of a sine wave - correct answer is shorter for higher frequency sounds Pressure can de defined as - correct answer force divided by area Intensity can be defined as - correct answer power per unit area The inverse square law means that - correct answer intensity decreases by a factor equal to the square of the change in distance Based on the equal loudness curve...

COMD 5070 Fundamental FrequencyWhat is fundamental frequency? - correct answer *The lowest frequency *Reflects the rate at which the vocal folds are vibrating *Lowest rate of repetition; assumes there is repetition *Highest amplitude harmonic component of all the individual waves that add up together to make the voice spectrum Pitch is what kind of characteristic? - correct answer Perceptual not acoustic What is pitch influenced by? - correct answer *spectral properties of a sound *bala...

COMD 5070 quiz questions study guide finalOne reason why the study of speech production addresses the subsystems separately, and in sequential order, is - correct answer this approach simplifies a large and complex topic Evidence to support the view that acoustic targets are the main control variables for speech comes from - correct answer distortions in the speech of people with hearing impairment What is one of the theoretical problems associated with the idea of motor programs? - correc...

COMD 5070 - Final Examwhat is science? what are the 4 features of the scientific method? - correct answer -empirical -deterministic -predictive -parsimonious what does it mean for science to be empirical? - correct answer based on data what does it mean for science to be deterministic? - correct answer obeys physical laws what does it mean for science to be predictive? - correct answer if you do this.... then that will happen what does it mean for science to be parsimonious? - cor...

ComD 5070 exam 1 Acoustic Analysis What 4 things must you nave to get good data (IOW - a good recording)? - correct answer 1) QUIET recording ENVIRONMENT (reduce reverberation) 2) QUALITY MICROPHONE 3) GOOD SIGNAL STRENGTH (so info won't get lost in "noise") saturation, not clipping 4) PROPER SAMPLE RATE (err on the side of detail) What does REVERBERATION mean? - correct answer - ECHOING (from hard surfaces) What does SATURATION refer to? - correct answer - SIGNAL LEVEL as it come...

COMD 5070 Final Examneither invariant nor linear - correct answer The speech signal is perceptual normalization - correct answer When a listener simplifies the processing of the speech signal to smooth out superfluous variability, it is called categorical perception - correct answer One type of quantal perception that occurs as we listen to speech is called syllable components are presented separately, but simultaneously, to each ear - correct answer In duplex perception: the place a...

USU COMD 5070 - Exam 1The Scientific Method 1. empirical 2. deterministic 3. predictive 4. parsimonious Empirical -based on interpret data, direct experience to make sense of behavior -opp. to rational approach in philosophy based on reasoning/careful thought Deterministic -obey physical laws of cause/effect, not random Predictive -if do this, that will happen, can extrapolate to other situations not experienced yet Parsimonious -uses simplest explanation possible

COMD 5070: Exam 1: Week 4 (Digital Systems) What is Digital Sound? MP3 vs. Tapes/Vinyl Music on mp3 players vs. tapes or vinyl records: "it's different", "it's clearer", "it's more convenient", "it's better" What is Digital Sound? Can your ears hear digits? It's not the sound itself that is digital – sound is still perceived as air vibrations, but the way the sound is stored is digital, stored in numeric form. However, the sound is played in analog form. ...

COMD 5070 exam 14 features of the scientific method - correct answer 1) Science is empirical- we collect data and interpret it (based on data) 2) Science is Deterministic - Things are not random. Because of cause and effect, we can draw generalizations from the data that we have and extrapolate 3) Science is predictive - if you do this, then that will happen. 4) Science is parsimonious - use the simplest explanation possible, try to describe things in economical terms so we can understand it....
