A coordinative structure is - answer-a group of muscles that works together to achieve an articulatory goal A formant is most like which type of filter? - answer-band pass A low pass filter - answer-blocks high frequencies A reduced vowel quality applies to - answer-central vowels A simple, low tech tool for a doctor to view a person's larynx is - answer-a laryngeal mirror A single vertical line on a line spectrum would represent - answer-a sine wave An electroglottograph re...

Scientific Method - answer-empirical, deterministic, predictive, parsimonious Empirical - answer-based on data Deterministic - answer-obeys physical laws Predictive - answer-If you do this, then this will happen Parsiminious - answer-uses the simplest explanation possible Why use technology? - answer-overcome listener bias, describe severity objectively, track progress over time, ASHA's focus on evidence-based practice, provide biofeedback to patient How to overcome listener...

1000, 5000, lowest, highest - answer-hearing is more sensitive at some frequencies -lowest thresholds are from _______ to _______ Hz -thresholds are much higher for ______ and for ______ frequency sounds 12, nonlinear, bigger - answer-there are _______ semitones in 1 octave -each semitone is a _________ step- each step upward is _______ than the last (about 5.9%) -no semitones are physically identical in Hz, but they SOUND equal in step size, because our human perception of sound is nonli...

12 - answer-How many semitones are in one octave? 5.9% - answer-There are ________ more semitones in the octave before the last a refinement of everyday thinking - answer-What is science? Acoustic characteristics of burst aspiration - answer-Burst: on flow signal (waveform), shown as a peak with a drastically dropping pressure afterward on spectogram, shown as a black section (with an abrupt start after stop closure) Aspiration: may follow a voiceless stop -only when stop is followe...

A coordinative structure is - answer-a group of muscles that works together to achieve an articulatory goal A formant is most like which type of filter? - answer-band pass A low pass filter - answer-blocks high frequencies A power spectrum is a type of - answer-frequency domain plot A reduced vowel quality applies to - answer-central vowels A simple, low tech tool for a doctor to view a person's larynx is - answer-a laryngeal mirror A single vertical line on a line spectrum ...

_____ is the study of electrical activities in muscles. - answer-electromyography (EMG) ______ ________: single line on a spectrum ______ _______ ________: multiple lines on a spectrum - answer-sine wave, complex periodic signals _______ _________: filtering before digitizing which prevents i.e. using a low pass filter to prevent the higher frequencies from even reaching the digitized system so that they won't contaminate the lower frequency recording by being represented as an a...

A line spectrum is a _______ in time. - answer-snapshot A semitone is always 1/__th of an octave. - answer-1/12th As you lower tongue and jaw, you ______ F1 frequency. - answer-increase As you move tongue backward, (increase/decrease) F2 frequency. - answer-decrease As you move tongue forward, (increase/decrease) F2 frequency. - answer-increase As you raise tongue and jaw, you ______ F1 frequency. - answer-decrease Do we need language competence to perceive phonetic differences...

Can jitter and shimmer co-occur? - answer-yes; you won't find one without the other How do waveforms differ as frequency goes up or down? - answer-higher frequency wavelengths appear closer together with more frequency over a period of time than lower frequencies How does a complex periodic sound change when the fundamental is removed or muted? - answer-when removed, the timbre (quality) differs, but the pitch is perceived as the same How does intensity change with distance? - answer...

4 Features of the scientific method - answer-1. Empirical - based on data 2. Deterministic - obeys physical laws (not random) 3. Predictive - if you do this ... then that will happen 4. Parsimonious - use the simplest explanation possible a low pass filter - answer-blocks high frequencies a simple, low tech tool for a doctor to view a person's larynx is - answer-a laryngeal mirror a single vertical line on a line spectrum would represent - answer-a sine wave amplitude vary in - an...
