pressure - ANSWER-_______ = force per unit area 6, 12, 18 - ANSWER-on a laryngeal source spectrum, showing F0 and harmonics, the F0 is the first and tallest harmonic component -_____ dB/octave is associated with a bright, resonant voice -_____ dB/octave is associated with a typical voice -______ dB/octave is associated with a thin, weak voice aperiodic, nearly periodic - ANSWER-noise is _______ in its waveform, while the human voice is ______ ________ vowels - ANSWER-Pio is equal t...

• what is science?4 features of the scientific method - ANSWER-1) EMPIRICAL - based on data 2) DETERMINISTIC - obeys physical laws 3) PREDICTIVE - if you this....then that will happen 4) PARSIMONIOUS - use the simplest explanation poss. • SLPs' use of technology [why do we use it clinically? how can acoustics help?] - ANSWER-- OVERCOME LISTENER BIAS. Consistent, reliable measurement is provided by analysis. - Use OBJECTIVE TERMS AND MEASURES TO DESCRIBE THE SEVERITY of a disorder obj...

neither invariant nor linear - ANSWER-The speech signal is perceptual normalization - ANSWER-When a listener simplifies the processing of the speech signal to smooth out superfluous variability, it is called categorical perception - 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 - ANSWER-In duplex perception:

what is science? what are the 4 features of the scientific method? - ANSWER--empirical -deterministic -predictive -parsimonious what does it mean for science to be empirical? - ANSWER-based on data what does it mean for science to be deterministic? - ANSWER-obeys physical laws what does it mean for science to be predictive? - ANSWER-if you do this.... then that will happen what does it mean for science to be parsimonious? - ANSWER-uses the simplest explanation possible how many...

In real speech, vowels are seldom produced in ________________. - ANSWER-isolation Usually there are _______________ on either side of a vowel. - ANSWER-consonants The production of the vowel is influenced by the sounds that are: - ANSWER-adjacent to it. What is coarticulation? - ANSWER-When the produciton of a sound is influenced by the sounds adjacent to it. It's quite common for the articulation of one of the corner vowels - /a/ , /i/, /u/, /ae/ to be ____________________, when t...

What is fundamental frequency? - ANSWER-- The lowest frequency of a periodic waveform. - Lowest rate of repetition. - If the waveform has aperiodic components, they could be lower than the fundamental. - A physical measure. Can complex waves still be periodic? - ANSWER-Yes. Simple or complex it does not matter. What does it mean to be "nearly periodic"? - ANSWER-There is a repeating pattern but pattern is not perfect. Minor deviations. Why would SLPs be interested in measureme...

What is fundamental frequency? - ANSWER-lowest periodic frequency, slowest repeating patter or longest wavelength and period. Can complex waves still be periodic? - ANSWER-yes What does it mean to be "nearly periodic"? - ANSWER-There are some minor aperiodicity but there are repeating pattterns What is the period of a sound? - ANSWER-period=1/F0 (the amount of time a single peak to peak cycle takes) What does the Hz unit mean... can you explain it in your own words? - ANSWER-The nu...

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 subglottal pres...

The voice source is basically - ANSWER-the pressure wave generated by the vibrating vocal folds When the air inside a partially or completely enclosed container is set into vibration, we say that the container is a/an - ANSWER-acoustic resonator The characteristic resonances are called - ANSWER-formants The glottal volume velocity is the volume of air flowing through the glottis as a function of - ANSWER-time What is the input energy, raw material if you will, for the acoustic reso...

acoustics - ANSWER-A branch of physics devoted to the study of sound: its production, transmission, and effects. dynamics - ANSWER-The study of the forces that result in the movement of objects. kinematics - ANSWER-The study of motion, the positions, velocities, and acceleration of body parts. _________ is concerned with movements without regard to the forces that cause the movements. psychoacoustics - ANSWER-An interdisciplinary field of psychology and acoustics that addresses the rela...
