Unit 1
How do you calculate pressure?
Force/Area
True or False: The formants frequencies of a sound change when its pitch changes.
FALSE
What is the function of the vestibular system?
Maintain balance and posture.
Which binaural cue would you use for sounds with longer wavelengths - ITDS or ILDs?
ITDs
What is phase?
Phase is the portion of a cycle through which a waveform has advanced relative to some arbitrary point.
True or false: The speed a sound travels is dependent on the source of vibration.
FALSE
What is the manner of articulation of the sound /p/?
stop
Are binaural localization cues measured on the azimuth plane or the vertical plane?
Azimuth
The filterbank theory states the the basilar membrane acts as a bank of what type of filters?
Band pass filters
The basilar membrane acts as a ___________ when it separates the vibration patterns of complex sounds into their component frequencies.
Fourier Analyzer
What is the name for a short, abrupt noise that is complex and aperiodic?
Transient sound
What are the characteristics of /u/?
A low F1 and F2
What is the name of the area that is the first to receive input from both ears?
Superior olivary complex
What do we use phase for?
Phase is used in determining ITDs and ILDs.
Compare the length of voice onset time for voice and voiceless stops.
Voiced stops have a shorter VOT, and voiceless have a longer VOT.
True or False: In transverse waves, the direction of particle movement is perpendicular to the direction of the wave.
the direction of particle movement is perpendicular to the direction of the wave.
Does a formant frequency become higher or lower when there is a local constriction of the resonating tube near a volume velocity maximum?
It becomes lower.
How is a stimulus presented in order to measure MAF?
In an anechoic chamber, over a loudspeaker
True or false: The reference values for Audiograms are the values presented by the Minimum Audibility Curves and the reference values for minimum audibility curves is 10^12 w/m^2.
TRUE
What are the three structures of the inner ear?
Cochlea, vestibule, semiciruclar canals
True or false: A spectrum shows the change in frequency components over time
FALSE. Spectrogram
What are the three ways the consonant sound /m/ can be classified as?
Voiced bilabial (or labiodental) nasal
Define the minimum audibility curve and the two ways it can be measured.
Minimum absolute thresholds at which we can hear different frequencies; MAP and MAF
In what ways does the vocal tract act as a filter we learned about filters in Unit 1, and we learned about the vocal tract in Unit 2? (Think back to Source-Filter Theory).
The sound is generated by a source of vibration, and it becomes shaped or filtered by the resonant properties of the vocal tract.
True or false: The tongue and the pinna each have differing masses and elasticities that are important for their function, specifically because of how the mass and elasticity affect their vibrations and are related to different frequencies.
False (basilar membrane and vocal folds)
