Acoustic Phonetics - answer-Measures of speech production you can get from
microphone recordings and what they can tell us about the way the larynx was
operating and the way the articulators were moving
Aerodynamics - answer-Pressures, flows, and resistances involved in regulating our
breath stream as we speak
Areas of Speech Science Study - answer-1) Acoustic phonetics
2) Physiological phonetics
3) Speech perception
As a general rule, a ___________________ increase in intensity is perceived as twice as
loud. - answer-6-10 dB
Characteristics of Pitch Perception in Music - answer-1) Different octaves are
recognizable because the relationship between the notes is the same anywhere on
the scale
2) Some note pairs, if they are multiples, blend harmoniously
Complex Tone - answer-More than one sign wave--multiple sounds blend together
Complex Tone Characteristics - answer-1) Have many frequencies
2) Fo (fundamental frequency) is often strongest
3) The auditory system responds to all frequencies heard
4) Can be periodic (more pleasant) or not
dB HL - answer-A scale used by audiometers where the physical amplitude is
adjusted so that 0dB reflects the minimum threshold across the entire range of
frequencies generated.
Difference Limens Characteristics - answer-1) Higher frequency sounds must differ
more to be heard as different pitches
2) As intensity increases a larger dB change is needed for us to notice a loudness
difference
3) It's more difficult to tell soft sounds apart if they are fairly close in pitch
Electromyography - answer-Measurement of electrical activity in muscles as they
are activated
Equal Loudness Contours - answer-Show the adjustment needed before certain
lower and higher frequencies can be perceived to be as loud as a 1000 Hz sound.
Greater differences for lower frequency sounds. Adjustment may not be needed for
higher intensity sounds.
Frequency - answer-How often a waveform repeats
