Chapter 4 Flashcards
What are three parts to the communication model?
Source
Message
Reciever
Disruption of any parts of this model creates failure in:
Speech perception
Fundamental frequency of male is _ than females
Lower
For children, FF is _ than adults
Higher
FF depends on the length of the _ _
Propagation velocity
The propagation velocity depends on the _ and _ of the vocal folds
Mass and tension
The speaker’s pitch is associated with the _ frequency of the glottal harmonic series
Lowest
The VT modifies the glottal wave, enhancing those frequencies that correspond to the vocal tract’s natural resonant frequencies and damping those that do not. This is referring to:
Frequency response curve
The frequencies at which the VT will resonate the most are illustrated by the _ of the FRC
Peaks
This peaks are called:
Formants
What is a shouting level in dB SPL?
85 dB
Comfortable level in dB SPL?
65 dB
Faint speech?
45dB
The vowel has about _ times as much energy as the weakest phoneme
680
There is greater power/acoustic energy for _ than consonants
Vowels
Vowels are _ than consonants
Longer
With vowels, air flows through the mouth with no _
Obstruction
With consonants, air flow is:
Partially or completely obstructed
What is coarticulation?
Articulation and perception of sounds are influenced by the sounds around it
Distinguish detection from discrimination from identification:
Detection is hearing the sound
Discrimination is discriminating one sound from another
Identification is actually identifying a sound and what makes it different
Sequential, step by step listening program designed to develop the use of residual hearing… what is this called?
Developmental Approach to Successful Listening
What are the three sections of DASL?
Sound awareness
Phonetic listening
Auditory comprehension
