During this time Audiology became an independent profession
What is WWII?
Source-filter theory is
What is related to acoustics phonemes to articulation

(2) Filter- sounds are manipulated through articulatory cavities
Function of the pinna
What are collect sound, localization, resonator, and protection?
True or False
Case history forms are discipline and age-specific
True
An air-bone gap greater than ____ dB HL indicates a conductive HL
ASHA requires an AuD and SLP to complete this amount of hours of continuing education in a 3-year period
What is 30 hours?
4 components of sound
What is:
(1) Source of vibration, (2) Medium for sound to travel through, (3) Hearing mechanism, (4) Brain to interpret
Basilar membrane properties
Base- narrow, stiff, high frequency

What is the: (1) correct language used, (2) good visibility/line of sight for all, (3) adequate lighting, (4) ALWAYS address patient directly, never the interpreter?
A SNHL is & what we see with this loss im AC and BC testing & is there an air-bone gap
What is something is the neural part of the auditory system isn't working properly
AC test = hearing loss
BC = hearing loss
*NO AIR-BONE GAP*
Government involvement assisted in treating these areas to compensate soldiers
What is:

- disease
- acoustic trauma
- emotional trauma
We describe and perceive sound in this way
What is:
Description- frequency, amplitude, duration, phase)
Perception- pitch, loudness, length, location
Auditory primary pathway
What is ventral cochlear nucleus --> superior olive --> inferior colliculus --> MGN --> auditory cortex?
Why do we ask questions for clinical interviews?
What is:
(1)secure information, (2) clarify statements, (3) explore various thoughts that have been expressed, (4) motivate people to communicate, (5) direct the focus of conversations
