Audiology Test 1 UPDATED Exam
Questions and CORRECT Answers
Function of the Pinna? - CORRECT ANSWER - Collect sound from the environment
The Pinna- resonant frequency enhances? - CORRECT ANSWER - Speech signal near
1500Hz
Folds of the pinna help with? - CORRECT ANSWER - Localization on the same side
What is the function of the ear canal? - CORRECT ANSWER - Directs sound waves to the
ear drum, protect eardrum
What does the ear canal produce? - CORRECT ANSWER - Cerumen
Cerumen comes from what gland? - CORRECT ANSWER - Sebaceous glands located
only in cartilaginous portion
Ear canal helps protect ear from? - CORRECT ANSWER - Dust, critters, etc.
Ear canal is considered the? - CORRECT ANSWER - Resonator - it enhances acoustic
signal between 2.7k and 3.4kHz
The outer ear does what? - CORRECT ANSWER - Collects and directs sound
What does the outer ear protect? - CORRECT ANSWER - More delicate parts from
trauma, changes in temp, dust, etc.
, Outer ear also acts as a? - CORRECT ANSWER - Resonator - enhances acoustic signal in
the speech frequencies
What is the primary function of the tympanic membrane? - CORRECT ANSWER -
Transduces acoustic energy (sound wave) to mechanical energy (vibration of tympanic
membrane)
The ear drum is a large surface that collects? - CORRECT ANSWER - The force of all the
vibrating air molecules in the sound wave
The ear drum is the first step in? - CORRECT ANSWER - The middle ear transfer
function
If you didn't have a middle ear... - CORRECT ANSWER - It would be like you were
listening to like you were under water
Fluid has a ________ impedance than air, so sound waves in air tend to reflect off fluid -
CORRECT ANSWER - higher
Impedance tells us how difficult it is for? - CORRECT ANSWER - Energy to move
through the system
High impedance = ? - CORRECT ANSWER - Energy moves with difficulty
Low impedance = ? - CORRECT ANSWER - Energy moves easily
The middle ear takes the? - CORRECT ANSWER - Sound energy from air, which is
spread across the large surface of the ear drum and concentrates that energy onto the small
surface of the oval window, increase in pressure means an increase in gain
