b) would understand conversational speech only if it were loud
c) may show articulation problems in their speech
d) do not rely on hearing as their primary avenue of communication

d) all of the above
d) all of the above
In the cochlea, high frequencies are analyzed at the:
a) helicotrema
b) apex
c) base
d) near the middle
c) base
Again, more waves, more chance to be picked up at the lip of the cone that is the cochlea.
malingering is a category of:
a) tinnitus
b) presbycusis
c) non-organic loss
d) sensorineural loss
c) non-organic loss
The decibel expresses
a) the threshold of hearing
b) the ratio between two sound pressures
c) the pitch of a tone
d) the loudness of sound
d) the loudness of sound
If the battery drain of a hearing aid circuit is 2mA and the battery capacity is 250 mAH, what is the expected battery life?
a) 31.25 hours
b) 62.5 hours
c) 125 hours
d) 250 hours
c) 125 hours
Which is true of the oval window
a) it is an opening between the middle ear and the inner ear
b) it is an opening into which the stapes footplate fits
c) is the boundary line between the middle and the inner ear
d) all of the above
e) none of the above
d) all of the above
Instructions to the person being tested should be
a) unnecessary most of the time
b) carefully given and checked to see that the client understands
c) brief and to the point
d) limited only to how the client should respond
b) carefully given and checked to see that the client understands
Sound will travel fastest through
a) air
b) wood
c) steel
d) water
c) steel
Sounds travels through the bumping of particles. If the particles are dense, they bump
really fast. The problem with this question is that if the particles are so many they will stop the
sound. Think about this, and go talk through types of material and observe the effects on sound.
Presence of cerumen, size and shape of the canal can be determined by
a) the shape of the earmold
b) examination of the ear with an otoscope
c) the audiometric threshold pattern
d) use of a cotton block or an otoblock
b) examination of the ear with an otoscope
Remember, you are not just looking for wax, or abnormalities, you are looking so as to
ascertain what type of otoblock, and, eventually, what type of hearing aid, would be best recommended.
Little acoustic energy is lost in removing the eardrum
True
False
False
The eardum has no acoustic energy, it takes the impact of acoustic energy.
Before conducting audiometric tests
a) the subject’s ears should be carefully examined using an otoscope.
b) you should carefully remove impacted cerumen, if the subject so requests
c) hand the earphones to the client so that he/she can put them on in a comfortable
manner
d) none of the above
a) the subject’s ears should be carefully examined using an otoscope.
The field of electronics relating to hearing aid amplification
a) is only a study of wave forms
b) constitutes concepts difficult for the person untrained in electronics to master
c) can be mastered with a very short course of training
d) is the study of transverse wave analysis
c) can be mastered with a very short course of training
