Exam 1 Progress Checks HTM

A "positive" outcome for which test(s) indicate(s) normal hearing or a sensorineural loss?

Rinne and bing test

Which of the following makes it easier to hear sounds presented by bone conduction?

Occluding the outer ear

When hearing by bone conduction, which structures are set into vibration?

The bones of the head

Marching band frequency and intensity

Mid frequency

High intensity

Siren

High frequency

High intensity

Water dripping frequency and intensity

Low frequency

Low intensity

Leaves rustling frequency and intensity

Mid frequency

Low intensity

Which of the following is the most common site for a sensorineural hearing loss?

The inner ear

Which parts of the auditory system make up the conductive mechanism?

The outer and middle ear

Imagine that you are one of the first audiologists. To which of these societies would you most likely belong?

ASHA

Dispensing or rehabilitative audiology takes place primarily....

In Private audiology practices

Air conduction hearing is dependent upon the integrity of the auditory system from the: 

Outer ear to brain (auditory cortex)

A spectogram is a display of frequency and intensity as a function of (Answer 1). (Answer 2) is displayed on the y-axis, while (Answer 3) is indicated by the darkness of the display.

Time

Frequency

Intensity

When you tap a crystal goblet with a spoon, it makes a bell-like sound that lasts for a long time. This is an example of (Answer 1) damping. In contrast, if you hit a bass drum with a mallet, it makes a booming sound that ends quickly but not immediately. This is an example of (Answer 2) damping.

Light

Heavy

When looking at pure tones displayed on an oscilloscope, what does increasing the frequency of the tone do to the display?

There will be more waves on the screen

Which aspect of sound most closely correlates with loudness?

Amplitude

What is the interrupter switch on an audiometer used for?

To turn the signal on or off

Using otoscopy looking at a normal right tympanic membrane, which landmark should be visible in the anterior inferior quadrant?

Cone of light

SLP referred because

Hearing loss needs to be ruled out as a factor contributing to developmental problems.

Otolaryngologist referred because

Hearing needs to be assessed prior to surgery.

Neurologist referred because

There are concerns about possible central auditory nervous system involvement.

Members of patients family referred because

Family members have been having difficulty communicating with the patient.

The patient referred because

the patient has been having difficulty hearing and understanding speech.

Pressure is placed on the external ear canal to:

Check for collapsing ear canal

The tympanic membrane is composed of three layers. What is the most medial* layer made of? [Medial=innermost with reference to the body].

Mucous membrane

What are three major landmarks the examiner looks for during an otoscopic examination?

Malleus, umbo, annulus

An air-bone gap suggests:

Conductive hearing loss

The occlusion effect

happens when testing bone-conduction and one or both ears are covered with earphones.

[ written on an audiogram means:

Right ear masked bone conduction, mastoid placement

The interaural attenuation (IA) when using insert phones is:

Higher than the IA when using supra-aural headphones

The masking dilemma is the problem occurring when

The unmasked audiogram reveals large air-bone-gaps in both ears causing the initial masking level to already be overmasking

In the plateau method of masking when the masking noise crosses over to the test ear, what part of the plateau does this respresent?

Overmasking

Plateau components

Under masking

Plateau

Overmasking

The level of noise that can be varied over a small range that does not alter the threshold of a sound presented to the opposite ear.

Plateau

Drawback of forehead placement

Higher voltage required

What level is the initial masking (IM) level for air conduction in the NTE?

15 dB SL

Introduction of noise into the nontest ear to eliminate cross-hearing is called

Clinical masking

For bone conduction, masking is necessary when the air conduction threshold of the test ear and the bone conduction threshold of the test ear differ by

More than 10 dB
