Audiology And Hearing

Front 1

What type of energy is transferred from the middle ear to the inner ear?

Back 1

Mechanical Energy to Hydraulic Energy
(the ossicle chain transfers the mechanical energy via pushing the oval window which makes waves in the fluid filled inner ear which moves the hair cells with in the inner ear creating hydraulic energy)

Front 2

The Semicircular Canals, Saccule and Utricle comprises what inner ear system?

Back 2

Vestibular

Front 3

Myringotomy is what type of surgical procedure?

Back 3

This procedure is calls for a small incisions are made in the ear drum to release pressure from the middle ear.

Front 4

What ages should visual reinforcement and conditional play be used for evaluating hearing?

Back 4

ages 3 months to 3 years.

Front 5

What is presbycusis ?

Back 5

A hearing loss that is caused due to aging. It is considered a type of sensorineural loss.

Front 6

Define Speech Recognition Threshold.

Back 6

The lowest intensity that speech can be heard at least 50% of the time.

Front 7

Name Three assessment approaches that can be used to determine possible hearing loss

Back 7

1. Pure Tone Audiometry

2. Immittance Audiometry

3.Otoacustic Emissions

Front 8

Name the disorder that occurs when an individual has difficulty sorting auditory signals, organizing the signals and gaining information needed to respond appropriately.

Back 8

Auditory Processing Disorder

Front 9

Auditory Processing Disorder occurs when there is some for a disruption in the ________?

Back 9

Brain

Front 10

What is Total Communication?

Back 10

Total Communication is one of the various treatment is used for treating individuals with Profound hearing loss. It consist of the use of teaching both verbal and nonverbal means of communication, such as sign, speech reading,and verbal communication.

Front 11

The primary type of energy transferred through the outer ear is...

Back 11

acoustical

Front 12

Tissues

Back 12

skin, muscle, mucous membrane

Front 13

The middle ear matches the impedance of ________ and ________ in transmitting mechanical vibrations to the cochlea

Back 13

air and cochlear fluid

Front 14

At rest, under normal conditions, the nasopharyngeal ostium is

Back 14

closed

Front 15

In comparison to an adult, a child's Eustachian tube is __________ and ________.

Back 15

shorter and more horizontal

Front 16

Why do the middle ear muscles contract in response to sound?

Back 16

to protect the inner ear from loud sounds

Front 17

Organ of Corti

Back 17

sensory receptor inside the cochlea which holds the hair cells, the nerve receptors for hearing.

Front 18

High tones are coded in the ________ turns of the cochlea

Back 18

basal

Front 19

Where is hydromechanical energy transduced into bioelectrical energy

Back 19

at the organ of corti

Front 20

The central auditory pathways consist of a complex, sequential series of _________ and __________ that extend from the brainstem to the cerebral cortex and back down again.

Back 20

nuclei and fiber tracts

Front 21

Osteosclerosis

Back 21

a type of osteopetrosis that involves abnormal hardening of bone and an elevation in bone density. It can be a pathology, normally detected on a radiograph as an area of increased opacity; that is, where more mineral is present in the bone to absorb or deflect the X-ray beam.

Front 22

Typical treatment to treat constant/reoccurring ear infections in children

Back 22

pressure-equalization tubes

Front 23

Conductive hearing loss

Back 23

occurs when sound is not conducted efficiently through the outer ear canal to the eardrum and the tiny bones (ossicles) of the middle ear. Conductive hearing loss usually involves a reduction in sound level or the ability to hear faint sounds. This type of hearing loss can often be corrected medically or surgically.

Front 24

Possible causes of conductive hearing loss

Back 24

Fluid in the middle ear from colds

Ear infection (otitis media)

Allergies (serous otitis media)

Poor eustachian tube function

Perforated eardrum

Benign tumors

Impacted earwax (cerumen)

Infection in the ear canal (external otitis)

Swimmer's Ear (otitis ecxterna)

Presence of a foreign body

Absence or malformation of the outer ear, ear canal, or middle ear

Front 25

Sensorineural hearing loss

Back 25

Occurs when there is damage to the inner ear (cochlea), or to the nerve pathways from the inner ear to the brain. Most of the time, SNHL cannot be medically or surgically corrected. This is the most common type of permanent hearing loss. SNHL reduces the ability to hear faint sounds. Even when speech is loud enough to hear, it may still be unclear or sound muffled.

Front 26

Possible causes of sensorineural hearing loss

Back 26

Illnesses

Drugs that are toxic to hearing

Hearing loss that runs in the family (genetic or hereditary)

Aging

Head trauma

Malformation of the inner ear

Exposure to loud noise

Front 27

Mixed hearing loss

Back 27

When a conductive hearing loss occurs in combination with a sensorineural hearing loss (SNHL). In other words, there may be damage in the outer or middle ear and in the inner ear (cochlea) or auditory nerve. When this occurs, the hearing loss is referred to as a mixed hearing loss.

Front 28

A child with an auditory processing disorder may have a lesion or dysfunction in...

Back 28

the central auditory pathways

Front 29

Congenital abnormalities of the ear often accompanied with abnormalities in the _______, because these organs develop embryologically at the same time.
