Term
A type B tympanogram with a high ear canal volume may be indicative of...? |
|
Definition
Pressure equalizing tubes or perforated ear drum |
|
|
Term
A type B tympanogram with normal Ear Canal Volume may indicate what? |
|
Definition
|
|
Term
measure of contraction of the stapedius and tensor tympani muscles |
|
Definition
|
|
Term
easures the sound reflected from the ear drum while the pressure of the external canal is varied by the operator. It aids in the assessment of outer ear, middle ear and the Eustachian tube. This test should not be performed in infants below the age of 7 months because the suppleness of the cartilage of the external canal may produce misleading results. |

Term
Name and explain the 5 types of tympanograms |
|
Definition
What is Type A (normal)
Type AS (abnormal) peak at 0, no amplitude, low compliance, scaring or growth
Type AD (abnormal) high compliance, break in chain, head injury
Type B (abnormal) High volume Normal volume
Type C (abnormal) everything normal but pressure, infections, allergies, eustacian tube |

Term
SRT should be in agreement with the _______ within _____dB HL. |

Term
Characteristics of a conductive hearing loss |
|
Definition
Usually temporary Can usually be treated medically or surgically Simply reduces the volume of signal Maximum loss of 60 dB |
|
|
Term
What are the 3 main components of the ABR |
|
Definition
|
|
Term
Characteristics of a sensorineural hearing loss |
|
Definition
Usually permanent Usually cannot be treated medically or surgically Reduces volume of signal AND reduces clarity of signal (i.e., reduced frequency resolution) Can range from mild to profound |
|
|
Term
Explain/describe conditioned play audiometry |
|
Definition
Testing can usually be conducted under headphones or with inserts for ear specific information. I usually tell them they are going to look like a bug/butterfly or wear a special hat. Testing is transformed into a game for the child with the use of various methods (throwing a block into a bucket, slapping your hand, touching their nose, etc. Must keep the game very simple and not complicated!!!! Children that can be conditioned to the task can provide us with a complete audiometric picture in most cases. |
