Conductive Hearing Loss
|
This type of loss results when there is damage to the structure/functions of the middle ear.
This type of loss is seen on an audiogram with an air-bone gap. |
|
Sensorineural Hearing Loss
|
This type of loss results when there is damage to the structures/function of the inner ear or the auditory nerve (CN-8).
|
|
Mixed Hearing Loss
|
This type of loss has both conductive and sensorineural components.
|
|
Type A Tympanogram
|
This reflects normal functioning of the middle ear.
|
|
Type As Tympanogram
|
This reflects a stiffness or otherwise partial loss of mobility of the stapes. There is still normal pressure in the middle ear.
|
|
Type Ad Tympanogram
|
This reflects a disconnection of the bones of the middle ear, or a tympanic membrane that is operating with flaccidity.
|
|
Type B Tympanogram
|
This reflects fluid in the middle ear.
|
|
Type C Tympanogram
|
This reflects negative pressure in the middle ear.
|
|
Pure Tone Audiometer
|
This is used to determine hearing thresholds. Most have the capability to test for air-conduction and bone-conduction thresholds, and can also use masking.
|
|
Masking
|
This is a type of procedure used during audiometry in which noise is introduced in the non-test ear in order to control for cross-hearing.
|
|
Speech Detection Threshold- SDT
|
This is a type of speech audiometry. It is the lowest level at which speech can be detected.
|
|
Speech Recognition Threshold-SRT
|
This is a type of speech audiometry. It is the lowest level at which 50% of speech is understood.
|
|
Most Comfortable Loudness Level- MCL
|
This is the level at which most speech is deemed comfortably loud.
|
|
Uncomfortable Loudness Level-UCL
|
This is the level at which speech is deemed uncomfortably loud, and is an important measurement when fitting or considering hearing aids.
|
|
Dynamic Range for Speech
|
This is the range between the SRT and the UCL, and is a comfortable range of speech.
|
|
Play Audiometry
|
This type of audiometry is used when testing young children. Children are taught to put a bead on a string/in a bucket, etc when they hear a sound.
