{{Short description|A test used in audiology to detect non-organic hearing loss}}


The '''[[Stenger Test]]''' is a [[psychoacoustic]] test used in [[audiology]] to measure unilateral [[hearing loss]]. It is named after its inventor, [[Carl Stenger]], a German audiologist. The test is primarily used to detect non-organic or functional hearing loss, often referred to as [[malingering]].

The '''Stenger test''' is an audiological test used to identify [[non-organic hearing loss]], which is a type of hearing loss that does not have a physical or organic basis. This test is particularly useful in cases where there is a suspicion of [[malingering]] or [[functional hearing loss]].

The Stenger Test was first introduced in 1907 by Carl Stenger. Stenger was a pioneer in the field of audiology and his test has been widely used for over a century to detect cases of simulated hearing loss.

The Stenger test is based on the [[Stenger principle]], which states that when two tones of the same frequency are presented simultaneously to both ears, the listener will only perceive the louder tone. This principle is utilized to determine whether a patient is feigning hearing loss in one ear.

==Procedure==
The procedure for the Stenger test involves the following steps:


The Stenger Test is based on the [[Stenger Principle]], which states that when two identical sounds are presented simultaneously to both ears, only the louder sound is perceived. This principle is used to determine if a person is pretending to have hearing loss in one ear.
1. '''Threshold Determination''': First, the [[audiologist]] determines the pure tone thresholds for both ears using standard [[audiometry]].


== Procedure ==
2. '''Presentation of Tones''': Two tones of the same frequency are presented simultaneously to both ears. The tone presented to the "better" ear is set at 10 dB above the threshold, while the tone presented to the "poorer" ear is set at 10 dB below the threshold.


The Stenger Test is performed using a [[pure-tone audiometry]] device. The audiologist presents a tone to the suspected ear at a level that the patient claims not to hear. The same tone is then presented to the other ear at a lower level. If the patient has genuine hearing loss, they will not respond. However, if the patient is malingering, they will respond, thus revealing the deception.
3. '''Patient Response''': The patient is asked to indicate when they hear the tone. If the patient does not respond, it suggests that they are perceiving the tone in the "poorer" ear, indicating a positive Stenger test and potential non-organic hearing loss.


== Applications ==
==Interpretation==
- '''Positive Stenger Test''': If the patient does not respond, it indicates that the tone in the "poorer" ear is being perceived, suggesting non-organic hearing loss.
- '''Negative Stenger Test''': If the patient responds, it suggests that the hearing loss is organic, as the patient is perceiving the tone in the "better" ear.


The Stenger Test is used in both clinical and medico-legal settings. In clinical settings, it helps audiologists to accurately diagnose and manage patients with hearing loss. In medico-legal settings, it is used to detect cases of malingering, where individuals may pretend to have hearing loss for personal gain.
==Applications==
The Stenger test is primarily used in cases where there is a significant asymmetry in hearing thresholds between the two ears, and there is a suspicion of non-organic hearing loss. It is a quick and effective test that can be performed in a clinical setting.


== Limitations ==
==Limitations==
While the Stenger test is useful for detecting non-organic hearing loss, it does not provide information about the degree or type of hearing loss. It is also not effective in cases of bilateral non-organic hearing loss.


While the Stenger Test is a valuable tool in audiology, it has its limitations. It can only detect unilateral non-organic hearing loss and is not effective in cases of bilateral malingering. Furthermore, it requires the patient's active participation and may not be effective if the patient does not cooperate.

A test used in audiology to detect non-organic hearing loss


Stenger test[edit]

The Stenger test is an audiological test used to identify non-organic hearing loss, which is a type of hearing loss that does not have a physical or organic basis. This test is particularly useful in cases where there is a suspicion of malingering or functional hearing loss.

Principle[edit]

The Stenger test is based on the Stenger principle, which states that when two tones of the same frequency are presented simultaneously to both ears, the listener will only perceive the louder tone. This principle is utilized to determine whether a patient is feigning hearing loss in one ear.

Procedure[edit]

The procedure for the Stenger test involves the following steps:

1. Threshold Determination: First, the audiologist determines the pure tone thresholds for both ears using standard audiometry.

2. Presentation of Tones: Two tones of the same frequency are presented simultaneously to both ears. The tone presented to the "better" ear is set at 10 dB above the threshold, while the tone presented to the "poorer" ear is set at 10 dB below the threshold.

3. Patient Response: The patient is asked to indicate when they hear the tone. If the patient does not respond, it suggests that they are perceiving the tone in the "poorer" ear, indicating a positive Stenger test and potential non-organic hearing loss.

Interpretation[edit]

- Positive Stenger Test: If the patient does not respond, it indicates that the tone in the "poorer" ear is being perceived, suggesting non-organic hearing loss. - Negative Stenger Test: If the patient responds, it suggests that the hearing loss is organic, as the patient is perceiving the tone in the "better" ear.

Applications[edit]

The Stenger test is primarily used in cases where there is a significant asymmetry in hearing thresholds between the two ears, and there is a suspicion of non-organic hearing loss. It is a quick and effective test that can be performed in a clinical setting.

Limitations[edit]

While the Stenger test is useful for detecting non-organic hearing loss, it does not provide information about the degree or type of hearing loss. It is also not effective in cases of bilateral non-organic hearing loss.
