If you are listening to music or something else, keep the volume at a safe level and only listen in areas that are not noisy.

What is functional hearing loss?

FUNCTIONAL hearing loss is a term applied to all nonorganic deafness. It is a condition in which the patient does not fully utilize his residual hearing as determined by numerous available tests for detecting organic loss in auditory acuity.

What is the most common type of hearing loss?

Sensorineural hearing loss

The most common type of hearing loss is sensorineural. It is a permanent hearing loss that occurs when there is damage to either the tiny hair-like cells of the inner ear, known as stereocilia, or the auditory nerve itself, which prevents or weakens the transfer of nerve signals to the brain.

What medication causes hearing loss?

Commonly used medicines that may cause hearing loss include: Aspirin, when large doses (8 to 12 pills a day) are taken. Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen. Certain antibiotics, especially aminoglycosides (such as gentamicin, streptomycin, and neomycin).

How is hearing loss diagnosed?

There are a variety of tests available to accurately diagnose the type and severity of hearing loss. These include: Air Conduction, Conventional or Standard Audiometry This test is commonly used to measure the hearing of adults and older children.

What is Weber and Rinne test?

What are Rinne and Weber tests? Rinne and Weber tests are exams that test for hearing loss. They help determine whether you may have conductive or sensorineural hearing loss. This determination allows a doctor to come up with a treatment plan for your hearing changes.

What is Weber test for hearing?

Weber test: Place the base of a struck tuning fork on the bridge of the forehead, nose, or teeth. In a normal test, there is no lateralization of sound. With unilateral conductive loss, sound lateralizes toward affected ear. With unilateral sensorineural loss, sound lateralizes to the normal or better-hearing side.

What is functional hearing loss?

FUNCTIONAL hearing loss is a term applied to all nonorganic deafness. It is a condition in which the patient does not fully utilize his residual hearing as determined by numerous available tests for detecting organic loss in auditory acuity.

What is positive Rinne test?

The patient should be able to hear the sound of the tuning fork adjacent to their ear, persist for approximately twice as long as the sound they heard over their mastoid process. This is considered a “positive test.”
