Eye and Ear first identified this novel type of sensorineural damage after noise exposure and dubbed it
cochlear synaptopathy
, or hidden hearing loss. “People with hearing loss in one ear are often reluctant to engage in rehabilitation or treatment as they still can rely on the better ear.
There is no direct treatment
, although research is underway to find medications that would prompt neurons to grow new synapses. In cases where there’s at least slight or mild hearing loss, people will benefit from state-of-the art hearing aids that have “speech in noise” settings.
Kujawa found something surprising: The ears
of people who had been exposed to noise kept getting worse over time
, faster than in those without noise damage.
Is Hidden hearing loss common?
While the condition is more common in older adults (over the age of 65),
hidden hearing loss affects all ages
and is dependent upon the underlying mechanism and cause. For example, young adults with noise exposure experience it. In some cases, traumatic brain injuries may also cause hidden hearing loss.
There’s no cure for hidden hearing disorder
, but there are communication strategies — and even some nifty technologies — that can reduce the impact of noise on listening and lessen further damage.
Preview. What’s been hidden in hidden hearing loss. Human studies of potential effects of cochlear neurodegeneration on perception have focused on impoverished input coding as the driver, with mixed results. A new study instead points to altered brain dynamics in noise as the proximal cause of hearing difficulties.
Can you pass a hearing test but still have problems hearing?
Typically,
you can only pass a hearing test but still have problems hearing if you have a narrow test
. A comprehensive hearing examination should investigate your ability to interpret a variety of sound environments, not just pure tones.
Can hear but not understand?
For some people, hearing but not understanding may signal
an auditory processing disorder (APD)
. This means the nervous system—not the ears—struggles to make sense of the sounds coming in from the ears. APD is often diagnosed in children, but it also can be diagnosed in adults.
A hidden hearing loss is a type of hearing loss that cannot be measured by the most common hearing test. On suspicion of a hearing loss, the first step is to measure the hearing with an
audiogram
, but for people with hidden hearing loss, the audiogram looks as it does for someone with normal hearing.
What are the different levels of hearing loss?
| Degree of hearing loss Hearing loss range (dB HL) | Mild 26 to 40 | Moderate 41 to 55 | Moderately severe 56 to 70 | Severe 71 to 90 |
|---|

- surgery to repair the ear or remove a tumor.
- antibiotics to treat infection.
- steroids to reduce inflammation and swelling.
- stopping use of the medication that may be causing the hearing loss.
What is a normal hearing test result?
The results of the hearing test are an indication for the degrees of hearing loss: Normal hearing:
-10 to 20 dB
. Mild hearing loss: 20 to 40 dB higher than normal. Moderate hearing loss: 40 to 70 dB higher than normal.
Can u get tinnitus in one ear?
Most people experience tinnitus in both ears, called bilateral tinnitus.
Less commonly it develops in only one ear
, called unilateral tinnitus. Tinnitus may be a sign of injury or dysfunction of the inner ear, and is often associated with age- or noise-related permanent hearing loss.
Why old people Cannot hear clearly?
There are many causes of age-related hearing loss. Most commonly, it arises from
changes in the inner ear as we age
, but it can also result from changes in the middle ear, or from complex changes along the nerve pathways from the ear to the brain. Certain medical conditions and medications may also play a role.
