The accepted definition of chronic tinnitus, as compared to normal ear noise experience, is five minutes of ear noise occurring at least twice a week. However, people with chronic tinnitus often experience the noise more frequently than this and can experience it continuously or regularly, such as during the night when there is less environmental noise to mask the sound.
Frequent, prolonged exposure to loud noise increases the risk of getting tinnitus, or of making it worse, so take care to avoid very loud sounds, or protect your ears against them. Wear proper ear protectors (not cotton wool) when hammering metal, using power tools or when you are near any noisy motors. Ear protection is also important if you watch live music or play in a band or orchestra. Ear protection should not be used if ordinary, everyday sounds are uncomfortable (this may be hyperacusis or oversensitivity to sound). If earplugs are worn for blocking out such sounds, it can actually make hyperacusis worse.
Besides being an annoying condition to which most people adapt, persistent tinnitus may cause anxiety and depression in some people. Tinnitus annoyance is more strongly associated with the psychological condition of the person than the loudness or frequency range. Psychological problems such as depression, anxiety, sleep disturbances, and concentration difficulties are common in those with strongly annoying tinnitus. 45% of people with tinnitus have an anxiety disorder at some time in their life.
If you have good hearing, your doctor may suggest a sound generator. These used to be called masking devices. There are two main types. One is a portable machine that produces calming sounds. The other fits to your ear like a hearing aid and produces a constant low-level noise or tone, sometimes called white noise, masking (covering up) the tinnitus. This may also help your brain get used to the tinnitus. Some people find that sound generators interfere with their hearing while they’re using them.
HSE considers that, in general, call handlers' daily personal noise exposure is unlikely to exceed the 80 dB lower exposure action value defined in the Control of Noise at Work Regulations 2005, provided good practice in the management of noise risks is followed. Call handlers should be encouraged to report to management exposure to acoustic shock incidents and management should keep a record of these reported events.
If you develop tinnitus, it's important to see your clinician. She or he will take a medical history, give you a physical examination, and do a series of tests to try to find the source of the problem. She or he will also ask you to describe the noise you're hearing (including its pitch and sound quality, and whether it's constant or periodic, steady or pulsatile) and the times and places in which you hear it. Your clinician will review your medical history, your current and past exposure to noise, and any medications or supplements you're taking. Tinnitus can be a side effect of many medications, especially when taken at higher doses (see "Some drugs that can cause or worsen tinnitus").
Depending on the cause of your deafness, your doctor may suggest you have a cochlear implant. This device turns sounds into electrical signals and uses them to directly stimulate your auditory nerve, allowing you to hear. One part of the device is put behind your ear on the outside of your head. The other part is surgically implanted in a bone (called the mastoid bone) behind your ear. It will take time and help from a therapist to get used to using a cochlear implant.

Some people experience a sound that beats in time with their pulse, known as pulsatile tinnitus or vascular tinnitus. Pulsatile tinnitus is usually objective in nature, resulting from altered blood flow, increased blood turbulence near the ear, such as from atherosclerosis or venous hum, but it can also arise as a subjective phenomenon from an increased awareness of blood flow in the ear. Rarely, pulsatile tinnitus may be a symptom of potentially life-threatening conditions such as carotid artery aneurysm or carotid artery dissection. Pulsatile tinnitus may also indicate vasculitis, or more specifically, giant cell arteritis. Pulsatile tinnitus may also be an indication of idiopathic intracranial hypertension. Pulsatile tinnitus can be a symptom of intracranial vascular abnormalities and should be evaluated for irregular noises of blood flow (bruits).

Deaf culture refers to a tight-knit cultural group of people whose primary language is signed, and who practice social and cultural norms which are distinct from those of the surrounding hearing community. This community does not automatically include all those who are clinically or legally deaf, nor does it exclude every hearing person. According to Baker and Padden, it includes any person or persons who "identifies him/herself as a member of the Deaf community, and other members accept that person as a part of the community," an example being children of deaf adults with normal hearing ability. It includes the set of social beliefs, behaviors, art, literary traditions, history, values, and shared institutions of communities that are influenced by deafness and which use sign languages as the main means of communication. Members of the Deaf community tend to view deafness as a difference in human experience rather than a disability or disease. When used as a cultural label especially within the culture, the word deaf is often written with a capital D and referred to as "big D Deaf" in speech and sign. When used as a label for the audiological condition, it is written with a lower case d.
Noise-induced hearing loss (NIHL) typically manifests as elevated hearing thresholds (i.e. less sensitivity or muting). Noise exposure is the cause of approximately half of all cases of hearing loss, causing some degree of problems in 5% of the population globally. The majority of hearing loss is not due to age, but due to noise exposure. Various governmental, industry and standards organizations set noise standards. Many people are unaware of the presence of environmental sound at damaging levels, or of the level at which sound becomes harmful. Common sources of damaging noise levels include car stereos, children's toys, motor vehicles, crowds, lawn and maintenance equipment, power tools, gun use, musical instruments, and even hair dryers. Noise damage is cumulative; all sources of damage must be considered to assess risk. In the US, 12.5% of children aged 6–19 years have permanent hearing damage from excessive noise exposure. The World Health Organization estimates that half of those between 12 and 35 are at risk from using personal audio devices that are too loud. Hearing loss in adolescents may be caused by loud noise from toys, music by headphones, and concerts or events.
An outer ear infection is sometimes called swimmer’s ear. That’s because it often starts as a result of water that remains in your ear after swimming or bathing. The moisture becomes a breeding ground for bacteria. If your outer ear is scratched or if you irritate the outer lining of your ear by putting your fingers or other objects in your ear, a bacterial infection can occur.
A conductive hearing loss reduces the ability to hear at a normal hearing level. The symptoms of a conductive hearing loss are therefore partial or full loss of hearing. The hearing loss can be in one ear or both ears. If a conductive hearing loss occurs suddenly or the hearing is reduced more and more over a short time, you should see a doctor to get your ears examined.
Rather than a disease, tinnitus is a symptom that may result from various underlying causes. The most common causes are hearing damage, noise-induced hearing loss or age-related hearing loss, known as presbycusis. Other causes include ear infections, disease of the heart or blood vessels, Ménière's disease, brain tumors, exposure to certain medications, a previous head injury, earwax, and sometimes, the tinnitus is suddenly perceived during a period of emotional stress. It is more common in those with depression.
The remedy depends on the cause of the tinnitus. There are several drugs that are used to help relieve constant ringing such as nicotinic acid, vasodilators, tranquilizers, antidepressants and seizure medications. Many times treatment is unsuccessful. Biofeedback may help in certain cases when tinnitus is related to stress. There is also tinnitus retraining therapy. You may want to explore information and support provided by the American Tinnitus Association.
Subjective tinnitus is the most frequent type of tinnitus. It may have many possible causes, but most commonly it results from hearing loss. When the tinnitus is caused by disorders of the inner ear or auditory nerve it is called otic (from the Greek word for ear). These otological or neurological conditions include those triggered by infections, drugs, or trauma. A frequent cause is traumatic noise exposure that damages hair cells in the inner ear.
