❒ Vision Problems: Some people suffering from problems of the inner ear experience disturbance in normal vision. Blurry or double vision with sensitivity to bright light is also a common problem. Some people may experience bouncing or jumping vision. Any visual stimulation may trigger dizziness. This happens because an inflammatory condition in the inner ear may put some amount of pressure on certain ocular nerves.
Outer ear infection: otitis externa – usually affects adults aged 45 to 75. It affects the ear canal and is often caused by bacterial infection of the skin of the canal, or a fungus or a yeast. It can also be caused by an irritation such as wearing earplugs or a hearing aid. It is common in people who suffer from skin problems such as eczema, psoriasis or dermatitis but also in people who are keen swimmers.
In addition to medications, hearing loss can also result from specific chemicals in the environment: metals, such as lead; solvents, such as toluene (found in crude oil, gasoline[67] and automobile exhaust,[67] for example); and asphyxiants.[68] Combined with noise, these ototoxic chemicals have an additive effect on a person's hearing loss.[68] Hearing loss due to chemicals starts in the high frequency range and is irreversible. It damages the cochlea with lesions and degrades central portions of the auditory system.[68] For some ototoxic chemical exposures, particularly styrene,[69] the risk of hearing loss can be higher than being exposed to noise alone. The effects is greatest when the combined exposure include impulse noise.[70][71] A 2018 informational bulletin by the US Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) introduces the issue, provides examples of ototoxic chemicals, lists the industries and occupations at risk and provides prevention information.[72]
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.
A lot of people have found that using background sound helps them – this can be a radio, music, or using natural sounds. People are really good at figuring out ways of making things better for themselves and you might already be aware that you generally don’t notice the tinnitus as much when there is background noise. By using sound at other times, you’re just using other ways of doing what you already know to be helpful.
Tinnitus is extremely common. Nearly everyone has experienced tinnitus (for example after noisy events or in very quiet environments) 10 per cent of the population experience tinnitus on a regular basis. In about 1-2 per cent of people tinnitus is sufficient to cause distress. However we know that putting anyone in a sufficiently quiet environment will allow them to perceive tinnitus.

A 2005 study achieved successful regrowth of cochlea cells in guinea pigs.[119] However, the regrowth of cochlear hair cells does not imply the restoration of hearing sensitivity, as the sensory cells may or may not make connections with neurons that carry the signals from hair cells to the brain. A 2008 study has shown that gene therapy targeting Atoh1 can cause hair cell growth and attract neuronal processes in embryonic mice. Some hope that a similar treatment will one day ameliorate hearing loss in humans.[120]
Hyperacusis is an increased sensitivity to sound. If you find that everyday or ordinary sounds are uncomfortable, you may have hyperacusis. Whilst it might seem natural to want to block out as much sound as possible, avoiding sound can actually make hyperacusis worse. Talk to your GP about this and ask for a referral to either an ENT Surgeon or Audiovestibular Physician who will be able to suggest management options – often, using sound (in a very controlled way) can improve hyperacusis.

Ménière’s disease is a long term, progressive condition affecting the balance and hearing parts of the inner ear. It most commonly affects people aged 20-60. It’s uncommon in children. People suffering from this disease experience: dizziness with a spinning sensation, feel unsteady, feel or are sick, hear ringing, roaring or buzzing inside the ear or a sudden drop in hearing.
Acoustic qualification of tinnitus will include measurement of several acoustic parameters like frequency in cases of monotone tinnitus or frequency range and bandwidth in cases of narrow band noise tinnitus, loudness in dB above hearing threshold at the indicated frequency, mixing-point, and minimum masking level.[52] In most cases, tinnitus pitch or frequency range is between 5 kHz and 10 kHz,[53] and loudness between 5 and 15 dB above the hearing threshold.[54]
Hyperacusis escalation is common with ASD so that an increasing range of sounds become intolerable, with a corresponding escalation in TTTS symptoms, potentially leading to TMD. For this reason, a detailed history is essential in tracking the order of development and escalation of symptoms, and their relationship to acoustic incidents/headset use, prior to making a responsible and considered diagnosis of ASD.
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.
Barotrauma unequal air pressures in the external and middle ear.[3] This can temporarily occur, for example, by the environmental pressure changes as when shifting altitude, or inside a train going into a tunnel. It is managed by any of various methods of ear clearing manoeuvres to equalize the pressures, like swallowing, yawning, or the Valsalva manoeuvre. More severe barotrauma can lead to middle ear fluid or even permanent sensorineural hearing loss.
Depression is one of the leading causes of morbidity and mortality worldwide. In older adults, the suicide rate is higher than it is for younger adults, and more suicide cases are attributable to depression.[38] Different studies have been done to investigate potential risk factors that can give rise to depression in later life. Some chronic diseases are found to be significantly associated with risk of developing depression, such as coronary heart disease, pulmonary disease, vision loss and hearing loss.[39] Hearing loss can attribute to decrease in health-related quality of life, increase in social isolation and decline in social engagement, which are all risk factors for increased risk of developing depression symptoms.[40]
The initial physiological symptoms of acoustic shock are considered to be a direct consequence of excessive, involuntary middle ear muscle contractions. While the stapedial reflex is an acoustic reflex triggered by high volume levels, the tensor tympani reflex is a startle reflex (6, 7) which is exaggerated by high stress levels. The tensor tympani muscle contracts immediately preceding the sounds produced during self-vocalisation, suggesting it has an established protective function to loud sounds (1), assists in the discrimination of low frequency sounds (8), and is involved in velopharyngeal movements (8).

Besides research studies seeking to improve hearing, such as the ones listed above, research studies on the deaf have also been carried out in order to understand more about audition. Pijil and Shwarz (2005) conducted their study on the deaf who lost their hearing later in life and, hence, used cochlear implants to hear. They discovered further evidence for rate coding of pitch, a system that codes for information for frequencies by the rate that neurons fire in the auditory system, especially for lower frequencies as they are coded by the frequencies that neurons fire from the basilar membrane in a synchronous manner. Their results showed that the subjects could identify different pitches that were proportional to the frequency stimulated by a single electrode. The lower frequencies were detected when the basilar membrane was stimulated, providing even further evidence for rate coding.[130]


Most tinnitus is subjective, meaning that only you can hear the noise. But sometimes it's objective, meaning that someone else can hear it, too. For example, if you have a heart murmur, you may hear a whooshing sound with every heartbeat; your clinician can also hear that sound through a stethoscope. Some people hear their heartbeat inside the ear — a phenomenon called pulsatile tinnitus. It's more likely to happen in older people, because blood flow tends to be more turbulent in arteries whose walls have stiffened with age. Pulsatile tinnitus may be more noticeable at night, when you're lying in bed and there are fewer external sounds to mask the tinnitus. If you notice any new pulsatile tinnitus, you should consult a clinician, because in rare cases it is a sign of a tumor or blood vessel damage.
Conductive hearing loss occurs when sounds aren’t able to travel from the outer ear to the eardrum and the bones of the middle ear. When this type of hearing loss occurs, you may find it difficult to hear soft or muffled sounds. Conductive hearing loss isn’t always permanent. Medical interventions can treat it. Treatment may include antibiotics or surgical interventions, such as a cochlear implant. A cochlear implant is a small electrical machine placed under your skin behind the ear. It translates sound vibrations into electrical signals that your brain can then interpret as meaningful sound.

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").


Noise exposure is the most significant risk factor for noise-induced hearing loss that can be prevented. Different programs exist for specific populations such as school-age children, adolescents and workers.[87] Education regarding noise exposure increases the use of hearing protectors.[88] The use of antioxidants is being studied for the prevention of noise-induced hearing loss, particularly for scenarios in which noise exposure cannot be reduced, such as during military operations.[89]
Acoustic qualification of tinnitus will include measurement of several acoustic parameters like frequency in cases of monotone tinnitus or frequency range and bandwidth in cases of narrow band noise tinnitus, loudness in dB above hearing threshold at the indicated frequency, mixing-point, and minimum masking level.[52] In most cases, tinnitus pitch or frequency range is between 5 kHz and 10 kHz,[53] and loudness between 5 and 15 dB above the hearing threshold.[54]
Fluid accumulation is the most common cause of conductive hearing loss in the middle ear, especially in children.[2] Major causes are ear infections or conditions that block the eustachian tube, such as allergies or tumors.[2] Blocking of the eustachian tube leads to decreased pressure in the middle ear relative to the external ear, and this causes decreased motion of both the ossicles and the tympanic membrane.[3]

Vertigo is the subjective sensation of the surroundings moving or spinning. It is a symptom of inner ear disease (peripheral) or disorders associated with the brain (central). The cause of many cases of vertigo are unknown (idiopathic) although peripheral vertigo may be related to infection, trauma or chemical irritation of the semicircular canals. Central vertigo may be seen in conditions like multiple sclerosis or strokes.

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.

^ "Childhood hearing loss: act now, here's how!" (PDF). WHO. 2016. p. 6. Archived (PDF) from the original on 6 March 2016. Retrieved 2 March 2016. Over 30% of childhood hearing loss is caused by diseases such as measles, mumps, rubella, meningitis and ear infections. These can be prevented through immunization and good hygiene practices. Another 17% of childhood hearing loss results from complications at birth, including prematurity, low birth weight, birth asphyxia and neonatal jaundice. Improved maternal and child health practices would help to prevent these complications. The use of ototoxic medicines in expectant mothers and newborns, which is responsible for 4% of childhood hearing loss, could potentially be avoided.
Ringing, buzzing, or roaring in the ears is often used to describe tinnitus, which can be extremely annoying and occur without any reason. Tinnitus may signify underlying nerve damage or an issue with your circulatory system, or there may not be a clear reason for the problem, so it is best to consult your doctor.[1] One way to stop ringing in your ears is prevention, but the issue may also be genetic and you cannot control this. There are steps that you can take to treat the ringing buzz even after the damage is done. Read on for helpful hints and tips.
Is conductive hearing loss curable? Yes, often. Most cases of conductive hearing loss are temporary and are cured by means of appropriate medical treatment, so it is important to seek immediate medical assistance. Other types of conductive hearing losses can be treated with hearing aids or types of hearing implants. Finally, some types of conductive hearing loss can be treated through surgery.
Tinnitus is usually more noticeable in a quiet environment. It’s a bit like candles on a birthday cake – in the lights, the candles aren’t very bright but if you turn the lights off, the candles seem much brighter. With tinnitus, when there is other sound, it doesn’t seem that loud, but when you turn all the other sound off, the tinnitus seems much more noticeable.
If your hearing loss is caused by a bacterial infection of the outer ear canal, your doctor may prescribe antibiotic drops. Antibiotics taken by mouth are usually prescribed only for very severe middle ear infections. Ask your pharmacist for advice on your medicine, and always read the patient information leaflet that comes with it. If you keep getting ear infections, your doctor may refer you to a specialist.
Conductive hearing loss results when there is any problem in delivering sound energy to your cochlea, the hearing part in the inner ear. Common reasons for conductive hearing loss include blockage of your ear canal, a hole in your ear drum, problems with three small bones in your ear, or fluid in the space between your ear drum and cochlea. Fortunately, most cases of conductive hearing loss can be improved.
High-pitched ringing. Exposure to a very loud noise or a blow to the ear can cause a high-pitched ringing or buzzing that usually goes away after a few hours. However, if there's hearing loss as well, tinnitus may be permanent. Long-term noise exposure, age-related hearing loss or medications can cause a continuous, high-pitched ringing in both ears. Acoustic neuroma can cause continuous, high-pitched ringing in one ear.
If your hearing loss is caused by a build-up of earwax, it will need to be removed. You may be able to have this done at your surgery by syringing. Warm water is flushed into your ear canal to remove the wax. But first the wax has to be softened by applying olive oil or almond oil drops, or drops containing sodium bicarbonate, for several days beforehand. You can buy these drops from your local pharmacy. In some cases, you may have to go to a specialist clinic to have wax removed by syringing or with microsuction.

Rather than a disease, tinnitus is a symptom that may result from various underlying causes.[2] The most common causes are hearing damage, noise-induced hearing loss or age-related hearing loss, known as presbycusis.[2] 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.[2][4] It is more common in those with depression.[3]


If there is no obvious cause of hearing loss, your doctor can refer you for a hearing assessment with an audiologist or an ear nose and throat (ENT) specialist. They will look into your ears and test your hearing to see how well you can detect different levels of sound. This assessment will help find the cause of your hearing loss and what treatments would work best.

Tinnitus is very common and is reported in all age groups, even young children. About 30% of people will experience tinnitus at some point in their lives but the number of people who live with persistent tinnitus is approximately 13% (over 1 in 8). Tinnitus is more common in people who have hearing loss or other ear problems, but it can also be found in people with normal hearing.
Acoustic neural stimulation is a relatively new technique for people whose tinnitus is very loud or won’t go away. It uses a palm-sized device and headphones to deliver a broadband acoustic signal embedded in music. The treatment helps stimulate change in the neural circuits in the brain, which eventually desensitizes you to the tinnitus. The device has been shown to be effective in reducing or eliminating tinnitus in a significant number of study volunteers.
Can ear wax cause hearing loss? Yes, one of the most common causes of conductive hearing loss is a blockage in the external ear canal, usually caused by wax (excessive cerum). Other causes of conductive hearing loss can be infections of the ear canal, a perforated or ruptured eardrum (tympanic membrane), very small ears, cysts and tumours, or foreign objects in the ear canal. Otosclerosis, which is an abnormal growth of bone in the middle ear, can also cause a conductive hearing loss.
When the sound waves reach the inner ear, they travel through the fluids of the cochlea. The cochlea is a snail-shaped structure in the inner ear. In the cochlea, there are nerve cells with thousands of miniature hairs attached to them. These hairs help convert the sound wave vibrations into electrical signals that then travel to your brain. Your brain interprets these electrical signals as sound. Different sound vibrations create different reactions in these tiny hairs, signaling different sounds to your brain.
A 2017 report by the World Health Organization estimated the costs of unaddressed hearing loss and the cost-effectiveness of interventions, for the health-care sector, for the education sector and as broad societal costs.[103] Globally, the annual cost of unaddressed hearing loss was estimated to be in the range of $750–790 billion international dollars.
Hearing loss can also result from taking certain medications. “Ototoxic” medications damage the inner ear, sometimes permanently. Some ototoxic drugs include medicines used to treat serious infections, cancer, and heart disease. Some antibiotics are ototoxic. Even aspirin at some dosages can cause problems. Check with your doctor if you notice a problem while taking a medication.
Your ear consists of three major areas: outer ear, middle ear and inner ear. Sound waves pass through the outer ear and cause vibrations at the eardrum. The eardrum and three small bones of the middle ear amplify the vibrations as they travel to the inner ear. There, the vibrations pass through fluid in a snail-shaped structure in the inner ear (cochlea).
If you are referred to a specialist tinnitus clinic, and your tinnitus is particularly troublesome, you will be introduced to more formal or structured ways of managing tinnitus. Most centres use a combination of approaches. You may come across some terms before, or hear them when you get there, and it helps to have some understanding of what these terms are.
Tinnitus is commonly described as a ringing in the ears, but it also can sound like roaring, clicking, hissing, or buzzing. It may be soft or loud, high pitched or low pitched. You might hear it in either one or both ears. Roughly 10 percent of the adult population of the United States has experienced tinnitus lasting at least five minutes in the past year. This amounts to nearly 25 million Americans.
