Some nerve cells in the inner ear can signal tissue damage in a way similar to pain-sensing nerve cells in the body, according to new research from Johns Hopkins.
A summary of the research will be published online in the journal Proceedings of the National Academy of Sciences during the week of Nov. Fuchs and his team knew that these type II afferents connect to specialized sensory cells in the ear of mammals.
It was known that nearby supporting cells respond to outer hair cell damage by increasing their inner calcium levels and releasing the chemical messenger ATP.
Fuchs says that the ATP released by the supporting cells is probably what gets the neurons to fire, and the supporting cells might release ATP in response to ATP that leaks out of the ruptured outer hair cells. Over evolutionary time, such a mechanism could have evolved to help mammals avoid further damage to their hearing. The good news, Fuchs says, is that the analogies with pain elsewhere in the body provide guidance for future studies.

Our ears have built-in secret "bodyguards" that protect them from extremely loud, potentially damaging noise, researchers say.
A newly detected connection between the inner ear and the brain can warn of strong incoming noise that can cause tissue damage leading to hearing loss, researchers at Northwestern University found.
A unique pain system found only in the ear tells us to jam our fingers in our ears when that dangerously loud siren sound of an ambulance or fire engine passes us by, they explain. The ears need that special system because the kind of nerves that usually alert us to pain, when we've touched a hot burner on a stove for example, are not present in our inner ears, they've found. Instead, there's a pathway researchers have dubbed the auditory nociception pathway, separate from the pathway for transferring information about sound from the ear to the brain. This pain pathway contains just a single kind of neuron, one that is activated only by levels of noise that approach uncomfortable or dangerous intensities, the researchers report in Nature Reviews Neuroscience. Because we are exposed to noise throughout our lives and are living longer, hearing loss is the most common degenerative condition in humans, he says. The discovery of the special "bodyguard" pathway offers a new way of considering painful and intractable hearing conditions including hyperacusis, an oversensitivity to everyday sounds often seen in soldiers exposed to explosives in the military, and tinnitus, a persistent and uncomfortable ringing in the ears, the researchers say. The researchers say the ear's special pain system may be triggering a defensive autonomic reflex of stiffening the inner ear muscles to reduce the level of sound entering the ear, or at the very least sending pain messages to the brain that prompt us to take protective measures such as the good old "fingers in the ear" response to loud noises.

If the finding, discovered in rats, is confirmed in humans, it may lead to new insights into hyperacusis, an increased sensitivity to loud noises that can lead to severe and long-lasting ear pain.
These so-called outer hair cells amplify the sound waves that enter the inner ear, giving mammals very sensitive hearing over a wide range of frequencies.
Fuchs’ team knew that type II afferent neurons can respond to ATP, so they damaged outer hair cells while monitoring type II neurons in surgically removed inner ear tissue.


Such effects might depend on heightened sensitivity of the type II neurons after trauma, akin to the heightened sensitivity of pain-sensing nerves in damaged skin.
For example, a compound that suppresses pain-sensing nerve cells elsewhere, also prevented type II afferent neurons from firing in response to outer hair cell death.
Action on Hearing Loss (formerly RNID) says more than 70% of people over the age of 70 have some degree of hearing loss. It is intended for general information purposes only and does not address individual circumstances. Hypersensitivity to loud sound (hyperacusis) is a paradoxical consequence of hearing loss in many people. However, while many of us will experience gradual loss of hearing over the years, noise exposure at home, work or leisure can also cause impairment.
It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health. Everyday noises such as slamming doors, clanking dishes and barking dogs can become irritating and even painful. It's estimated that 10 million people in the UK – that's one in six - have some level of hearing loss.

Loud noise at workExposure to continuous loud noise during your working day can make you permanently hard of hearing in the long term. Jobs that are hazardous to hearing include construction, the military, mining, manufacturing, farming or transportation. The Health and Safety Executive says employers have a duty to protect employees from hearing loss. Injury damage or pressure changesTrauma to the head can impact the ear and cause permament hearing loss. Sudden pressure changes, like scuba diving or flying, can also harm the eardrum, middle ear or inner ear. While eardrums may take a few weeks to get better, serious inner ear damage may require an operation.
These are called ototoxic drugs, which may cause damage to the inner ear, resulting in hearing loss, balance problems and tinnitus. Antibiotics linked to possible permanant hearing loss include: gentamicin, streptomycin and neomycin. Chronic diseaseSome chronic diseases that are not directly linked to ear issues may trigger hearing loss. Some types of hearing loss are also linked to autoimmune diseases like rheumatoid arthritis. How you hear – anatomy of the earSound causes the eardrum and its tiny attached bones in the middle part of the ear to vibrate. The spiral-shaped cochlea in the inner ear transforms sound into nerve impulses that travel to the brain. The fluid-filled semicircular canals attach to the cochlea and nerves in the inner ear and send information on balance and head position to the brain. Growths and tumoursHearing loss can be caused by benign, non-cancerous growths, such as osteomas, exostoses or polyps that block the ear canal. A large neuroma can cause headaches, facial pain or numbness, lack of limb coordination and tinnitus.

Exposure to loud noise over 85 decibels can cause permanent hearing loss and while fireworks are lovely to watch, some can break that sound limit with a searing 155 decibels. Gunshots and other explosive noises also pack a punch to your ear, in some cases rupturing eardrums or causing damage to the inner ear. Loud concerts and tinnitusThat loud buzzing sound in the ears after a loud concert is called tinnitus. The average rock concert exposes you to sound as loud as 110 decibles which can do permamant damage after just 15 minutes. Other noises that break the 85 decibel range and risk permanent hearing loss include power tools, chain saws and leaf blowers.
Prevent tinnitus and potential hearing loss, which can last days, months or years by using earplugs and limiting noise exposure.
Personal music playersIf other people can hear the music you're listening to through your earphones, you may be at risk of permanent hearing loss.
A recent survey revealed that over 92% of young people listen to music on a personal player or mobile phone.
Recent EU standards limited the sound on these devices to 85 decibels, but many listeners plan to override the new default volume – saying they want to wipe out background noise. Action for Hearing Loss suggests using noise-cancelling headphones rather than pressing override and risking lifelong damage to your hearing. EarwaxIt may be yucky and unsightly but earwax does serve a useful purpose, protecting the ear canal from dirt and bacteria. However, if earwax builds up and hardens, it can dull your hearing and give you an earache. If you feel your ears are clogged, see your GP or nurse who may suggest olive oil drops to soften and disperse the wax. Don't be tempted to do it yourself with a cotton bud – or any other implement - which only risks damage to the ear. Childhood illnessChildren are susceptible to ear infections, which are among many childhood illnesses that can cause hearing loss. Usually, infections that fill the middle ear with fluid cause only temporary hearing loss but some may cause harm to the middle or inner ear and lead to permanent hearing loss.
Illnesses linked to hearing loss in children include chickenpox, influenza, measles, meningitis, encephalitis and mumps. Born with hearing lossIn the UK, one or two babies in every thousand are born with significant hearing loss. Although congenital hearing loss often runs in families, it can also be triggered by an infection in the mother during pregnancy. Hearing loss can also develop after lack of oxygen or trauma at birth, or if a newborn is premature. AgeRegardless of how you protect your ears, getting older reduces your hearing as you gradually lose inner ear hair cells. If you are struggling to hear and it is affecting your quality of life, go to your GP or NHS clinic to arrange a hearing test.
