You probbably have some water in your ear,if so put some perioxide in it, lay your head on the floor flat and then get up after you can no longer hear the noise.If this is not it it could be tinnitus, the cause is "palatal myoclonus" A muscle spasm in the palate is wiggling the eustachian tubes from the mouth end, and you hear a sound at the ear end when the tubes open. \nhope it helps you:)

If your PCB has a hairline crack and conducting path is intermittent. A sound that is converted into a vibration can cause induced interference at the hairline crack.\n\nBut this is via a transducer (hairline crack), not directly from sound to electrical. This principle was used in the early days on the carbon microphone for the telephone mouth piece.

check your pads, if it looks like the thin paper like layer is torn or damaged in any way, you may need to replace your pads, usually they need to be changed about once a year, it can also effect your tone quality if these do need to be replaced

The high pitched sounds you describe sound like a condition called "tinnitus". You might get more information if you look for that word, for example with an internet search engine.\n\nHave you seen an Audiologist as well as a Neurologist? If not, it might help as they may be able to give you more information and support.

Think I'd check with ear specialist.  I can't fly without taking certain meds so that I don't perforate my ear drum.

Gonna have to go to the doc for this one, Hon.  It could be a couple of things.  Maybe, an inner ear infection.  And you would need antibiotics.

Tinnitus is more of a ringing in the ear - Sounds more like a circulation thing - the blood vessels in the ear are some of the thin-est in the body. - even a slight constriction will sound like a drum - you're likely hearing the sound of blood trying to get through after every heart beat. - My mom had carotid surgery for blockage, and before she did the noise in her ear was deafening - she said it was like rushing water - actually kept her from sleeping. - I'd see a Dr. - Just to be funny, you could try some aspirin or Tylenol (thinner, anti-coagulant) and see if there's a difference. - If there is, it's probably a circulatory thing. - an ultrasound will confirm, but a Dr. should be able to listen with a stethoscope and get an idea if you've got some pathways that are blocked. - Do get it checked. - Depending on your age and health, blockages can lead to stroke. - Hope it's nothing at all.

Hello Bro,\n\n              There are many ways of looking at it.\nJust read the article below which throws light on how many hings can cause the problem you ae talking about. In summary, things that could cause the problems are:\n\n1.) A hard impact in the wrong place causing clot and clot bursting sometime later crwating a haemorrage.\n2.) Hereditary\n3.) Disease - Diabetes (which could also be herditary\n4.) Wrong drugs.\n\nAll i can say is the person having this problem needs immediate medical attention.\n\nRead the article below for more info.\n\nKeep hearing loss at bay \n\nDr. SHAILAJA NIKAM \n\nThere are many causes for losing one's hearing. Early identification is crucial to prevent or minimise loss of hearing.  \n\n\n\n\n\nPREVENTING loss of hearing must constitute a major programme for the well being of an individual. Efforts on the part of the State as well as the individual are required towards prevention — primary, secondary and tertiary. \n\nPrimary prevention requires the State to initiate programmes like immunisation against diseases, providing prenatal care, initiating neonatal screening programmes in the hospitals and hearing screening in schools. \n\nLegislation to keep noise levels within prescribed limits and a mandatory hearing conservation programme in industries are other measures. Efforts at the individual level must supplement the State initiatives. \n\nWhy wax? \n\n\nNature has provided glands that produce wax to keep foreign bodies like insects from entering the ear. The wax moves on its own towards the opening of the ear canal. Using sharp objects to remove wax harms the ear canal wall and the eardrum. Swimmers must ensure that the pool is clean. Use of earplugs can prevent contact with contaminated waters. \n\nThe Eustachian tube is the link between the middle ear and the back of the throat. It opens during yawning and swallowing. The exchange of air during this process helps in maintaining a proper balance of air pressure on both sides of the eardrum, which is essential for good hearing \n\nNot many know that fluid accumulation in the ear is detrimental to good hearing and can also damage the ear structures. So, ears must be kept free of discharge, which is caused by poor ventilation of the middle ear. \n\nFluid secreted by the mucous lining of the middle ear fills the vacuum. Fluid fills the space normally occupied by air in the middle ear. Thus ensuring good ventilation of the ear through a patent Eustachian tube is a potent preventive measure. \n\nInflammation \n\n\nOtitis media or inflammation of the middle ear can be acute, secretory or chronic. Acute otitis media is caused by general infection such as measles, chicken pox, or infection conveyed to the ear through blood stream. \n\nMore commonly, it is due to infection spreading through the nose, nasopharynx, and sinuses via the Eustachian tube. Due to inflammation, the swollen Eustachian tube does not drain the pus. So, the fluid or pus is retained in the middle ear cavity. The pus may escape or drain through a ruptured or incised tympanic membrane, the eardrum. \n\nIn case the thin partition between the middle ear and the brain is unable to obstruct the pus, it may break through the partition and cause meningitis. \n\nTreatment for otitis media should not be looked upon as complete until the tympanic membrane appears normal and hearing is fully restored. \n\nHearing loss may continue if the treatment is inadequate and if the infection comes through the Eustachian tube. Hence, the source of infection in the sinus and the nasopharynx must be treated fully. \n\nInfection \n\n\nMeasures aimed at primary prevention call for elimination of the causal agents, especially the viral and bacterial diseases known to cause hearing loss. Examples are typhoid, mumps, and measles. Hearing loss may also be secondary to chicken pox. \n\nTreatment for the infectious diseases must be sought and completed fully. Inadequate doses taken for an insufficien

If you have really tense neck muscles, this can cause  blockage. Sometimes related to ear aches.

You've got tinnitus.  I have it too.  There's nothing to cure it, although there's some new herbal type pill that claims to reduce the ringing.  I don't believe it.  I've had tinnitus since I was a child.  It came from a very severe dual ear infection that damaged my eardrums.  At night, it's the worst due to the silence.  I meditate to help ignore the ringing & to relax into sleep.  I've been told one day, I'll have to wear hearing aids.  I get my hearing checked every 6 months too.  I've got 9% hearing loss in both ears & I'm just 33.

It could be fluid from cold or allergies, an ear infection, or wax blockage. DON'T stick anything in your ear - you could damage your eardrum. See a doctor, who can look inside and determine what the problem is.

Could be 'altitude deafness' caused by too much air pressure on the eardrum from inside the middle ear which is not being equalized. This can happen if the eustachian tube is blocked, plugged or inflamed. An easy remedy during a cold is by using decongestant nasal drops.

Well, do you drink? Do drugs? Smoke? What do you think of prostitutes? Maybe it's the environment which makes you uncomfortable.\nAlso, that techno/disco music can be too loud for your ear's sensitivity so it can make you dizzy or feel sick.

You should go see a doctor you may have ear damage. If you listen  to very loud music with earphones or ear buds the sound vibrations damage the eardrum.

Ringing of the ear is called Tinnitus.\nInside your inner ear, thousands of auditory cells maintain an electrical charge. Microscopic hairs form a fringe on the surface of each auditory cell. When they're healthy, these hairs move in relation to the pressure of sound waves. The movement triggers the cell to discharge electricity through the auditory nerve. Your brain interprets these signals as sound.\n\nIf the delicate hairs inside your inner ear are bent or broken, they move randomly in a constant state of irritation. Unable to hold their charge, the auditory cells "leak" random electrical impulses to your brain as noise.\n\nDamage to auditory cells in your inner ear most commonly results from:\n\nAge-related hearing loss (presbycusis). This process usually begins around age 60. \nNoise-related damage to your inner ear. This erosion of your hearing ability may result from excessive exposure to loud noise over a long period of time. Tractors, chain saws and weapons are common sources of noise-related hearing loss. Portable music devices, such as MP3 players or iPods, may become a common source of noise-related hearing loss in the future if people play these devices loudly for long periods. \nOther causes of tinnitus may include:\n\nLong-term use of certain medications. Aspirin used in large doses and certain types of antibiotics can affect inner ear cells. Often the unwanted noise disappears when you stop using these drugs. \nChanges in ear bones. Stiffening of the bones in your middle ear (otosclerosis) may affect your hearing. \nInjury. Trauma to your head or neck can damage your inner ear. \nCertain disorders of your blood vessels can cause a type of tinnitus called pulsatile tinnitus. These may include:\n\nAtherosclerosis. With age and buildup of cholesterol and other fatty deposits, major blood vessels close to your middle and inner ear lose some of their elasticity — the ability to flex or expand slightly with each heartbeat. That causes blood flow to become more forceful and sometimes more turbulent, making it easier for your ear to detect the beats. \nHigh blood pressure. Hypertension and factors that increase blood pressure, such as stress, alcohol and caffeine, can make the sound more noticeable. Repositioning your head usually causes the sound to disappear. \nTurbulent blood flow. Narrowing or kinking in a carotid artery or jugular vein can cause turbulent blood flow and head noise. \nMalformation of capillaries. A condition called A-V malformation, which occurs in the connections between arteries and veins, can result in head noise. \nHead and neck tumors. Tinnitus may be a symptom of a tumor in your head or neck.  \n\nSo as not to cause panic.  Maybe it's just a simple case of water trapped in your ear. or an infection called otitis media.  It would be prudent for you to go see an EENT for proper diagnosis. and treatment.  All you need might only be an ear irrigation.\n\nTinnitus is usually caused by a head injury, an infection, such as colds or sinus infection or sinusitis, a disease or exposure to loud sounds such as gunshots and explosions.\n\nIt can be a sign of hearing loss, or it can result from head injuries, or diseases that range from the common cold to diabetes. People who work with noisy equipment, such as power tools, can also get it. Or tinnitus may be initiated by a single loud noise, such as a gunshot or an explosion. It can also be a symptom of almost any ear disorder, including the following:\n\n Ear infections \n Blocked ear canal \n Blocked eustachian tube \n Otosolerosis \n Tumors of the middle ear \n Meniere's disease \n Damage to the ear caused by drugs (such as aspirin and some antibiotics) \n Hearing loss \n Blast injury from a blast or explosion \n\nTinnitus may also occur with other disorders such as anemia, heart and blood vessel disorders including hypertension and arteriosclerosis, and low thyroid hormone levels in the blood (hypothyroidism).\n\nA wide variety
