Question: What is (are) Hearing Loss ?
Answer: Hearing loss is a common problem caused by noise, aging, disease, and heredity. Hearing is a complex sense involving both the ear's ability to detect sounds and the brain's ability to interpret those sounds, including the sounds of speech. Factors that determine how much hearing loss will negatively affect a persons quality of life include - the degree of the hearing loss - the pattern of hearing loss across different frequencies (pitches) - whether one or both ears is affected - the areas of the auditory system that are not working normallysuch as the middle ear, inner ear, neural pathways, or brain - the ability to recognize speech sounds - the history of exposures to loud noise and environmental or drug-related toxins that are harmful to hearing - age. the degree of the hearing loss the pattern of hearing loss across different frequencies (pitches) whether one or both ears is affected the areas of the auditory system that are not working normallysuch as the middle ear, inner ear, neural pathways, or brain the ability to recognize speech sounds the history of exposures to loud noise and environmental or drug-related toxins that are harmful to hearing age. A Common Problem in Older Adults Hearing loss is one of the most common conditions affecting older adults. Approximately 17 percent, or 36 million, of American adults report some degree of hearing loss. There is a strong relationship between age and reported hearing loss: 18 percent of American adults 45-64 years old, 30 percent of adults 65-74 years old, and 47 percent of adults 75 years old, or older, have a hearing impairment. Men are more likely to experience hearing loss than women. People with hearing loss may find it hard to have a conversation with friends and family. They may also have trouble understanding a doctor's advice, responding to warnings, and hearing doorbells and alarms. Types of Hearing Loss Hearing loss comes in many forms. It can range from a mild loss in which a person misses certain high-pitched sounds, such as the voices of women and children, to a total loss of hearing. It can be hereditary or it can result from disease, trauma, certain medications, or long-term exposure to loud noises. There are two general categories of hearing loss. - Sensorineural hearing loss occurs when there is damage to the inner ear or the auditory nerve. This type of hearing loss is usually permanent. - Conductive hearing loss occurs when sound waves cannot reach the inner ear. The cause may be earwax build-up, fluid, or a punctured eardrum. Medical treatment or surgery can usually restore conductive hearing loss. Sensorineural hearing loss occurs when there is damage to the inner ear or the auditory nerve. This type of hearing loss is usually permanent. Conductive hearing loss occurs when sound waves cannot reach the inner ear. The cause may be earwax build-up, fluid, or a punctured eardrum. Medical treatment or surgery can usually restore conductive hearing loss. What is Presbycusis? One form of hearing loss, presbycusis, comes on gradually as a person ages. Presbycusis can occur because of changes in the inner ear, auditory nerve, middle ear, or outer ear. Some of its causes are aging, loud noise, heredity, head injury, infection, illness, certain prescription drugs, and circulation problems such as high blood pressure. Presbycusis commonly affects people over 50, many of whom are likely to lose some hearing each year. Having presbycusis may make it hard for a person to tolerate loud sounds or to hear what others are saying. Tinnitus: A Common Symptom Tinnitus, also common in older people, is a ringing, roaring, clicking, hissing, or buzzing sound. It can come and go. It might be heard in one or both ears and be loud or soft. Tinnitus is a symptom, not a disease. It can accompany any type of hearing loss. It can be a side effect of medications. Something as simple as a piece of earwax blocking the ear canal can cause tinnitus, but it can also be the result of a number of health conditions. If you think you have tinnitus, see your primary care doctor. You may be referred to an otolaryngologist -- a surgeon who specializes in ear, nose, and throat diseases -- (commonly called an ear, nose, and throat doctor, or an ENT). The ENT will physically examine your head, neck, and ears and test your hearing to determine the appropriate treatment. Hearing Loss Can Lead to Other Problems Some people may not want to admit they have trouble hearing. Older people who can't hear well may become depressed or may withdraw from others to avoid feeling frustrated or embarrassed about not understanding what is being said. Sometimes older people are mistakenly thought to be confused, unresponsive, or uncooperative just because they don't hear well. Hearing problems that are ignored or untreated can get worse. If you have a hearing problem, you can get help. See your doctor. Hearing aids, special training, certain medicines, and surgery are some of the choices that can help people with hearing problems.

Question: How to prevent Hearing Loss ?
Answer: Causes of Hearing Loss Hearing loss happens for many reasons. Some people lose their hearing slowly as they age. This condition is called presbycusis. Doctors do not know why presbycusis happens, but it seems to run in families. Another cause is the ear infection otitis media, which can lead to long-term hearing loss if it is not treated. Hearing loss can also result from taking certain medications. "Ototoxic" medications damage the inner ear, sometimes permanently. Some antibiotics are ototoxic. Even aspirin at some dosages can cause problems, but they are temporary. Check with your doctor if you notice a problem while taking a medication. Heredity can cause hearing loss, but not all inherited forms of hearing loss take place at birth. Some forms can show up later in life. In otosclerosis, which is thought to be a hereditary disease, an abnormal growth of bone prevents structures within the ear from working properly. A severe blow to the head also can cause hearing loss. Loud Noise Can Cause Hearing Loss One of the most common causes of hearing loss is loud noise. Loud noise can permanently damage the inner ear. Loud noise also contributes to tinnitus, which is a ringing, roaring, clicking, hissing, or buzzing sound in the ears. Approximately 15 percent (26 million) of Americans between the ages of 20 and 69 have high frequency hearing loss due to exposure to loud sounds or noise at work or in leisure activities. Avoiding Noise-Induced Hearing Loss Noise-induced hearing loss is 100 percent preventable. You can protect your hearing by avoiding noises at or above 85 decibels in loudness, which can damage your inner ear. These include gas lawnmowers, snowblowers, motorcycles, firecrackers, and loud music. Lower the volume on personal stereo systems and televisions. When you are involved in a loud activity, wear earplugs or other hearing protective devices. Be sure to protect children's ears too. Although awareness of noise levels is important, you should also be aware of how far away you are from loud noise and how long you are exposed to it. Avoid noises that are too loud (85 decibels and above). Reduce the sound if you can, or wear ear protection if you cannot. Potential damage from noise is caused by the loudness of the sound and the amount of time you are exposed to it. If you experience tinnitus or have trouble hearing after noise exposure, then you have been exposed to too much noise. Other Ways to Prevent Hearing Loss There are other ways to prevent hearing loss. - If earwax blockage is a problem for you, ask you doctor about treatments you can use at home such as mineral oil, baby oil, glycerin, or commercial ear drops to soften earwax. - If you suspect that you may have a hole in your eardrum, you should consult a doctor before using such products. A hole in the eardrum can result in hearing loss and fluid discharge. - The ear infection otitis media is most common in children, but adults can get it, too. You can help prevent upper respiratory infections -- and a resulting ear infection -- by washing your hands frequently. - Ask your doctor about how to help prevent flu-related ear infections. If you still get an ear infection, see a doctor immediately before it becomes more serious. - If you take medications, ask your doctor if your medication is ototoxic, or potentially damaging to the ear. Ask if other medications can be used instead. If not, ask if the dosage can be safely reduced. Sometimes it cannot. However, your doctor should help you get the medication you need while trying to reduce unwanted side effects.

Question: What are the symptoms of Hearing Loss ?
Answer: Don't Ignore Hearing Problems Some people have a hearing problem without realizing it. Others might think they have a problem, but are too embarrassed to tell their doctor, friends, or family. You can help identify a possible hearing problem by asking yourself some key questions and, if necessary, having your hearing checked by a doctor. If a hearing loss is ignored or untreated, it can get worse. But a hearing loss that is identified early can be helped through treatment, such as hearing aids, certain medications, and surgery. Do You Have A Hearing Problem? Ask yourself the following questions. If you answer "yes" to three or more of these questions, you could have a hearing problem and may need to have your hearing checked by a doctor. - Do I have a problem hearing on the telephone? - Do I have trouble hearing when there is noise in the background? - Is it hard for me to follow a conversation when two or more people talk at once? - Do I have to strain to understand a conversation? - Do many people I talk to seem to mumble or not speak clearly? - Do I misunderstand what others are saying and respond inappropriately? - Do I often ask people to repeat themselves? - Do I have trouble understanding women and children when they talk? - Do people complain that I turn the TV volume up too high? - Do I hear a ringing, roaring, clicking, buzzing, or hissing sound a lot? - Do some sounds seem too loud? Do I have a problem hearing on the telephone? Do I have trouble hearing when there is noise in the background? Is it hard for me to follow a conversation when two or more people talk at once? Do I have to strain to understand a conversation? Do many people I talk to seem to mumble or not speak clearly? Do I misunderstand what others are saying and respond inappropriately? Do I often ask people to repeat themselves? Do I have trouble understanding women and children when they talk? Do people complain that I turn the TV volume up too high? Do I hear a ringing, roaring, clicking, buzzing, or hissing sound a lot? Do some sounds seem too loud? Sudden sensorineural hearing loss, or sudden deafness, is a rapid loss of hearing. It can happen to a person all at once or over a period of up to 3 days. It should be considered a medical emergency. If you or someone you know experiences sudden sensorineural hearing loss, you should visit a doctor immediately. Who Should I See? The most important thing you can do if you think you have a hearing problem is to seek professional advice. There are several ways to do this. You may start with your primary care physician, an otolaryngologist, an audiologist, or a hearing aid specialist. Each has a different type of training and expertise. Each can be an important part of your hearing health care. An otolaryngologist -- a surgeon who specializes in ear, nose, and throat diseases -- will try to find out why you have a hearing loss and offer treatment options. He or she will ask you for your medical history, ask if other family members have hearing problems, perform a thorough exam, and prescribe any needed tests. An audiologist is a health professional who can identify and measure hearing loss. The audiologist will use a device called an audiometer to test your ability to hear sounds of different loudness and pitch (where the sound falls on the scale, from high to low). The tests that an audiologist performs are painless. Audiologists do not prescribe medications or perform surgery. If you need a hearing aid, some audiologists are licensed to help you choose the right one. A hearing aid specialist (or hearing aid dispenser) is a licensed professional that can check your hearing, fit a hearing aid, counsel and rehabilitate, evaluate treatment for tinnitus, and help with swim molds, ear molds, and noise protectors.

Question: How to prevent Hearing Loss ?
Answer: Washing your hands frequently can help prevent upper respiratory infections, which can lead to an ear infection called otitis media. The ear infection otitis media can be a cause of long-term hearing loss. Also, ask your doctor about a yearly flu shot to help prevent flu-related ear infections. If you still get an ear infection, see a doctor immediately before it becomes more serious.

Question: What are the treatments for Hearing Loss ?
Answer: Assistive Listening Devices Assistive listening devices devices can help you hear in certain listening environments. These can include telephone and cell phone amplifying devices, smart phone or tablet "apps," and closed circuit systems (induction coil loops) in places of worship, theaters, and auditoriums. TV listening systems help you listen to the television or the radio without being bothered by other noises around you. Some hearing aids can be plugged into televisions or stereos to help you hear better. Cochlear Implant If your hearing loss is severe and of a certain type, your doctor may suggest that you talk to an otolaryngologist about a cochlear implant. An otolaryngologist is a surgeon who specializes in ear, nose, and throat diseases. A cochlear implant is a small electronic device that the surgeon places under the skin and behind the ear. The device picks up sounds, changes them to electrical signals, and sends them past the non-working part of the inner ear and on to the brain. Hearing through a cochlear implant sounds different from normal hearing, but it lets many people communicate orally in person and over the telephone, and perceive sounds in the environment.

Question: How to prevent Hearing Loss ?
Answer: Researchers funded by the National Institutes of Health are studying the causes of hearing loss as well as new treatments. For example, they are studying ways to improve hearing aids so that you can hear certain sounds more clearly even when you are surrounded by background noise. They are also working to to improve cochlear implants and develop diagnostic methods to determine who would benefit from two versus one cochlear implant, especially in young children. Finding ways to improve access to accessible and affordable hearing health care, including screening and assessment, hearing aid selection and fitting, and rehabilitation of hearing loss, is also a goal of currently funded research.
