An Overview of Hearing Loss Hearing occurs when the inner structures of your ear receive sound waves. The vibrations take the form of nerve signals which eventually reach your brain and get recognized as sound. Your ear is divided into three major parts, namely, the outer ear, the middle ear, and the inner ear. When sound waves get into the outer ear, they result in vibrations at the eardrum. As these vibrations travel to the inner ear, the eardrum and middle ear (composed of three tiny bones called the hammer, anvil and stirrup) work together to amplify them. These vibrations eventually end up in the inner ear structure called the cochlea. There are nerve cells found in the cochlea, and attached to them are multitudes of tiny hairs. The hairs capture the vibrations and transform them into electrical signals for transmission to your brain. Different signals will get to your brain because the hairs will be affected by the different sounds in different ways. This is how you tell one sound from the other. Why No One Talks About Options Anymore Factors Behind Hearing Loss The Beginners Guide To Hearing (Finding The Starting Point) A lot of things may figure into why hearing loss occurs, but mostly, it has something to do with a damaged inner ear. When the hairs or nerve cells are damaged, a results will be the inefficient transmission of electrical signals. Things may sound muffled, and you might have a hard time distinguishing words and noise. Heredity plays a huge role in why these things can happen. This is called sensorineural hearing loss, and there is no treatment for it. Another reason for hearing loss is earwax blocking the ear canal and stopping sound wave conduction. This is called conductive hearing loss, and it is easily corrected by removing the earwax. Hearing loss could also be caused by the growth of abnormal bones or tumors or ear infections in the middle or outer ear, along with a ruptured eardrum. Hearing Loss Vulnerability There are several factors that could lead to the damage or loss of nerve cells and hairs in your inner ear. Age, for example, naturally causes the cells in your inner hear to wear down. Your genetic make-up can also be a huge factor. If you work in a naturally noisy area, such as a factory or at a farm, your inner ear could also develop problems. Noise from firearms and fireworks and other forms of recreational noise may bring about sudden and irreversible hearing loss. Other recreational activities that may have the same effect are those coming from motorcycling or loud music. If you listen to music at a volume that is enough to drown out loud sounds such as those produced by a lawn mower, your inner ear can also be permanently damaged. Some drugs and diseases, like meningitis, can also bring about hearing loss. If you’re having problems with your hearing and would like to take a hearing test in Riverside, use the Internet to locate a good center near you. Or your friends, relatives or colleagues can always give you a few pointers if you ask them. No related posts.

uho se sastoji od nekoliko dijelova , počevši od vanjskog uha , koja prikuplja i sprovodi zvučne valove u vašem srednjeg uha . Vaš srednjeg uha je odvojen od vanjskog uha po vašem bubnjića . Ovaj dio uha ima Malleus (čekić) , nakovanj ( nakovanj ) i stapes ( stremen ) . Ove tri kosti uvećati pokret bubnjić kad zvučni valovi ulaze . Eustahijeva cijev spaja uho na stražnji dio grla izjednačiti tlak zraka . Vaše unutarnje uho sadrži pužnica , koji osjeća zvučne vibracije te ih prolazi do mozga putem vašeg kohlearni živac . Mehanički kvar Provodivi gluhoća može rezultirati iz kostiju u svom srednjeg uha neispravnosti , što bi moglo značiti da zvučni valovi se ne šalju svoje unutarnje uho , kao i obično bi trebao biti . Kosti u vašem srednjeg uha mogu biti " zamrznut " od nakupljanja kalcija , što znači da se neće pomaknuti koliko i slobodno kao što im je potrebno kako bi za vas da se čuje jasno . bubnjić Smetnja bubnjić ne može se njiše , kao što bi trebao biti . Kada vaš bubnjić ne vibrira , zvučni valovi se ne krene prema vašem unutarnjem uhu za pužnice kako bi pokupili . Vi svibanj imati infekcije uha sprječava bubnjić iz radi ispravno . Ili ste možda patio od nekoliko uha kao dijete . Ovih zadnjih upale uha mogu trajno utjecati na funkciju vašeg bubnjića . Nakupljanja tekućine nakupljanje tekućine u ušni kanal , u blizini bubnjića , možda navlažiti Zvučni valovi ' pokret prema bubnjića . Te nakupine će blokirati provođenje zvuka u vašem unutarnjem uhu . Dok ste u mogućnosti čuti , zvukovi vi pokupiti će biti prigušen i slaba . Vosak buildup nakupljanje ušni vosak u uho kanal može blokirati zvuk valova iz dostizanje vašeg srednjeg i unutarnjeg uha . Vaš zvukovoda učinkovito spriječiti primanje zvučnih valova morate čuti .
