Hearing loss is one of the most widespread health problems in the United States. And because it is usually painless, invisible and is clouded with so much misinformation, many people are confused when it comes to making decisions about their hearing health. At HearWell Audiology, serving patients in the Los Gatos, Sonoma and San Jose areas in California, we understand the apprehension that is associated with hearing loss and hearing devices. We believe providing you with accurate information is empowering, and will assist you in making the right choices in treating your hearing loss. We don’t make decisions for you, we work with you, as your partner on your journey to better hearing. One of the first steps on this journey is to ascertain your type of hearing loss. It will help us determine which treatment options are available. There are three main types of hearing loss: sensorineural, conductive and mixed. Sensorineural hearing loss occurs from damage to the cochlea (inner ear) or to the pathways from the cochlea to the brain. This is the most common type of hearing loss. - Often treated with hearing devices, but if your hearing loss is too severe, cochlear implants may be considered, contingent on certain qualifying factors. - Exposure to loud sounds (noise-induced hearing loss or NIHL) aging, ototoxic medications, head trauma, and certain illnesses are possible causes. Conductive hearing loss develops when sound cannot travel through the ear canal to the eardrum and the bones in the middle ear, resulting in limited sound. - Treatment options will be based on the severity of hearing loss and include surgery, medications, hearing devices, or possibly an implantable direct bone conduction system. - Malformation of the ear, ear infections, allergies, perforated ear drum, swimmer’s ear are just some of the causes of this type of hearing loss. Mixed hearing loss is a combination of both sensorineural and conductive factors. There may be damage to the cochlea or auditory nerve as well as to the damage to the outer or middle ear. - Treatment options depend on severity of hearing loss and include hearing devices, surgery, medications, or an implantable direct bone conduction system. Knowing your type of hearing loss and understanding what it means are crucial in deciding on a course of treatment.

Oštećenja sluha možemo podijeliti u dvije skupine: nagluhost i gluhoća. Nagluhost je veće ili manje oštećenje sluha dok se gluhoćom smatra gubitak sluha u govornim frekvencijama (500 do 4000 Hz) veći od 93 decibela. Prema stupnju oštećenja sluha razlikujemo: - uredan sluh - do 10 dB na uhu s boljim ostacima sluha u govornim frekvencijama - sluh u fiziološkim granicama - od 11 do 26 dB na uhu s boljim ostacima sluha u govornim frekvencijama - lakša (blaga) nagluhost - od 27 do 40 dB na uhu s boljim ostacima sluha u govornim frekvencijama - umjerena nagluhost - od 41 do 60 dB na uhu s boljim ostacima sluha u govornim frekvencijama - teška nagluhost - od 61 do 80 db na uhu s boljim ostacima sluha u govornim frekvencijama - praktična gluhoća - od 81 do 93 dB na uhu s boljim ostacima sluha u govornim frekvencijama Razlikujemo 3 vrste nagluhosti : - konduktivna (provodna) nagluhost (hypoacusis conductiva) – oštećenje zračne i koštane vodljivosti zvuka. Mjesto oštećenja je u vanjskom ili u srednjem uhu, tj. otežano provođenje zvučnog vala u unutarnje uho. Uzroci su: začepljenje slušnog kanala ušnom masti, urođene malformacije vanjskog i srednjeg uha, ograničena pokretljivost bubnjića i slušnih koščica, ozljede srednjeg uha, upale uha, timpanoskleroza, otoskleroza, itd. - perceptivna (zamjedbena) nagluhost (hypoacusis perceptiva) – poremećaj zamječivanja intenziteta i frekvencije slušne poruke. Uzroci su: upale unutarnjeg uha, Menierova bolest, izloženost buci, urođena nagluhost, staračka nagluhost, ozljede unutarnjeg uha, tumori slušnog živca, itd. - mješovita nagluhost (hypoacusis mixta) – kombinacija konduktivne i perceptivne nagluhosti. Najčešće nastaje uslijed prelaska oboljenja sa srednjeg na unutarnje uho. Slušna pomagala sastoje se od mikrofona, pojačala i slušalice. Ona funkcioniraju na principu prijenosa zvuka zračnom vodljivošću, a koristimo ih najčešće jer su i perceptivne nagluhosti najbrojnije. Mikrofon prima slušni signal kojeg pojačalo pojačava (i vrši digitalnu obradu signala kod današnjih slušnih pomagala), a slušalica obrađeni signal prosljeđuje u zvukovod prema bubnjiću. Obzirom na izgled i smještaj, razlikujemo 5 osnovnih skupina ovakvih slušnih pomagala: Što dalje? Saznajte Vaš sljedeći korak
