Hearing Loss
It is estimated that over 28 million Americans suffer from hearing impairment. The onset of hearing loss may develop very subtly. Many are not aware of hearing loss until a family member or friend expresses concern. Recognizing hearing loss is the first step toward treatment. A hearing test can easily identify the amount and type of hearing loss.
Types and Causes of Hearing Loss
Types of hearing loss include conductive and sensorineural. Conductive hearing loss is caused by damage to or blockage of the ear canal or middle ear. Most people have experienced some degree of conductive loss when they have had ear infections or substantial amounts of earwax. In most cases conductive loss is correctible but in some cases the damage is such that it cannot be reversed and hearing devices are the best option for improving speech understanding.
Sensorineural loss is permanent and is the result of damage to the nerve cells responsible for detecting and transmitting sound to the brain. Causes of nerve damage include: noise exposure, normal aging, certain medical conditions, genetic predisposition and very rarely tumors. There is a common misconception that hearing devices cannot help people with sensorineural hearing loss. In reality, most people with sensorineural hearing loss receive significant benefit from hearing devices especially in more difficult listening situations. This benefit continues to grow as modern technology continues to improve. Hearing devices cannot restore normal hearing but they can make life more social, more comfortable and more productive for many individuals.
