hearing loss has been called the invisible handicap yet the impact on quality of life can be profound a recent study by the ncoa national council on aging in the us revealed the following hearing impaired persons with untreated hearing loss report increased feelings of depression and anxiety increased paranoia and social phobias more anger and frustration increased introversion and feelings of self criticism they also report decreased overall health decreased social activity and even decreased earning power fortunately the situation can be greatly improved for most people with hearing loss the same study revealed that persons with treated hearing loss through hearing aids and/or medical treatment report better family relationships higher self esteem improved mental health greater feelings of independence and security better overall health and increased social activity innovative hearing solutions

normal hearing to understand hearing loss you must first know a little about how the ear works the human ear is a remarkably complex sound analyzing system capable of detecting sounds over an incredibly wide range of intensity and frequency we usually describe the ear in three main sections the outer ear the middle ear and the inner ear the outer ear serves as a sound collector sound vibrations cause movement of the eardrum which is connected to a chain of three tiny bones in the middle ear the middle ear system serves to intensify the energy of the sound vibrations and delivers them to the cochlea in the inner ear the cochlea is the actual organ of hearing inside the cochlea are thousands of outer ear middle ear inner ear

hair-like cells that are connected to fibers of the hearing nerve these hair cells are sensitive to different frequencies and intensities of sound sound vibrations entering the cochlea cause the hair cells to generate electrochemical signals which travel through the hearing nerve to the brain where they are recognized as sounds a person with normal hearing can hear everything from the faintest whisper of the breeze to the roaring of a jet engine taking off normal hearing alerts us to dangersour ears can give us information about the location and speed of an approaching car for instance with good hearing we are able to listen selectively focusing on one conversation at a loud party and shifting easily to another conversation without missing a word we are able to appreciate the beauty of a string quartet and the sound of a loved one s voice innovative hearing solutions

hearing loss when hearing is lost the sounds of life begin to fade for most people this is a gradual process typically the sounds in the higher frequencies begin to disappear first birds chirping in the trees become fainter and fainter music becomes less clear since the lower frequencies are usually heard better or even normally it isn t unusual for people to think that there is no problem it s easy to forget what things sounded like before especially since many of the softer sounds are things we often tend to tune out anyway 125 0 10 20 30 40 50 60 70 80 90 100 110 120 db 250 500 1000 2000 4000 8000 hz normal mild sp eec h moderate severe s ou nd profound audiogram showing typical hearing loss s

as the hearing loss worsens the sounds necessary for understanding speech begin to be affected soft high frequency consonants are no longer heard and it becomes difficult to reliably distinguish one sound from another at this point it may become obvious that you can hear but you can t always understand what is said especially when there is background noise you need to turn the tv volume louder than before it seems like people mumble sometimes but other times you understand perfectly it is natural to think that the problem must be because other people are not speaking clearly when in fact it is your hearing that is not clear because people can t see or understand your hearing loss they may think you are just being unsociable the comment he can hear perfectly when he wants to is a common complaint from family and friends of the hearing impaired the gradual nature of most hearing loss makes it easy to ignore until it begins to have a major impact on your life if the loss were to happen

so what causes people to lose their hearing as you can see from the previous description the ear is quite complicated a problem with any part of the system can cause a loss of hearing the medical profession defines two main categories of hearing loss conductive hearing loss is caused by any problem in the outer or middle ear that interferes with the transmission of sound this interference can be caused by such things as a large build-up of earwax infections or growths in the outer ear holes in the eardrum a disease called otosclerosis which causes the ossicles to become fixed and unable to vibrate or genetic factors conductive hearing loss can often be corrected or improved with medical intervention but when that is not possible hearing instruments can usually help.

sensorineural hearing loss is the term used to describe problems in the inner ear either in the cochlea hearing nerve or auditory pathway often called nerve deafness this type of hearing loss can be caused by many things but the most common cause is deterioration of the hair cells in the cochlea due to aging and/or exposure to loud sounds 90 of all hearing losses are the sensorineural type this kind of problem can rarely be helped medically but fortunately hearing instruments can help a third type of hearing loss is called mixed hearing loss and is simply a combination of conductive and sensorineural problems many people with mixed hearing loss are also able to benefit from hearing instruments innovative hearing solutions

getting help surveys have shown that most people with a significant hearing loss wait several years before finally seeking help this may be partly due to a reluctance to admit there is a problem but it is certainly related to the gradual nature of most hearing loss and the length of time it takes for an individual to realize that a hearing loss exists when people finally try hearing instruments they are usually amazed to discover how much they had been missing the sooner you become aware that you may have a hearing loss the sooner you can have a thorough hearing evaluation and begin to benefit from the appropriate treatment for further information please read bernafon s publication understanding hearing instruments
