 +**This page attempts to visually demonstrate conductive and sensorineural hearing losses, and their relationship to hearing aids.**
  
-For most people, the only kind of hearing loss you'​ve ​been exposed to is a conductive loss; one found when you catch a cold. Though louder sounds can help a conductive loss, hearing aids do little to correct a sensorineural loss, especially for a child, or someone still learning to adapt to a recent loss.+If you're like most people, the only hearing loss you'​ve ​experienced ​is a conductive loss; one found when catching ​a cold.
  
-Hearing ​aids can make sounds louder, but do little to make them clearer. Hearing through ​hearing aid has been described as tuning ​radio slightly off a stationallowing static, and then making it louder. Just as with a hearing ​aid, as the radio plays louder, the static and noise become worse.+Hearing ​Aids are good solutions for conductive losses, but they do little to correct ​sensorineural loss, especially for childor anyone adapting to recent decline in hearing.
  
-This page will demonstrate visually how hearing ​aids work for conductive ​and sensorineural ​hearing ​loss.+Hearing ​aids increase the volume of sound, but can do little to improve clarity. Hearing through a hearing aid is best-described as tuning a radio slightly off-station,​ allowing static, ​and then increasing the volume. Just as with a hearing ​aid, as the radio plays louder, the static and noise worsen.

 You should have been able to easily read the word in the center. This is how a hearing aid works for a conductive hearing loss: once sound is loud enough (bigger) it can be understood. You should have been able to easily read the word in the center.

 +Could you read the word? This second image is an illustration of a sensorineural loss. Even though the hearing aid amplifies sound, it cannot not fill or correct the missing or distorted parts. How much of the word is missing is be affected by the condition of the inner ear, auditory fatigue, listening experiences,​ prior exposure to the word, condition of the earmold, condition of the hearing aid, and general background noise. 
 + 
 +Speech-reading (lip-reading) is a common technique used to fill-in information from missing or distorted words. Even under the best conditions the accuracy of speech-reading only approaches 70%; as you mouth the following words, note the position of your lips: 
 +  - pan 
 +  - ban 
 +  - man.
  
-Could you read the word? This is the way hearing aids work for sensorineural loss. Even though ​the aid amplifies the soundit does not fill or correct the missing or distorted parts of the soundHow much of the word is missing can be affected by things such as condition of the inner ear, auditory fatigue, listening experiencesprior exposure to the word, condition ​of the earmold, condition of the hearing aid, and general background noise.+The position of you lips remains ​the same, for all three words. Even some words you may not think look the samedo; mouth "​red"​ and "​green"​Once again, the position ​of your lips is the same for both words.
  
-Some information ​for filling in the parts of the words that are missing or distorted may be gained through speech-reading (lip-reading). Even under the best conditions only about 60 to 70 percent of speech ​can be understood on the lips. Mouth the words panbanand man. Notice that the position ​of your lips is the same for all 3 words. Even some words you may not think look the samedo. Try mouthing the words red and green. Once againthe position ​of your lips is the same for both words.+Other clues for filling in missing ​parts can be body languagecontexttone of voicerepetitionpictures, or any of a number of different strategies.
  
-Other clues for filling in missing parts can be body languagecontexttone of voice, repetition, pictures, or any of a number of different strategies. ​FM or Sound Field systems ​can be beneficial ​if background noise is adding ​to the problem.+Sometimesother technologies can also helpsuch as FM or Sound Field systemsif the goal is to minimize ​background noise...more details ​to follow on this particular topic...
