  2. 2. How can we hearThe ear is made up of 3 different parts.S Inner earS Middle earS Outer earThe pinna (outer ear) picks up sound wave and the wavesthen travel through the outer ear canal.
  3. 3. How to hearWhen the sound waves hit the eardrum in the middle ear, theeardrum starts to vibrate. When the eardrum vibrates, it moves 3tiny bones called hammer, anvil and stirrup.They help sound move along into the inner ear.The vibration then travel to the cochlea, which is filled withliquid and lined with cells that have thousands of tiny hairs ontheir surfaces. The sound vibration make the tiny hairs move.Than it travels to your brain, allowing you to hear.
  4. 4. IllnessWe will talk about chronic ear infection(otitis media). Otitis media is an inflammation in themiddle ear.
  5. 5. How commonS Otitis media is the most frequently diagnosed disease in infants and young children. Seventy- five percent of children experience at least one episode of otitis media by their third birthday.
  6. 6. How can it cause a hearing lossThree tiny bones in the middle ear carry sound vibrationsfrom the eardrum to the inner ear. When you get otitismedia, the vibrations are not transmitted efficiently andsound energy is lost. The result may be mild or even moderatehearing loss. Generally, this type of hearing loss is temporary.However, when otitis media occurs over and over again,damage to the eardrum, the bones of the ear, or even thehearing nerve can occur and cause a permanent hearingloss.
  7. 7. Hearing aidsHearing aids help people who can’t listen well.There are 3~4 types of hearing aids.S Behind-the-ear (BTE) hearing aidsS In-the-ear (ITE) hearing aidsS In-the-canal (ITC) hearing aidsS Intra-canal (CIC) hearing aidsbut the most common ones are BTE and ITE.
  8. 8. BTE Hearing aidsThese have 2 main parts. A small hard plastic case goes behind the earthat holds the electronics that make up the actual hearing aids.It’s connected to a plastic piece called an ear mold that fits inside theoutermost part of the ear.Sound travels from the hearing aid through the ear mold and into theear. BTEs are used by people of all ages to treat hearing loss.
  9. 9. ITE Hearing aidsThese fit completely inside the outer ear. They can help with mildto severe hearing loss. As with BTEs, theres a hard plastic casethat holds the electronic components, but in this case its joined tothe ear mold itself, so its all one piece.

Thecost of a advanced digital hearing aid per day is $3.You have to pay again if the otitis media happens over andover
