1. HOW DO SOUND VIBRATIONS RELATE TO THE MEDICAL FIELD? VS. BY: EBON’E NESMITH

2. ULTRASOUND IMAGES Ultrasonic waves can be used to see images of objects inside the body. In order for ultrasonic waves to “see” an object inside the body, the wavelength of the waves used must be about the same size as the object or smaller. A typical frequency used in an ultrasonic device is about 10 MHz. Physicians often use ultrasonic waves to observe fetuses. These reflected sound waves are converted to an electrical signal, forms an image on a fluorescent screen. These images help doctors catch abnormalities that a child may have in the fetus.

3. SENSORINERUAL HEARING LOSS THIS OCCURS WHEN THE INNER EAR STARTS TO ACT UP. MORE THAN 90% OF HEARING AID WEARERS HAVE SENSORINERUAL HEARING LOSS. THE CAUSES OF SENSORINERUAL ARE: CHANGING OF AGE, NOISE EXPOSURE, BLEEDING INSIDE THE EAR, VARIOUS DISEASES (MENINGITIS, DIABETES, CHICKEN POX) ETC. SENSORINERUAL HEARING LOSS IS PERMANENT AND THE ONLY CHOICE IS GETTING A HEARING AID.

4. CONDUCTIVE HEARING LOSS It occurs when sounds does not going through the ear canal, which causes you not to hear as loudly as before. Conductive hearing loss is caused by ear wax, fluid in the middle ear, middle ear infections, and deformations. The person with this condition may talk softly because they hear themselves loudly. The person might also have to stop chewing to hear. The may also be permanent if it was caused by a disease otherwise medical treatment can be provided.

5. WHAT CAUSED BEETHOVEN’S DEATH? The cause of Beethoven’s death occurred from Ostosclerosis. Ostoslerosis is a disease, which an abnormal growth of the bone appears in the inner ear. In result, the bones blocks the sound and can not be passed to the inner ear. However, this relates to the Conductive Hearing Loss. The bigger the bone grows the larger amount of hearing loss is taken away. Therefore, Beethoven’s hearing worsened and he couldn’t hear anymore.

6. PARTS OF THE EAR * However the three main parts of the ear are The Inner, Middle, and Outer Ear*

7. THE INNER EAR The inner ear is the hardest bone of the ear. It transfers the sound impulses from the outer ear into electrical impulses to the brain. The cochlea is the main part of the inner ear it converts sound waves to neural signals.

8. THE OUTER EAR It gathers sound energy and focus it towards the ear drum. It is covered with skin via cartilage. This is the part of the ear where people get pierced to wear earrings. It also collects dirt to keep the ear canal clean.

9. THE MIDDLE EAR Its main function is to transfer acoustic energy from compression waves in air to fluid- membrane waves within the cochlea.

10. Interesting facts!! 37% of children with minimal hearing loss fail atleast one grade. Once you loose your hearing it’s gone forever!! Ear piercings was found on a frozen mummy in 1991.
