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.
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.
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.
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.
PARTS OF THE EAR
*However the three main parts of the ear are The Inner, Middle, and Outer Ear*
THE
INNER E
AR
• 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.
THE
OUTER E
AR
• 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.
THE
MIDDLE
EAR
• Its main function is to transfer acoustic energy from compression waves in air to fluid- membrane waves within the cochlea.
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.
