Types of Hearing Loss

Conductive Loss

Causes of Conductive Loss can be medically treated Outer: Outer: Wax Buildup, Wax Buildup, Foreign Body Blockage Foreign Body Blockage Swimmer Ear Swimmer Ear Development defect Development defect Middle: Perforation of drum Pressure Ear Infection

Sensory Nueral Loss Permanent; -can not repair damage Inner Ear-most common type of loss

Causes of Sensory-Neural Loss Noise Induced Noise Induced Noise Induced Noise Induced Age Age Genetics/Heredity Genetics/Heredity Illness Illness Accidents Medicine Drugs Genetic Syndrome

Noise Induced MOST PREVENTABLE! Watch: Wild tour of the ear-how noise damages hearing and

Preventative Measures for noise induced sensory-neural loss 1)Protective Ear Wear 2)Turn down the volume 3)Avoid noisy/loud situations

Sound: vibrations that travel in waves

Frequency: -how fast vibrations travel. Hertz (Hz) -slower the wave the lower the pitch -faster the wave the higher the pitch

FREQUENCY IN CYCLES PER SECOND (HZ) LOW PITCH HIGH PITCH

Intensity -how loud the sound is. Decibels (dB) -bigger the wave, louder the sound -smaller the wave, softer the sound

HEARING LEVEL (dB HL) LOUD SOFT

People with hearing loss have different degrees of loss in various frequencies. They may have normal hearing in certain frequencies and moderate to severe in other frequencies.

Brain Fills the Gaps

I thought I understood something but, in fact, I didn't. I've begun to realize that misunderstanding is an active process — that my brain fills in the missing pieces that I didn't hear.

Communicating Strategies for with a person who has a hearing loss

Do’s 1. Speak clearly 2. Look directly at the person 3. If saying it one way does not work, rephrase it 4. facial expression tell a great deal 5. Use paper and pencil 6. If they are deaf, ask the person how they want to interact (sign language, speech, lipreading, pen/paper….) Do’s 1. Speak clearly 2. Look directly at the person 3.
