Deafness People can become deaf or hard of hearing for a variety of reasons Including: Genetics  Illness ( meningitis, measles, mumps, AIDS...etc)  Environmental noise ( ipods, prolonged exposure to loud noises)  Sensorineural hearing loss ( portions of the inner ear are not sensitive to noise)  Conductive loss ( sound does not travel through the ear)  Physical Trauma 

Levels of Deafness Not all individuals who are deaf have the same degree of hearing loss Sometimes hearing is better in one ear than the other Hearing loss is measured in decibels 

Mild:  for adults: between 25 and 40 dB  for children: between 20 and 40 dB

Moderate: between 41 and 55 dB  Moderately severe: between 56 and 70 dB  Severe: between 71 and 90 dB  Profound: 90 dB or greater ( Indicates the lowest noise an individual can detect) 

Common noises Painful 150 dB = rock music peak 140 dB = firearms, air raid siren, jet engine 130 dB = jackhammer 120 dB = jet plane take-off, amplified rock music at 4-6 ft., car stereo, band practice Extremely Loud 110 dB = rock music, model airplane 106 dB = timpani and bass drum rolls 100 dB = snowmobile, chain saw, pneumatic drill 90 dB = lawnmower, shop tools, truck traffic, subway Very Loud 80 dB = alarm clock, busy street 70 dB = busy traffic, vacuum cleaner 60 dB = conversation, dishwasher Moderate 50 dB = moderate rainfall 40 dB = quiet room

Hard of Hearing Many people with hearing loss have better hearing in the lower frequency ranges (low tones), and cannot hear in the higher frequencies. Some people find it difficult to differentiate between z, and th, or d, t, b, and p. They may be unable to hear thin, high-pitched or metallic noises, such as birds chirping or singing, clocks ticking, Often are sensitive to noise in the environment

Technology used by the Deaf Hearing Devices 

Hearing Aids



Fm Devices



Cochlear Implants

Hearing Aids Are fitted and set up by qualified Audiologists Amplify sounds, but do not restore hearing Are moulded to an individual’s ears

Fm Device Has a receiver and an earpiece Used in classrooms, or when someone is giving a speech Attaches to the hearing aid or cochlear implant, while the speaker has a receiver which is attached to a small microphone

Cochlear Implants Electronic device which has one portion implanted into the inner ear, while the other portion rests outside Outside portion consists of a microphone and processor which sends a signal to the inside portion The inside portion stimulates the nerve endings in the cochlea, producing nerve impulses. The impulses are sent to the brain where they are interpreted as sound. Is not a “cure” for deafness but currently the best technology to improve hearing in deaf individuals

Other Technologies Video Phones Texting Flashing alarms, flashing/vibrating alarm clocks TTY devices
