SHS unit 2 - Audiologic rehabilitation

Audiologic Rehabilitation

• Adults or those who need to modify communication skills as a result of acquired hearing impairments

Audiologic Habilitation

• Children or those who are listening and learning to use speech and language skills for the first time

Hearing Aid basic components

1. Microphone - picks up sound

2. Amplifier- makes sound louder

3. Receiver - sends sound to ear

4. Battery

Hearing aid advantages

• Ease listening - less strain to hear

• Increased sound awareness

• Help speech understanding

• Improve social involvement and self esteem

Hearing aid disadvantages

• Won't restore hearing to normal

• Unmotivated, reluctant client

• Medical reasons not to wear them

• Medical or surgical options to improve hearing

behind the ear hearing aids

• Many types of losses

• Sturdy - largest style

• Less feedback

• New versions nearly invisible

in the ear hearing aids

• Mild to severe

• Programmable

• Short battery life

completely in canal hearing aids

• Mild to moderate

• Small- difficult to handle

• Short battery life

• Expensive

just in the canal hearing aids

• Mild to moderate

• Short battery life

• Small

steps in the hearing aid process

1. Hearing Aid consultation

• Test hearing, discuss options, earmold impression

2. Hearing aid fitting

• Determining hearing aid specifications

• Goals: Provides audibility for sounds that cannot be heard

• Ensure that the output of the device does not not reach intensities that will cause discomfort of damage to the person

3. Aural rehabilitation groups

Cochlear implants (parts)

• External parts

  • Microphone

  • Signal processor

  • Transmitter

• Internal parts

  • Receiver

  • Electrode array

• Stimulates directly the auditory nerve

Adult candidacy for cochlear implants

• Have severe or profound hearing loss bilaterally’

• Limited benefit from hearing aids

• No other medical problems that put you at risk for surgery

• Strong desire to hear

child candidacy for cochlear implants

• Profound hearing loss both ears

• Can receive little or no benefit from hearing aids

• Will need habilitation
  

• If they get them early and receive therapy, they will develop langauge/speech comparable to regular hearing children

assistive listening devices

• goal is to increase audibility of speech signal

reverberation

 sound reflections

• Hard surfaces - high reverberation

• Soft surfaces - low reverberation

Signal to noise ratio

Positive SNRs - easier to understand

alerting devices

• Help hear sounds like a fire alarm or baby's cry

• May use flashing light, vibrotactile stimulation

audiologic habilitation in children

• Early identification of hearing loss and early intervention is important

• Early audiologic intervention for children

• Many kids with hearing loss use ASL for communication

newborn hearing screening

• Received prior form hospital discharge

• Otoacoustic emission and automated auditory brainstem response most commonly used

• Positive outcomes to catching it early

  • Better language speech and social emotional development

  • Cognitive development similar to peers

  • Lower parental stress

detection

• Being able to identify when a sound is present versus when its not

discrimination

• Recognizing the auditory differences between the sounds being heard

identification

• comprehension

Listening and spoken language strategy

• Emphasis on listening and spoken language development

• Little to no emphasis on learning signed language

bilingual/bicultural approach

• Asl as first language

• written/spoken language as 2nd language
