- Consistent use of amplification and language intervention prior to age 6 months increases the probability that the child's speech, language and learning will develop at a ormal rate.
- Without amplification, child may understand conversation at a distance of 3-5 feet, if sentence structure and vocabulary are known.
- The amount of speech signal missed can be 50% or more with 40 dB loss and 80% or more with 50 dB loss.
- Without early amplification the child is likely to have delayed or disordered syntax, limited vocabulary, imperfect speech production and flat voice quality.
- Addition of a visual communication system to supplement audition may be indicated, especially if language delays and/or additional disabilities are present.
- Even with hearing aids, child can "hear" but may miss much of what is said if classroom is noisy or reverberant.
- With personal hearing aids alone, ability to perceive speech and learn effectively in the classroom is at high risk.
- A personal FM system to overcome classroom noise and distance is typically necessary.

- Barriers build with negative impact on self-esteem as child is accused of "hearing when he/she wants to," "daydreaming," or "not paying attention."
- Communication will be significantly compromised with this degree of hearing loss, if hearing aids are not worn.
- Socialization with peers can be difficult, especially in noisy settings such as cooperative learning situations, lunch or recess.
- May be more fatigued than classmates due to effort needed to listen.
|
- Consistent use of amplification (hearing aids + FM) is essential.
- Needs favorable classroom acoustics, seating and lighting.
- Consultation/program supervision by a specialist in childhood hearing impairment to coordinate services is important.
- Depending on early intervention success in preventing language delays, special academic support will be necessary if language and educational delays are present.
- Attention to growth of oral communication, reading, written language skills, auditory skill development, speech therapy, self-esteem likely.
- Teacher inservice required with attention to communication access and peer acceptance.
